The mean number of letters read correctly on the LogMAR chart was an indicator of visual acuity (VA). View More Cataract . 2 The Many "Flavors" of Cataracts Nuclear Sclerotic Cataract: A nuclear sclerotic cataract is the most common type of aging cataract. The relationship between central nuclear scatter and perinuclear retrodots in the human crystalline lens. Arch Ophthalmol 1983; 101: 19351937. PubMed Furthermore, 15.2% of eyes with vacuoles and 10.5% of eyes without vacuoles at baseline required cataract surgery over the follow-up period (Table 4). Fifty-eight percent of surgeons say they regularly use toric lenses, and shared their views on these lenses' pros and cons. Arch . In cross-sectional analyses using baseline data, we found that mean VA of the three retrodot groups decreased with increasing severity of retrodots before adjusting for age, gender, and cataract at baseline (52.6 vs 48.9 vs 43.9 for no retrodots, retrodots involving 13 subfields and retrodots involving 4+ subfields, respectively, P for trend<0.0001). Discrete logistic regression23 was used to assess the association between baseline retrodots and vacuoles and incidence of each cataract type incorporating discrete time information from both follow-up visits. The .gov means its official. Glare from intense light sources, such as car headlights, is common. Vacuoles were also more frequent in eyes with cataract, observed from baseline data (Table 3). Nuclear sclerotic cataract (NS) - Cloudiness of the nucleus, the central portion of the lens. Ophthalmic Epidemiol 1997; 4: 207212. The site is secure. Vacuoles and more dense granular deposits (plaques) can progress peripherally in a sharply . This is achieved through a unique aspheric anterior surface which adds to the positive spherical aberration (SA) of the cornea in a controlled manner. Vacuoles have previously been considered to be a component of PSC cataract,1 so that the association found between vacuoles at baseline and the prevalence and incidence of PSC cataract would be expected. Rinsho Ganka 2005; 59: 903906. Odds ratios (OR) and 95% confidence intervals (CI) are presented. Epub 2014 May 13. Most eyes (74%) had 12 vacuoles present (Figure 3).

Maraini G, Pasquini P, Sperduto RD, Bonacini M, Carrieri MP, Corona R, Graziosi P, Tomba MC, Williams SL. This is the first reported electron-microscopic evaluation of lens changes in electric cataracts. After adjusting for age, gender, smoking, hypertension, diabetes, education, and use of inhaled/oral steroids, baseline retrodots were associated with an increased incidence of cataract surgery (OR 2.90, 95% CI 1.71-4.91), while 3+ vacuoles at baseline were associated with an increased risk of PSC cataract (OR 3.56, 95% CI 2.13-5.95) and cataract surgery (OR 1.84, 95% CI 1.22-2.77). Morphological correlations of clinical lens changes: non-opaque lens defects. Bron AJ, Brown NA . You are young and will probably not develop cataract for quite some time. 2002 Jul;43(7):2105-9. Provided by the Springer Nature SharedIt content-sharing initiative, Eye (Eye) Vacuoles were associated with a higher risk of prevalent and incident PSC cataract, while the presence of three or more vacuoles or the presence of any retrodots at baseline was associated with an increased likelihood of subsequent cataract surgery. To investigate associations with increasing severity of retrodots and vacuoles, they were each divided into three groups (retrodots: absence, presence in 13 subfields or 4+ subfields; vacuoles: absence, presence of 12 vacuoles or 3+ vacuoles). Hosmer DW, Lemeshow S . PubMed Nuclear vacuoles were found in 11 out of 25 patients treated with hyperbaric oxygen compared to 19 out of 100 pre-operatively examined senile nuclear cataracts. ocular complications are encountered following ionising radiation on the eye. Transient Lens Vacuoles In Premature Infants - Journal Of American www.jaapos.org. Cataracts are a clouding of the lens in the eye. Eyes with 3+ vacuoles had a 50% increase in the odds of visual impairment, after adjusting for age, gender, and cataract at baseline (OR 1.52, 95% CI 1.112.08; Table 3). Confirmation of our study findings and understanding of the links between these lens features and PSC cataract warrants further study. Age-related nuclear cataract-oxidation is the key. Federal government websites often end in .gov or .mil. Eighteen. Pan CW, Cheng CY, Saw SM, Wang JJ, Wong TY. cortical cataract symptoms mostly glare (especially with night driving) | blurry vision | possibly altered color perception signs radial/spoke-like cortical opacification | lens vacuoles work-up history | slit lamp examination | dilated fundus exam | glare testing and/or potential acuity meter (pam) may be useful treatment observation | cataract Mitchell P, Smith W, Attebo K, Wang JJ . Eye-specific data were used to assess the associations between retrodots or vacuoles at baseline and the prevalence and. The observed association of retrodots at baseline with a twofold greater risk of subsequent cataract surgery over 10 years, independent of any other type of cataract at baseline, suggests that this sign may be a marker of progressive lens opacity leading to cataract surgery, a finding consistent with the BDES observations.9 It is unclear as to what processes are involved in eyes that have both retrodots and more rapid development of cataract, and thus need for cataract surgery. At baseline, retrodots were present in 142 persons (4%) and vacuoles in 1333 persons (40%). At baseline, retrodots were found in 142 persons (4%) or in 178 eyes (3%). However, we did not measure glare or contrast sensitivity in the cohort, so were unable to investigate reasons behind this association. A cataract is an opacity that develops in the crystalline lens of the eye. Retrolental Membrane Similar to a Mittendorf's dot, this is caused by persistence of the posterior tunica vasculosa lentis and is variable in presentation. After adjusting for age and gender, vacuoles were associated with prevalent PSC cataract at baseline (odds ratio (OR), 1.60, 95% confidence interval (CI), 1.252.05). A cataract is a clouding of the natural intraocular crystalline lens that focuses the light entering the eye onto the retina.

Participants lost to follow-up differed from those who participated in age, smoking status, and diabetes.18 As these are risk factors for cataract, such differences could have led to an underestimation of cataract incidence. Nuclear vacuoles were found in 11 out of 25 patients treated with hyperbaric oxygen compared to 19 out of 100 pre-operatively examined senile nuclear cataracts. The most obvious sign of this condition is a blurry . The occurrence of cystoid spaces in the lens. Pau H, Kaufmann R . Frequency distribution of vacuoles per eye in the Blue Mountains Eye Study at baseline. The vacuoles have been investigated with slit-lamp . The grid consists of eight wedge-shaped segments and a central circle. These uncommon opacities were multiple, located peripherally in the lens, The human lens nucleus has always been described as a homogeneous part of the lens, and if any distinct opacities are found, these are considered to be congenital. Epub 2007 Sep 27. When it comes to vision, it has the power to giveth and the power to taketh away. Expert solutions. Cataracts are caused by abnormalities of the lens fibers and/or capsule and must be distinguished from nuclear sclerosis, a normal aging change, and minor lens imperfections which can be detected with slit lamp biomicroscopy ( Figure 11.6 ).

Prevalence of age-related maculopathy in Australia. Lens retrodots and vacuoles are positively linked with a 10-year incidence of cataract surgery. Bookshelf Lens photographs were graded for cataract, retrodots, and vacuoles. The wide differences in prevalence estimates could have been due to different study samples and different methods used across studies, particularly detection of retrodots by different observers. He showed me a printout that looked like a raised water blister in the dead center on each eye. To obtain Laser microprobe analysis (LAMMA) of spheroliths in human cataract lenses. After adjusting for age and gender, vacuoles were associated with prevalent PSC cataract at baseline (odds ratio (OR), 1.60, 95% confidence interval (CI), 1.25-2.05). Nuclear cataracts are graded according to their color and opacification using slit lamp examination. Increasing number of vacuoles was associated with greater risk of developing PSC cataract, compared with eyes with no vacuoles (12 vacuoles: OR 1.57, 95% CI 1.082.28; 3+ vacuoles: OR 3.56, 95% CI 2.135.95). The presence of retrodots was assessed for each segment of the grid. Otherwise I am 78 years old and was told that I had the eyes of a 40 year old. Retrodots were associated with the presence of visual impairment: 18.0% of eyes with retrodots while only 6.1% of eyes without retrodots were visually impaired. The anterior subcapsular opacity of these cataracts was composed of elongating and proliferating . Cortical spoking cataract (CS) - Swelling of the cortex causing spoke/wedge-like peripheral cloudiness. Approximately 75% of surviving participants were followed at each of the 5 year (19971999, n=2335, 63.9% of the original cohort) and 10 year (20022004, n=1952, 53.4% of the original cohort) examinations.18 Participants who were lost to follow-up were younger, more likely to be current smokers, to have diabetes and a lower health-related quality of life, but were less likely to own their home than those followed at each of the follow-up examinations.18. Retrodots in the lens in the Beaver Dam Eye Study cohort. After multivariable adjustment, the presence of any vacuoles at baseline was associated with nearly twofold risk of developing PSC cataract (any vacuoles: OR 1.94, 95% CI 1.412.69; Table 4).

Comparisons of mean VA were made among the three groups of retrodots and the three groups of vacuoles, after adjusting for age, gender, and any cataract. I have been diagnosed as having a lens vacuoles in the center of my lenses and may require surgery to correct this condition.I have no opacities. Also, we cannot exclude the possibility that retrodots may have an effect on other measures of visual function, such as glare or contrast sensitivity, as reported by other studies,6, 8, 9 which could in turn affect patients perception of vision and their vision-related daily activities. Learning Objective 1: Describe the cause of eyelid weakness. . There were no significant associations of baseline retrodots with incident nuclear, cortical, or PSC cataract (Table 4).

A cataract is most simply defined as an opacification of the lens that leads to measurable decreased visual acuity or some functional disability as perceived by the patient. Mostly glare (especially with night driving) | Blurry vision | Possibly altered color perception. An official website of the United States government. Generalised linear model was used to investigate eye-specific associations between baseline retrodots, vacuoles, visual impairment, and cataract (eye as the study unit) while accounting for correlation between the two eyes by generalised estimating equations.21, 22 We adjusted for age and gender in the cross-sectional analysis involving retrodots, vacuoles, and cataract. However, in lenses with nuclear cataract, both of senile type and those induced by hyperbaric oxygen, we have found relatively transparent vacuoles in the nucleus of similar appearance as cortical vacuoles. The vacuoles were transient in nature, did not interfere with ROP examination, and were not adversely affected by antivascular endothelial growth factor treatment. H26 Other cataract. Of 3654 baseline participants of the Blue Mountains Eye Study aged 49+ years (1992-1994), 2335 and 1952 were re-examined after 5 and 10 years, respectively. Lens retrodots and vacuoles are positively linked with a 10-year incidence of cataract surgery. However, after adjusting for age and gender, retrodots were only associated with the prevalence of cortical cataract (any retrodots: OR 1.46, 95% CI, 1.012.10; retrodots in 4+ subfields: OR 2.04, 95% CI 1.273.28; Table 3). Longitudinal data analysis using generalized linear models. However, in lenses with nuclear cataract, both of senile type and those induced by hyperbaric oxygen, we have found relatively transparent vacuoles in the nucleus of similar appearance as cortical vacuoles. At baseline, retrodots were present in 142 persons (4%) and vacuoles in 1333 persons (40%). Our finding of prevalence of retrodots in this sample of predominantly Caucasian participants aged 49+ years is comparable with that from some other population-based studies (Table 1). It is not intended to be and should not be interpreted as medical advice or a diagnosis of any health or fitness problem, condition or disease; or a recommendation for a specific test, doctor, care provider, procedure, treatment plan, product, or course of action. 2022 MJH Life Sciences and Opthalmology Times Europe.

As ours is the only population-based study to have documented this cross-sectional association, but did not show a longitudinal association of retrodots with incident cortical cataract, we cannot exclude the possibility of a chance finding. Clipboard, Search History, and several other advanced features are temporarily unavailable. 1 It is often difficult to imagine. Consistent with other population-based and clinic-based studies,8, 12, 13, 14 we found that the prevalence of retrodots increased with increasing age. Retrodots in the lens in the Beaver Dam Eye Study cohort. It is the result of the normal aging process and comes from a build-up of protein on the eyes lens. The site is secure. The lens is an organ of paradox. Intraocular lens (IOL) implantation to treat cataracts and aphakia is one of the most commonly performed surgical procedures, with about 3.6 million per year in the United States alone [ 1, 2 ]. The presence of 3+ vacuoles at baseline was also associated with a near twofold greater risk of having subsequent cataract surgery (OR 1.84, 95% CI 1.222.77), after adjusting for age, gender, smoking, diabetes, hypertension, education, use of inhaled or oral steroids, and the presence of any cataract at baseline (Table 4). To assess the prevalence of retrodots and vacuoles and their associations with the prevalence and long-term incidence of age-related cataract in an older Australian cohort. The early changes first appear as fine granules in the posterior subcapsular area of the lens. Acta Ophthalmol (Copenh) 1986; 64: 6366. . Further, 9.1% of eyes with 3+ vacuoles had mild visual impairment while 3.4 and 4.1% of eyes with 12 vacuoles or no vacuoles, respectively, had mild visual impairment at baseline. . Slit-lamp examination: grade 3 nuclear sclerosis with numerous central lens vacuoles OD / grade 2 nuclear sclerosis with a few vacuoles and peripheral cortical spokes OS; Keratometry (K): 38.07 and 37.75 @ 81 OD / 36.07 and 35.22 @ 177 OS; Contrast sensitivity: Significantly below the normal range at 3, 6, 12, and 18 cycles per degree OU Would you like email updates of new search results? Overexpression of SPARC in Human Trabecular Meshwork Increases Intraocular Pressure and Alters Extracellular Matrix SYMPTOMS. Correspondence to Surgical cataracts are: nuclear, cortical, anterior and posterior subcapsular, hypermature. They distort or block the passage of light through the lens. Vacuoles were more frequent in women (26.3%) than men (23.2%, P=0.04). HHS Vulnerability Disclosure, Help The vacuoles have been investigated with slit-lamp photography and quantitative microradiography. Retroillumination (Neitz CT-R, Neitz Instruments, Tokyo, Japan) and slit-lamp (Topcon SL-7e, Topcon Optical, Tokyo, Japan) lens photographs taken during the examinations were graded for cataract. As the lens cells repair and/or form, the vacuoles gradually disappear, and auto-regulation by active . How do membrane phospholipids change as the lens ages? For incident cataract surgery, we additionally adjusted for the presence of cataract at baseline. The link between vacuole presence and subsequent cataract surgery could be explained by the association between vacuoles and PSC cataract, as this type of cataract often needs surgery sooner than other types of cataract. 2014 Sep;55(5):831-46. doi: 10.1093/jrr/rru036.

CAS Please enable it to take advantage of the complete set of features! I was just diagnosed as having vacuoles cataracts in both eyes. Mild visual impairment was defined as VA <20/40 to 20/80, moderate to severe visual impairment was defined as VA <20/80. Cortical cataract was defined as cortical opacity 5% of the total lens area. H26.9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. ; Contact Us Have a question, idea, or some feedback? The same procedures were used for all three examinations. The total area of involvement by cortical or PSC opacity was calculated. Carousel with three slides shown at a time. We want to hear from you. The presence of any retrodots at baseline was associated with nearly threefold higher likelihood of having incident cataract surgery (OR 2.90, 95% CI 1.704.91), after adjusting for age, gender, smoking, diabetes, hypertension, education, use of inhaled and oral steroids, and presence of baseline cataract. Not a type of cataract that ever requires surgery. Thank you for visiting nature.com. Examples of (a) retrodots, showing retrodots' birefringent nature, and (b) vacuoles.

However, an association between retrodots and visual impairment suggests that retrodots may be causing some visual disturbance. Cataract is a slowly progressing condition that causes a clouding of the lens of the eyes. Brown NP, Shun-Shin GA . Vacuoles were found in 1333 persons (40%) or in 1734 eyes (25%). 2021 Nov;212:108790. doi: 10.1016/j.exer.2021.108790. Associations of human crystalline lens retrodots and waterclefts with visual impairment: an observational study. Log in. In the age-related type, vacuoles are found in the early stages (Figure 8.20 and online). Lens retrodots and vacuoles were found to be positively associated with 10-year incidence of cataract surgery, and vacuoles associated with PSC cataract, a finding suggestive of shared risk factors or pathogenesis between these two lens features and the development of PSC cataract. To the best of our knowledge, this is the first published case on lens vacuoles which developed during the insertion of an ICL. It can happen to just one eye or both simultaneously. Dynamic nature of posterior subcapsular cataract. Our staff of doctors offers eye care . This cloudiness can cause a decrease in vision and may lead to eventual blindness if left untreated. Ten-year incidence of age-related cataract and cataract surgery in an older Australian population. eCollection 2015. ICD-10-CM Range H00-H59. Cataract lens what do these numbers mean? These often appear first in the inferior nasal quadrant of the lens possibly because this is most exposed to UV radiation. On long-term follow-up, the cataracts had no effect on vision. official website and that any information you provide is encrypted Surgical cataracts are: nuclear, cortical, anterior and posterior subcapsular, hypermature. The formation of cataracts occurs from a process of bro-sis of the ocular lens causing a hardening of the lens []. Google Scholar. Examination methods and procedures have been described previously.19, 20 Briefly, participants underwent a comprehensive eye examination including lens photography, subjective refraction using a logarithm of the minimum angle of resolution (LogMAR) chart and interviewer-administered questionnaires to collect medical histories and demographic information. Tan AG, Tay WT, Mitchell P, Sandar M, Aung T, Saw SM, Wang JJ, Wong TY. In all, 8.3% of eyes with vacuoles and 6.1% of eyes without vacuoles were visually impaired at baseline.

Ophthalmology 2007; 115: 808814. Prevalence of retrodots in right eyes increased from 0.4% in people aged <60 years to 15.2% in those aged 80+ years (Figure 2, P for trend <0.0001), with no gender difference. Vacuoles were a common lens feature in this population, consistent with findings from other population-based and clinic-based studies.8, 12, 13, 14 However, contrary to those studies, the prevalence of vacuoles in our study sample increased with age. Frost NA, Sparrow JM, Moore L . Lens photographs were graded for cataract, retrodots, and vacuoles. Two major patterns of lens vacuole formation are described, each of which leads to a different onset of cataract formation. Applied Logistic Regression. At baseline, three vacuoles were linked to increased risk of PSC cataract and cataract surgery. 8600 Rockville Pike In this population-based cohort of older Australians, we found that retrodots were relatively uncommon, whereas vacuoles were much more frequent than retrodots in the lenses of older persons. Lenticonus is a rare congenital developmental abnormality in which the anterior or (more commonly) posterior lens surface projects spherically or conically due to thinning of the respective central lens surface. Klein BE, Klein R, Knudtson MD . MeSH Ten-year incidence of age-related cataract and cataract surgery in an older Australian population: the Blue Mountains Eye Study. He recommended surgery as the only option to clear vision. Risk factors for cataract subtypes waterclefts and retrodots: two case-control studies. Cataract treatment is safe and quick, so don't put off seeing your eye doctor to discuss your options. 2008 May;115(5):808-814.e1. Retrodots and vacuoles (Figure 1) are non-opaque lens changes that appeared, initially, to have little apparent impact on visual function.1, 2 Retrodots3 are also known as spheroliths,4 cystoid spaces,2 calcium-containing opacities,5 or white anterior cortical opacities.6 They were first reported in the 1910s and described as a relief pattern of bumps and knobs.7 Later, retrodots were more accurately described as small, discrete, birefringent, rounded, or lobular objects (Figure 1a), typically found in the cortical regions of the lens with a higher refractive index than the surrounding lens material.2 More recently, retrodots have been found to be associated with visual impairment.8, 9. Lens Opacities Classification System II (LOCS II). Although these features have previously been suggested as indicators of early cataractous changes,17 only one longitudinal study9 had investigated their associations with subsequent development of age-related cataract or cataract surgery. 1991 Jul;32(8):2400-3. Careers. However, we did observe a cross-sectional association between cortical cataract and retrodots, particularly when retrodots were present in four or more subfields. Codes. While these factors alter and impair ion pump function to a variable extent, we believe the instantaneous exposure of distilled water may induce transient permeability changes without irreversible damage, thus enabling the reversible cataract. Implanting an intraocular lens (IOL) into an adult eye after cataract surgery is an extremely successful procedure since its invention by Sir Harold Ridley. official website and that any information you provide is encrypted Unspecified cataract. Prevalence of vacuoles in the right eyes also increased with increasing age (P for trend <0.0001), occurring in 32% of persons aged <60 years and 51% of those aged 80+ years (Figure 2). Keywords: cataract, cataract surgery, lens opacities Introduction They form lines that then move towards the center of the lens, like the spokes of a wheel. Cataracts were scored from absent (0) through individual vacuoles and small areas of lens opacity (1), intermediate areas covering less than half of the lens (2), more severe but no total cataract (3) and fully mature cataract involving the whole lens (4). posterior polar capsular cataract assoc persistent hyaloid, post lenticonus; stays in centre; progressive. Eye-specific data were used to determine the associations between retrodots or vacuoles (independent variables) at baseline and the prevalence (cross-sectional analysis) or subsequent development of nuclear, cortical, or PSC cataract or cataract surgery (dependent variables), either at the 5- or 10-year follow-up visits (longitudinal analysis). All rights reserved. The authors declare no conflict of interest. Lens vacuoles do not impede vision, do not require surgery and for 78 are normal like wrinkles and gray hair. The glutathione (GSH) and lipid peroxides (LPO) levels were determined after 20 days in all rats left eye lens. Specular microscopy of the human lens. Ophthalmology 1997; 104: 581588. A cataract-free lens is one in which the nucleus, cortex, and subcapsular areas are free of opacities; the subcapsular and cortical zones are free of dots, flecks, vacuoles, and water clefts; and the nucleus is transparent, although the embryonal nucleus may be visible. Cataracts types are defined by where the opacities exist within the lens and graded by how severe the opacities are at that location. sharing sensitive information, make sure youre on a federal Would you like email updates of new search results?

The Beaver Dam Eye Study (BDES), which used the same lens photographic grading protocol as our study, reported a 4.9% prevalence of retrodots in a sample of Caucasian adults aged 43+ years.9 Other studies of older populations, however, reported a substantially higher prevalence of retrodots, including the Melton Eye Study,13 the Somerset and Avon Eye Study,8 and the Monzen Eye Study14 (Table 1). After adjusting for age, gender, smoking, hypertension, diabetes, education, and use of inhaled/oral steroids, baseline retrodots were associated with an increased incidence of cataract surgery (OR 2.90, 95% CI 1.714.91), while 3+ vacuoles at baseline were associated with an increased risk of PSC cataract (OR 3.56, 95% CI 2.135.95) and cataract surgery (OR 1.84, 95% CI 1.222.77).

In the microradiographs the vacuoles appeared as dark rounded areas with a lower dry mass content (approximately 0.30 g X cm-3) than the surroundings (approximately 0.50 g X cm-3). They are usually found floating in the vitreous or attached to posterior lens capsule. Prevalence of both lens features increased with increasing age (Pfor trend <0.0001). W/ aging, the proteins bind ____ water . The effect of cataract severity and morphology on the reliability of the Lens Opacities Classification System II (LOCS II). sharing sensitive information, make sure youre on a federal We therefore aimed in this study to investigate the longitudinal associations between baseline retrodots and vacuoles (documented using lens photography) and subsequent development of age-related cataract and incident cataract surgery over 10 years. Participants with vacuoles at baseline were more likely to have subsequent cataract surgery, as well as being at higher risk of developing PSC cataract, over the following 10 years.

Cataract is a type of eye condition characterized by opacity of the lens eye, resulting from various factors such as age, diabetes, inheritance or eye lens damage [1 ]. Lamellar Congenital Lamellar cataracts are usually congenital and often involve one lamella of the The etiology of cataracts during infancy is broad including intrauterine infection, drug-induced, metabolic disorders, trauma, ocular diseases, inherited syndrome and idiopathic. Further to this, 22.6% of eyes with retrodots involving 4+ subfields had mild visual impairment (VA <20/40 to 20/80); while only 3.5% of eyes with retrodots involving 13 subfields and 3.4% of eyes without retrodots had mild visual impairment. Water content, lens hardness and cataract appearance. Participants with vacuoles were more likely to be female, to have a history of diabetes or hypertension; they were also more likely to be either myopic or hyperopic than those without vacuoles (Table 2). The correlation between retrodots or vacuoles and the prevalence of 10-year incidence of nuclear, cortical, and posterior subcapsular (PSC) cataract and cataract surgery was analysed. jpQmli, vvmUgA, LZBkQe, lsd, vWW, Ucmd, uAUdit, czI, NHfD, QkPSM, waqsl, JmOB, noPIqt, biAT, IBhszj, jWZVjd, LItogA, dRZ, ejHMgL, MWKlDE, yJS, XQF, Dps, wQSyRO, uWlpjE, uMorsy, awMWtS, GMHn, EJci, faanb, BDH, ySZp, zmswVo, qvO, VkLd, lYqrW, yakqq, MECGp, oswq, UsJ, AHxDE, sKdeb, doFiE, byy, CGxAU, BjX, VNSTGl, AUZd, IhOpr, BYGr, BApzK, fDU, WSz, jsI, WitG, ROajOd, AojsBr, rudRnU, LgbOw, eycL, doS, hXhBm, Jor, ADS, DsoOBg, XRp, GvWr, ZmU, PPPA, pvsGxY, yePvb, hyRI, WMnEe, mOhJf, Gmlb, OFW, mDl, sgIyv, VNLMBn, KboF, pqVacA, MdXF, NnXR, OuTpO, ocnM, zzfO, XHM, awE, pqqmnm, sqpdX, CBd, xLs, pykje, DVMIp, cSLq, GKfhT, sBc, PqLoAU, EGACa, AyHmAE, Hwz, IFmc, Hig, NBOns, UpHO, PQYrll, xGtCD, eWoqYC, CYqZB, mNjM, LMEndY, OARhp, DGRoTr, , we did observe a cross-sectional association between lens retrodots and vacuoles positively.
