Randomised clinical trial of lensectomy versus lens aspiration and primary capsulotomy for children with bilateral cataract in south India. (1/85)

AIMS: The primary objective was to determine which surgical technique gave the best long term visual outcome for infants and young children with bilateral symmetrical cataract in south India. Secondary objectives were to assess complications and the need for further surgical intervention. METHODS: A randomised controlled clinical trial was undertaken. 65 children under 10 years old with bilateral cataract had one eye treated by lensectomy and the other by aspiration with primary capsulotomy. RESULTS: 56 children (86%) with a mean age at surgery of 53 months were reviewed 3 years after surgery. The overall binocular acuity was 6/18 or better in 57.1% and 6/60 or better in 94.6%. There was no difference in visual acuity between the matched pairs of eyes undergoing aspiration or lensectomy at the third year of follow up (p=0.57). Aspiration eyes were more likely to require a secondary procedure to restore vision than lensectomy eyes (66.1% v 1.8%). CONCLUSION: Aspiration with primary capsulotomy gives an acceptable visual outcome in this part of India providing that there is good follow up to manage capsule opacification. If secondary intervention is not possible owing to poor compliance with follow up, then lensectomy is likely to give better long term visual rehabilitation providing there is good maintenance and technical support for the lensectomy equipment.  (+info)

Diabetic versus non-diabetic colour vision after cataract surgery. (2/85)

AIMS: To examine whether the colour vision abnormalities found in phakic patients with diabetes mellitus is preserved after removal of the lens by cataract surgery. METHODS: 21 diabetic (16 IDDM and five NIDDM) and 19 non-diabetic patients of comparable age, postoperative visual acuity, and sex distribution, all aphakic or pseudophakic following cataract surgery, had their monocular colour vision examined using the Farnsworth-Munsell 100 hue test. The fundus status of the diabetic patients ranged from no retinopathy to photocoagulation treated proliferative diabetic retinopathy. Patients with macular oedema were specifically excluded from the study. RESULTS: The error scores of both the diabetic (mean 146 (SD 94)) and the non-diabetic patients (83 (79)) did not deviate significantly from the age related normal range. The error score in the diabetic group was significantly higher than in the non-diabetic group (p=0.02) but the amplitude of the difference was small in comparison with previous studies of phakic subjects. The error scores in the diabetic group were not correlated with the degree of retinopathy (p>0.2). CONCLUSION: After cataract surgery only a minor difference exists between the colour vision scores of diabetic and non-diabetic patients. This indicates that accelerated yellowing of the lens in diabetes is the predominant cause of the colour vision anomaly found in phakic diabetic patients.  (+info)

Deletion in the promoter region and altered expression of Pitx3 homeobox gene in aphakia mice. (3/85)

Mouse aphakia (ak) is a recessive phenotype that spontaneously occurs in the 129/Sv-SlJ strain and is characterized by small eyes that lack a lens. We have recently identified a homeobox-containing gene, Pitx3, and have shown that it is expressed in the developing lens and maps to chromosome 19 close to ak in mouse. Human PITX3 gene was found to underlie anterior segment dysgenesis and cataracts. We have now obtained the entire sequence of the mouse Pitx3 gene including 10 kb of the 5' region and 5 kb of the 3' region. Of several microsatellite repeat regions identified within the Pitx3 sequence, one was informative for linkage analysis. No recombination was observed between ak and the Pitx3 marker, indicating that these two loci are closely linked (0.2 +/- 0.2 cM). Additionally, Pitx3 transcripts were not detected in the ak/ak mice either in the lens placode or at later developmental stages of the lens by in situ hybridization. Since no differences were previously found between ak/ak and wild-type sequences in the Pitx3 coding region, we hypothesized that an etiologic mutation is located in the promoter or other regulatory regions. To test this hypothesis we studied the 5' flanking region of the Pitx3 gene. This analysis revealed a deletion of 652 bp located 2.5 kb upstream from the start point of the Pitx3 5' UTR sequence in ak/ak mice. The deletion co-segregated with the ak mutation and was not detected in 16 samples from 10 different mouse strains including the founder strains. Analysis of the 652 bp region identified sequences similar to consensus binding sites for transcription factors AP-2 and Maf that were shown to play a critical role in lens determination. These lines of evidence suggest that the abnormal ocular development in the aphakia mouse is due to the deletion upstream of the Pitx3 gene.  (+info)

Pitx3 is required for development of substantia nigra dopaminergic neurons. (4/85)

Dopaminergic (DA) neurons of substantia nigra in the midbrain control voluntary movement, and their degeneration is the cause of Parkinson's disease. The complete set of genes required to specifically determine the development of midbrain DA subgroups is not known yet. We report here that mice lacking the bicoid-related homeoprotein Pitx3 fail to develop DA neurons of the substantia nigra. Other mesencephalic DA neurons of the ventral tegmental area and retrorubral field are unaltered in their dopamine expression and histological organization. These data suggest that Pitx3-dependent gene expression is specifically required for the differentiation of DA progenitors within the mesencephalic DA system.  (+info)

Pitx3 is required for motor activity and for survival of a subset of midbrain dopaminergic neurons. (5/85)

Mesencephalic dopaminergic (MesDA) neurons play crucial roles in motor and behavioral processes; their loss in Parkinson's disease (PD) results in striatal dopamine (DA) deficiency and hypokinetic movement disorder. The Pitx3 homeobox gene is expressed in the MesDA system. We now show that only a subset of MesDA neurons express Pitx3 and that in Pitx3-deficient aphakia mice, this subset is progressively lost by apoptosis during fetal (substantia nigra, SN) and postnatal (ventral tegmental area) development, resulting in very low striatal DA and akinesia. Similar to human PD, dorsal SN neurons (which are Pitx3 negative) are spared in mutant mice. Thus, Pitx3 defines a pathway for survival of neurons that are implicated in PD and that are required for spontaneous locomotor activity.  (+info)

Early developmental failure of substantia nigra dopamine neurons in mice lacking the homeodomain gene Pitx3. (6/85)

The mesencephalic dopamine (mesDA) system is involved in the control of movement and behavior. The expression of Pitx3 in the brain is restricted to the mesDA system and the gene is induced relatively late, at E11.5, a time when tyrosine hydroxylase (Th) gene expression is initiated. We show here that, in the Pitx3-deficient aphakia (ak) mouse mutant, the mesDA system is malformed. Owing to the developmental failure of mesDA neurons in the lateral field of the midbrain, mesDA neurons are not found in the SNc and the projections to the caudate putamen are selectively lost. However, Pitx3 is expressed in all mesDA neurons in control animals. Therefore, mesDA neurons react specifically to the loss of Pitx3. Defects of motor control where not seen in the ak mice, suggesting that other neuronal systems compensate for the absence of the nigrostriatal pathway. However, an overall lower activity was observed. The results suggest that Pitx3 is specifically required for the formation of the SNc subfield at the onset of dopaminergic neuron differentiation.  (+info)

Cataract surgical coverage and outcome in the Tibet Autonomous Region of China. (7/85)

BACKGROUND: A recently published, population based survey of the Tibet Autonomous Region (TAR) of China reported on low vision, blindness, and blinding conditions. This paper presents detailed findings from that survey regarding cataract, including prevalence, cataract surgical coverage, surgical outcome, and barriers to use of services. METHODS: The Tibet Eye Care Assessment (TECA) was a prevalence survey of people from randomly selected households from three of the seven provinces of the TAR (Lhoka, Nakchu, and Lingzhr), representing its three main environmental regions. The survey, conducted in 1999 and 2000, assessed visual acuity, cause of vision loss, and eye care services. RESULTS: Among the 15,900 people enumerated, 12,644 were examined (79.6%). Cataract prevalence was 5.2% and 13.8%, for the total population, and those over age 50, respectively. Cataract surgical coverage (vision <6/60) for people age 50 and older (85-90% of cataract blind) was 56% overall, 70% for men and 47% for women. The most common barriers to use of cataract surgical services were distance and cost. In the 216 eyes with cataract surgery, 60% were aphakic and 40% were pseudophakic. Pseudophakic surgery left 19% of eyes blind (<6/60) and an additional 20% of eyes with poor vision (6/24-6/60). Aphakic surgery left 24% of eyes blind and an additional 21% of eyes with poor vision. Even though more women remained blind than men, 28% versus 18% respectively, the different was not statistically significant (p = 0.25). CONCLUSIONS: Cataract surgical coverage was remarkably high despite the difficulty of providing services to such an isolated and sparse population. Cataract surgical outcome was poor for both aphakic and pseudophakic surgery. Two main priorities are improving cataract surgical quality and cataract surgical coverage, particularly for women.  (+info)

Neonatal aphakia retards ocular growth and alters scleral gene expression in rhesus monkeys. (8/85)

PURPOSE: We hypothesize that remodeling of the scleral extracellular matrix, involving collagen and proteoglycan synthesis and turnover, is a key process involved in ocular growth. Decreased axial elongation is observed following neonatal removal of the crystalline lens in a rhesus monkey model of congenital cataract. We wanted to determine changes in gene expression in the operated and companion eye following lensectomy, especially for extracellular matrix in the sclera. METHODS: Between 4 and 7 days of age, infant monkeys underwent surgical removal of the lens from the right eye. Axial lengths of the operated and unmanipulated fellow eyes were measured and when interocular differences of >0.4 mm were achieved, monkeys were sacrificed and RNA was isolated from sclera. In order to determine changes in scleral gene expression in aphakic versus control eyes, we used Clontech's Atlas Gene Array (Human Cancer Array version 1.2) hybridized with total RNA from three monkeys. RESULTS: Atlas Gene Array analysis demonstrated differential expression of several genes in the operated versus the unmanipulated eye. Most notably, there was a statistically significant increase in expression of several extracellular matrix (ECM) genes including: aggrecan, decorin, biglycan, several collagens, and tenascin in the RNA from the sclera of the aphakic eyes when compared to the unmanipulated eyes. Genes for several matrix metalloproteinases (MMPs) showed no significant change following lens removal although there was a trend towards decreased expression. There were also statistically significant changes in the pattern of gene expression in the operated eye relative to the unmanipulated eye for cell adhesion, cell cycle, apoptosis, and cytoskeleton transcripts. CONCLUSIONS: Our results suggest that removal of the crystalline lens alters gene expression in the sclera with a prominent upregulation of ECM transcripts. These data support recent evidence that remodeling of the ECM composition of the sclera may be an important regulator of ocular growth.  (+info)

Aphakia is the absence of the lens of the eye, due to surgical removal, a perforating wound or ulcer, or congenital anomaly. It causes a loss of accommodation, far sightedness (hyperopia), and a deep anterior chamber. Complications include detachment of the vitreous or retina, and glaucoma. Babies are rarely born with aphakia. Occurrence most often results from surgery to remove congenital cataract (clouding of the eyes lens, which can block light from entering the eye and focusing clearly). Congenital cataracts usually develop as a result of infection of the fetus or genetic reasons. It is often difficult to identify the exact cause of these cataracts, especially if only one eye is affected. People with aphakia have relatively small pupils and their pupils dilate to a lesser degree. Without the focusing power of the lens, the eye becomes very farsighted. This can be corrected by wearing glasses, contact lenses, or by implant of an artificial lens. Artificial lenses are described as ...
Posterior capsular rupture is a relatively rare complication, occurring in 0.9% of patients undergoing cataract surgery.7 Postsurgical aphakia and traumatic and nontraumatic dislocation of the IOL continue to be challenges for ophthalmologists when surgical correction is intended.8,9. Different techniques and lens designs exist for the management of aphakia without capsular support. Anterior chamber IOLs, scleral-sutured lenses, posterior chamber iris-sutured IOLs, and anterior and posterior chamber iris-fixated IOLs are the most widely used.2,4,8,10. Anterior chamber IOLs are technically simple to place, but they are associated with a considerable risk of trabecular damage, secondary glaucoma, and corneal decompensation.9 The currently used open-loop anterior chamber IOLs have lowered these complications, but a preoperative endothelial cell count and a measurement of anterior chamber depth are mandatory.10-12. In 2000, Zeh and Price described a technique for posterior chamber iris IOL ...
PURPOSE: To evaluate the indications, postoperative visual efficacy, and complication rate after intraocular implantation of an iris-claw aphakic intraocular lens (IOL). SETTING: Oxford Eye Hospital, Oxford, United Kingdom. DESIGN: Case series. METHODS: This chart review comprised eyes with no capsule support that had anterior iris-fixation IOL implantation for aphakia between 2001 and 2009. RESULTS: The study comprised 116 eyes (104 patients). Iris-claw IOLs were inserted during primary lens surgery in 18 eyes (15.5%), during an IOL exchange procedure for dislocated posterior chamber IOLs in 19 eyes (16.4%), and as a secondary procedure in 79 eyes (68.1%). The mean follow-up was 22.4 months (range 3 to 79 months). The final corrected distance visual acuity (CDVA) was 6/12 or better in 68.9% of all eyes and in 47 of 53 eyes (88.7%) with no preoperative comorbidity. Complications included wound leak requiring resuturing in 2.6% of eyes, postoperative intraocular pressure rise in 9.5% of eyes (glaucoma
The Infant Aphakia Treatment Study evaluated outcomes after unilateral cataract surgery during early infancy in children randomly assigned to primary aphakic correction with an IOL or contact lens. Visual acuity results and clinical findings during follow-up through age 5 were recently published.
A total of 12 eyes of 10 consecutive patients were included. Mean age at surgery was 10 ± 6 years. Indications for scleral fixation were ectopia lentis (secondary to Marfan syndrome [n = 3] or idiopathic [n = 1]), lens subluxation with intermittent pupillary block secondary to Weill- Marchesani syndrome (n = 2), early childhood lensectomy with insufficient residual capsular support (n = 5), and traumatic aphakia after an open globe (n = 1). Mean follow-up was 8 ± 5 months. No major intraoperative complications occurred. Postoperatively 1 patient required IOL repositioning 1 week after surgery. The location of one haptic was noted to be intrascleral but superficial in another patient, who did not require surgical intervention. The mean postoperative astigmatism was 2 ± 2 D. Good visual results were achieved in all eyes ...

It would be ideal to have the ability to monitor adherence to occlusion from the time of surgery through the assessment of grating acuity. Therefore, another limitation of these analyses was the maximum of three assessments of adherence, and the variation in number of assessments because of differences in age at surgery and because caregivers did not complete all scheduled assessments. The analyses were limited to participants with at least two adherence assessments and to the first three assessments because grating visual acuity had been assessed for the majority of participants by 9 months after surgery. An additional concern was related to the summary definitions of adherence that were chosen. The primary measure of adherence was the mean percentage of prescribed patching reported by caregivers at the three time points. This measure was weighted towards the early months after surgery since two of the time points were obtained in the first 3 months after surgery. The proportion of caregivers ...

The glaucoma fellowship of the Farabi Eye Hospital and Tehran University of Medical Sciences has been established since 1995, and it is aimed to provide comprehensive training in the diagnosis and medical and surgical management of both routine glaucoma patients as well as complicated glaucoma cases commonly referred to tertiary centers such as ours.
Purpose: The Infant Aphakia Treatment study showed that infants with unilateral cataracts that were removed with intraocular lens (IOLs) implanted had significantly more postoperative adverse events and additional surgeries, often due to visual axis opacification. We previously demonstrated that 10mg of Enoxaparin, a low molecular weight heparin, showed a significant improvement in optical clarity after lensectomy in a juvenile model of lensectomy with aphakia. To test the hypothesis that postoperative inflammation and fibrosis can also be reduced even with IOL insertion, we tested the safety of candidate interventions to prevent postoperative fibrosis and inflammation.. Methods: All experiments were approved and in compliance with Animal Care Committee at the University of Illinois at Chicago. Juvenile (6-7 week old) New Zealand White rabbits (Harlan) had lensectomy with IOL insertion under general anesthesia with ketamine and xylazine. Clear-cornea lens extraction surgery was performed with ...

So happy you have the resources for relaxed choices after the court case and the opportunity to work with Dr V with your best interests at heart. Good to hear they are innovating with BSL in 7m. Would they use bandage lens for you post-op or is it entirely steroid control? I was wondering if he thought the capsule is more fragile than normal? And curious where he recommends for tied IOL for the other eye? I notice he says theres a high incidence of glaucoma post-IOL in aphakic eye and wonder whether he can look after you post-op if you go for that elsewhere ...

For people using 30-day extended-wear/continuous-wear (EW/CW) contact lenses, replacing lenses at night doesnt lower the risk of complications compared to changing lenses monthly, suggests a study -
In three eyes which underwent cataract extraction no evidence of senile pseudoexfoliation was found either before, or immediately after, surgery in spite of repeated biomicroscopical examination under full mydriasis. Years later pseudoexfoliative material was found on the anterior hyaloid and on the pupillary border. In another case, wherein the lens was traumatically dislocated and had lain in the inferior vitreous chamber for 53 years, pseudoexfoliative material was present on the anterior hyaloid, but not in the vitreous. Collating these clinical observations with data from electron and light microscopy studies, the authors refute the assumption that lens epithelium is the source of pseudoexfoliative material. ...
SO takes a spherical form in the posterior chamber of aphakic eyes and does not enter the anterior chamber. In presence of pupillary block, the aqueous accumulates in the lower part of the posterior chamber. Aqueous pressure thus builds up in the posterior chamber and forces SO through the pupil into the anterior chamber which may block the outflow from the angles.(Figure 2,3) A PI at 6-oclock usually solves this problem but it is seen that despite a patent PI, forward migration of the oil was found in 11%. This could be due to several reasons - improper size, improper location, low aqueous turnover, occurrence of choroidal detachment that decreases the volume of the vitreous cavity. It is usually difficult to detect the presence of oil in oil filled anterior and posterior chambers since the oil is transparent and is like a single large globule occupying the chambers. One way of detecting presence of oil is by seeing the cells in the chamber which have become stagnant. Oil in the anterior ...

Glaucoma - Plastic and reconstructive surgery offers other important therapies for specialists treating patients with complicated glaucoma. Filtering surgery, for example, reduces pressure within the eye, but usually creates a bleb (blister) on the eyes surface. If this bleb is exposed, the eye is at risk of serious infection. If the bleb is large, it can affect the eyelids function. In either case, surgical adjustment of the eyelid allows it to function well and protects the bleb -- without affecting the pressure control benefit of filtering surgery itself. In cases of end-stage glaucoma, or old trauma, there can be complete loss of sight and excessive pain. To relieve the pain, oculoplastic surgeons often remove the eye (enucleation) and place an orbital implant. Approximately five weeks later, a custom-made ocular prosthesis is made by an ocularist. This artificial eye will restore a more normal appearance and relieve discomfort.. Lacrimal Drainage System Problems - Some patients ...
Physiological monitoring can be provided through a syncope sensor (64, 66) embedded into an electrocardiography monitor (12), which correlates syncope events and electrocardiographic data. Physiological monitoring can be provided through a lightweight wearable monitor (12) that includes two components: a flexible extended-wear electrode patch (15) and a reusable monitor recorder (14) that removably snaps into a receptacle (25) on the electrode patch (15). The wearable monitor (12) sits centrally on the patients sternal midline (16) and includes a unique narrow hourglass-like shape, significantly improving the ability of the monitor to cutaneously sense cardiac electrical potential signals, particularly the P-wave and QRS interval signals. The electrocardiographic electrodes (38, 39) on the electrode patch (15) are tailored for axial positioning along the midline (16) of the sternum (13) to capture action potential propagation in an orientation that corresponds to the aVF lead in a conventional 12
Lens removal during MH repair offers several advantages. First, lensectomy eliminates the need for an otherwise inevitable second surgical intervention for a post-vitrectomy cataract extraction (CE) especially given that in the Vitrectomy for Macular Hole Study, the incidence of nuclear sclerosis progression following vitrectomy was 100 percent at 2 years follow-up.(40) Second, early lensectomy avoids the direct surgical challenges associated with delayed CE in vitrectomized eyes.(41-43) Third, avoiding delayed CE following MH repair may help decrease the rate of hole reopening, since delayed CE itself has been implicated as a possible factor in late MH reopening in several studies.(40,44-46) These studies suggest that delayed CE may play a role in late MH reopening; however, the rate of MH reopening of 8.5 percent observed in our study was similar to that noted in the major report by the American Academy of Ophthalmology, which varied between 2 to 10 percent.(47) Fourth, lensectomy virtually ...

Although other application methods are also acceptable, the ideal way to apply Vivilon restorer is to spray it on. This achieves speed and the finest finish. Its synthetic moisturizing molecules penetrate into and completely encapsulate weather-damaged pigments with image enhancers to guarantee exact original-color restoration. As it quickly air dries, Vivilons blend of extended-wear acrylic and nylon resins microbond with the existing surface to create maximum adhesion. Within minutes, an impermeable, virtually maintenance-free weather barrier is created that is guaranteed not to crack, peel, discolor or lose its gloss for a minimum of five years. However, actual exterior-exposure durability often exceeds 10 years. And, even then, whenever it starts to fade, it is easily reapplied after a quick cleaning for additional years of carefree service. Application can be done by in-house maintenance personnel with factory technical support or by Vivilon certified contractors. Vivilon can offer this ...
Joss Whedons The Avengers has drawn criticism from several Bollywood stars dismayed over the depiction of India in the superhero blockbuster.. The star-studded Marvel epic opens with scenes in which Hulks alter ego Dr. Bruce Banner, played by Mark Ruffalo, hides in the slums of Calcutta curing lepers.. The film has opened well in the country but some members of Indias film industry have expressed disappointment that the scenes, which were actually shot in New Mexico, zeroed in on squalor.. Actor Rituparna Sengupta tells The Hindustan Times, Calcutta has a rich culture and heritage, and a filmmaker should respect that. There are two scenes about India, and they only show slums. It could have been done in better taste.. Bollywood actress Neha Dhupia adds, It is disturbing to see the murky underbelly of India in Hollywood films. But before pointing it out to the West, we need to make efforts to change their perception about us.. ...
Myopic shift occurs most rapidly in the first 1.5 years of life after IOL implantation in infancy, reported David R. Weakley, Jr., MD, and fellow researchers. They were focused on a myopic shift at age 5 after cataract surgery with IOL implantation for infants in the Infant Aphakia Treatment Study. Researchers performed refractions at 1 month and at every 3 months until age 4, and then at 4.25, 4.5, and 5 years of age. Of 43 eyes that were analyzed, the mean rate of myopic direction change from 1 month after surgery to age 1.5 years was 0.35 D; after age 1.5 years, the mean rate of myopic direction change was 0.97 D per year. In children who had surgery at age 1 month and were age 5 at the time of the study, the mean refractive change was 8.97 D. The mean refractive error at age 5 was -2.53 D. If the goal is emmetropia at age 5 years, then the immediate postoperative hypermetropic targets should be +10.5 D at 4 to 6 weeks and +8.50 D from 7 weeks to 6 months, the researchers concluded. ...

Many different bacteria and viruses can cause conjunctivitis in the neonate. The two most common causes are N. gonorrheae and Chlamydia acquired from the birth canal during delivery. Ophthalmia neonatorum due to gonococci (Neisseria gonorrhoeae) typically manifests in the first five days post birth and is associated with marked bilateral purulent discharge and local inflammation. In contrast, conjunctivitis secondary to infection with chlamydia (Chlamydia trachomatis) produces conjunctivitis after day three post birth, but may occur up to two weeks after delivery. The discharge is usually more watery in nature (mucopurulent) and less inflamed. Babies infected with chlamydia may develop pneumonitis (chest infection) at a later stage (range 2 weeks - 19 weeks after delivery). Infants with chlamydia pneumonitis should be treated with oral erythromycin for 10-14 days.[6] Other agents causing ophthalmia neonatorum include Herpes simplex virus (HSV 2), Staphylococcus aureus, Streptococcus ...
A distichia is an eyelash that arises from an abnormal spot on the eyelid. This abnormality, attributed to a genetic mutation, is known to affect dogs and humans. Distichiae (the abnormal eyelash) usually exit from the duct of the meibomian gland at the eyelid margin. They are usually multiple and sometimes more than one arises from a duct. They can affect either the upper or lower eyelid and are usually bilateral. The lower eyelids of dogs usually have no eyelashes.[1] Distichiae usually cause no symptoms because the lashes are soft, but they can irritate the eye and cause tearing, squinting, inflammation, corneal ulcers and scarring.[2] Treatment options include manual removal, electrolysis, electrocautery, cryotherapy, and surgery. ...
Diagnosis can be established on clinical grounds and this may be enhanced with studies on surgically excised corneal tissue and in some cases with molecular genetic analyses. As clinical manifestations widely vary with the different entities, corneal dystrophies should be suspected when corneal transparency is lost or corneal opacities occur spontaneously, particularly in both corneas, and especially in the presence of a positive family history or in the offspring of consanguineous parents.. Superficial corneal dystrophies - Meesmann dystrophy is characterized by distinct tiny bubble-like, punctate opacities that form in the central corneal epithelium and to a lesser extent in the peripheral cornea of both eyes during infancy that persists throughout life. Symmetrical reticular opacities form in the superficial central cornea of both eyes at about 4-5 years of age in Reis-Bücklers corneal dystrophy. Patient remains asymptomatic until epithelial erosions precipitate acute episodes of ocular ...
