Visual outcome after contact lens and intraocular lens correction of neonatal monocular aphakia in monkeys. (1/91)

PURPOSE: A monkey model was used to evaluate intraocular lenses (IOLs) and extended-wear contact lenses (EWCLs) for the optical treatment of infantile aphakia in humans. Specifically, the relative effectiveness of EWCLs used alone and IOLs used in combination with EWCLs in preventing amblyopia was assessed. METHODS: A total of 33 rhesus monkeys was studied in this project, 24 assigned to experimental treatment groups and 9 to normal controls. Contact lenses made from a diffusing material or dyed opaque were placed on one eye at birth to simulate an infantile cataract. A unilateral lensectomy was then performed on the same eye within 2.5 weeks after birth. In 15 monkeys this was combined with implantation of an IOL. The eyes were left aphakic in the remaining 9 animals. EWCLs were used to adjust the optical correction of both aphakic and pseudophakic eyes to a near point (3-5 D). Opaque lenses were used to maintain daily part-time (approximately 70%) occlusion of the fellow eye. The primary outcome measure was grating acuity assessed with behavioral methods. Some animals were also assessed for acuity with sweep visually evoked potentials (VEPs) and for optotype acuity (Landolt C) with behavioral methods. RESULTS: Two of the animals with IOLs developed complications in the eye that precluded completion of the behavioral assessment protocol. Only behavioral outcomes obtained before or in the absence of surgical complications are presented. There was a developmental delay in the maturation of grating acuity in both eyes of both treatment groups. Normal adult levels of grating acuity were eventually achieved in the group treated with IOLs combined with EWCLs. Grating acuity was significantly poorer than normal in aphakic eyes treated only with EWCLs. Comparison of the two treatment groups revealed that pseudophakic eyes treated with multifocal IOLs had significantly better gating acuity than aphakic eyes. Assessments of optotype acuity and sweep VEP acuity revealed amblyopic deficits in both pseudophakic and aphakic eyes. CONCLUSIONS: Given an absence of serious postoperative complications, neonatal correction of aphakia with IOLs combined with EWCLs can lead to normal grating acuity in a primate model. Correction with EWCLs alone was not sufficient to produce normal grating acuity. Multifocal IOL treatments combined with EWCL provided a significantly better outcome than EWCL methods alone. However, neither IOL nor EWCL methods were able to prevent amblyopia as evaluated using behavioral testing with optotypes or with sweep VEPs.  (+info)

Primary rhegmatogenous retinal detachment: 20 years of change. (2/91)

AIM: To compare characteristics, management, and outcome of two groups of patients with primary rhegmatogenous retinal detachment (RRD) presenting to the same vitreoretinal unit approximately 20 years apart. METHODS: 124 patients in 1979-80 and 126 cases in 1999 were compared. RESULTS: More cases were pseudophakic and fewer aphakic in 1999 than 1979-80. More cases of giant retinal tear and fewer dialyses were operated on in 1999. Vitrectomy was a primary procedure in 63% of cases in 1999 but only 1% in 1979-80. Anatomical success rates were statistically similar: 79.8% primary and 88.8% final success in 1979-80, and 84% primary and 93.6% final success in 1999. CONCLUSION: Surgical management of primary RRD has changed greatly in 20 years. Success rates have changed little, despite availability of differing surgical techniques.  (+info)

Outcomes of extracapsular surgery in eye camps of eastern Nepal. (3/91)

BACKGROUND: Extracapsular cataract (ECCE) surgery is becoming increasingly popular in surgical eye camps of developing countries. This study assesses the outcome of 166 eyes at 6 weeks and 14 and 32 months after ECCE with and without implantation of intraocular lens in refugee camps of eastern Nepal. METHOD: All patients operated on in seven refugee camps during the 3 years before the assessment were included in the study population. Visual acuity, examination of anterior segment and posterior segments, and grading of capsular opacification using a standardised grading system were performed. RESULTS: Of 166 eyes examined, of which 49.4% were aphakic, 58% of eyes had very poor functional vision (WHO severe visual impairment-VA <6/60). After refraction and best correction 19% still had very poor vision. The aphakic eyes had both significantly poorer functional and best corrected vision than the pseudophakic eyes. In patients with intact posterior capsule clinically significant posterior capsular opacification was observed in over 10% of eyes at 14 months and 30% at 32 months. CONCLUSION: It was found that ECCE surgery in eye camps in this setting gave unacceptable outcomes because of a high rate of capsular rupture and posterior capsular opacification. Careful consideration should be given to the quality of the surgical set up and available resources and possibilities of postoperative follow up when ECCE is introduced in eye camps.  (+info)

Visual acuity and quality of life outcomes in cataract surgery patients in Hong Kong. (4/91)

BACKGROUND: Visual acuity, visual functioning, and vision related quality of life outcomes after cataract surgery were assessed in a population based study in a suburban area of Hong Kong. METHODS: A cluster sampling design was used to select apartment buildings within housing estates for enumeration. All enumerated residents 60 years of age or over were invited for an eye examination and visual acuity measurement at a site within each estate. Visual functioning (VF) and vision related quality of life (QOL) questionnaires were administered to interview subjects who had undergone cataract surgery and to unoperated people with presenting visual acuity less than 6/60 in either eye, and a sample of those with normal visual acuity. RESULTS: 36.6% of the 310 cataract operated individuals had presenting visual acuity 6/18 or better in both eyes, and 40.0% when measured by pinhole. 4.5% were blind, with presenting visual acuity less than 6/60 in both eyes. Of operated eyes, 59.6% presented with visual acuity 6/18 or better. 11.2% of the operated eyes were blind with vision less than 6/60. Visual acuity outcomes 6/18 or better were marginally associated with surgery in private versus public hospitals. Lens status (pseudophakic versus aphakic) and surgical period (within the most recent 3 years versus before) were not significantly related to vision outcomes. Mean VF and QOL scores decreased consistently with decreasing vision status. Spearman correlation with vision status was 0.420 for VF scores and 0.313 for QOL scores. Among VF/QOL subscales, correlation was strongest for visual perception (r = 0.447) among VF subscales and weakest for self care (r = 0.171) among QOL subscales. Regression adjusted VF and QOL total scores for cataract operated individuals were slightly lower than for those of visually comparable unoperated individuals (p<0.05). CONCLUSIONS: Cataract operations in Hong Kong did not consistently produce good presenting visual acuity outcomes, suggesting that postoperative monitoring would be useful to minimise visual impairment in this population. Although vision outcomes were consistently correlated with all VF/QOL subscale scores, there was a differential impact with VF subscales usually being affected more by reduced acuity than the more general QOL subscales.  (+info)

Longitudinal study on visual outcome and spectacle use after intracapsular cataract extraction in northern India. (6/91)

PURPOSE: More than 3 million cataract extractions are undertaken in India annually. Almost 60% of these operations are intracapsular Cataract Extractions. The subsequent optical correction is provided by aphakic spectacles. The aim of this study is to assess visual outcome and perceived benefits of post-operative use of aphakic spectacles. METHODS: One hundred and sixty-seven persons who had undergone intracapsular cataract extraction and had been given best corrected aphakic spectacles were evaluated one year following prescription of the best corrected aphakic spectacles. Out of these, 82.6% were re-examined in this interview-based longitudinal study. RESULTS: The mean age of the male participants was 65.95 years and that of females was 71.26 years. 81.2% of the participants were using the provided spectacles. There was no significant association between the spectacle use and gender of the participant. The commonest reason stated by the respondents, for the non-use of the spectacles was 'poor vision'. 61.7% of the current users of provided spectacles had a visual acuity of 6/18 or better. 91.1% of the current users were very satisfied with the spectacles. All the current users could now manage personal activities and the spectacles had facilitated independent mobility. There was no difference in the level of satisfaction between mono-aphakics and bi-aphakics. Among the satisfied users, the modal spherical power was +10 D followed by +11 D. About one-third of these required a cylindrical correction. CONCLUSION: Following intracapsular cataract extraction, provision of the best correction after cataract surgery is desirable to obtain an optimal visual outcome.  (+info)

Comparison of outcomes of primary and secondary implantation of scleral fixated posterior chamber intraocular lens. (7/91)

AIM: To assess and compare the results of primary and secondary implantation of scleral fixated posterior chamber intraocular lens (SFIOL). METHODS: The medical records of a consecutive series of 55 eyes of 55 patients with SFIOLs implanted during (group 1) or after (group 2) complicated senile cataract surgery were retrospectively reviewed and analysed. RESULTS: There were 30 and 25 eyes in group 1 and 2, respectively. Follow up was from 6 to 36 months. Mean logMAR postoperative best corrected visual acuity in group 1 was not significantly different (0.50 (SD 0.36)) from that of group 2 (0.36 (0.21)) (p=0.109). Postoperative best corrected visual acuity of 6/12 or better was achieved in 58.6% and 76.0% in group 1 and 2, respectively. The difference was not statistically significant (p=0.177). In group 1, 25 (83.3%) eyes had a total of 55 early complications, while in group 2, 16 (64%) eyes had 26 early complications (p=0.028). The difference in early complication was statistically significant. For late complication after 1 month, 21 (70.0%) eyes had a total of 37 complications in group 1, while 13 eyes (52.0%) had 19 complications in group 2 (p=0.077). The difference in late complication was not statistically significant. CONCLUSION: Secondary implantation of SFIOL after cataract extraction seems to have a lower early complication rate than primary implantation in complicated cataract extraction although the final visual acuity and late complication rate are not significantly different.  (+info)

Clinical characteristics and surgical outcomes of pseudophakic and aphakic retinal detachments. (8/91)

We retrospectively evaluated the clinical characteristics and surgical outcomes of 20 pseudophakic retinal detachment (RD) patients (20 eyes) and 17 aphakic RD patients (17 eyes). Males were predominated in both groups. The time interval between cataract extraction and RD was 31 months on average in the pseudophakic group, 32 months with intact posterior capsule and 27 months with ruptured posterior capsule, and 148 months in the aphakic group. In 50% of cases with ruptured posterior capsule in the pseudophakic group, RD occurred within 1 year. The anatomic success rate was 95% in the pseudophakic group and 88% in the aphakic group. The most common cause of failure was the development of proliferative vitreoretinopathy. Visual acuities more than 20/40 after RD surgery were found in 13 pseudophakic (65%) and 6 aphakic (36%) eyes. Aphakic patients were more inclined to have silent RD than pseudophakic patients because of their poor visual acuity. Post-operative follow-up is required especially for the first 1 year in cases of damaged posterior capsule due to the high incidence of RD during this period.  (+info)

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 ...
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. ...

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. ...

Cataracts present from birth (congenital cataracts) are sometimes caused by a faulty gene being passed to a child from their parents. This fault means that the lens doesnt develop properly.. Its estimated that theres a family history of congenital cataracts in around one in every five cases of the condition, and recent research suggests genetic causes are responsible for the majority of bilateral congenital cataracts in the UK.. Cataracts can also be associated with conditions caused by chromosome abnormalities, such as Downs syndrome. Chromosomes are the parts of the bodys cells that carry the genes. ...

Cataract surgery in infantile eyes, which are microphthalmic, can be even more demanding.. In addition, the frequent presence of other ocular and systemic anomalies such as nystagmus, glaucoma, amblyopia, and higher rate of postoperative complications may limit the success of cataract surgery.. In our previous study, the investigators examined the intraoperative performance and postoperative outcomes of bilateral cataract surgery in microphthalmic eyes of patients before their first birthday. At 1 year, the postoperative results showed that good visual outcomes could be obtained in microphthalmic eyes.. Since only a few studies have reported outcomes, and that too only short term of cataract surgery on microphthalmic eyes, in this prospective observational study we evaluated the long-term impact of bilateral cataract surgery on eyes with microphthalmos. The investigators examined the outcomes, complication rates, influence of age at surgery on pattern of axial growth and central corneal ...

More rarely, the cataract surgeon may perform "intracapsular cataract surgery," a mature procedure to remove the entire cataract via a bigger cut when the lens continues to be broken or dislocated. You shouldnt feel discomfort throughout the procedure, but might feel pressure and a few discomfort due to the vibrant lights needed for surgery. After wards, you might be instructed to put on a watch patch for many hrs, and might be given eye drops or anti-biotics to prevent inflammation and infection. Generally, you ought to be able to resume your normal activities inside a couple of days, how well you see made considerably clearer due to this safe, quick, and customary procedure.

We live in the Hershey PA area. My son was diagnosed with a unilateral cataract at 2 months old. He had the subsequent surgery and we began the trials with contacts and backup glasses. We tried several contacts and after no luck at 9 months old our doctor began to discuss an IOL implant with us. We were always told that was not an option until he was 2 years old and the best case scenario would be waiting until he was an adult so the prescription would be accurate. We decided to go to Philadelphia to get some other opinions and were comforted by being told that our son would fair well with the use of his glasses, although he would not develop sight with his eyes working together, which the doctors did not think was a big deal. After we had our other opinions our doctor let the IOL go, but still stressed trying the contact lens. We began having issues with communication due to the large practice our doctor was a part of and recently made an appt. with another doctor in the Hershey area. Our son ...

Introduction Globally, cataract is the most frequent cause of blindness, affecting more than 20 million people (1). Most of these people live in rural areas of developing countries, where there are limited ophthalmologically trained personnel or services.. There are two ways to remove the cataractous lens. It can be extracted in its entirety (intracapsular cataract extraction, ICCE) or the lens contents can be removed leaving the posterior lens capsule in place (extracapsular cataract extraction, ECCE). ICCE is a quicker and simpler technique, but is associated with more complications related to disturbance of the vitreous face. It is still commonly performed in rural Africa and Asia, whereas ECCE is the preferred technique in industrialized countries. The disadvantage of ECCE is that, in a proportion of cases, the lens capsule becomes opaque, requiring further intervention in order to maintain good vision.. It is generally agreed that inserting an intraocular lens into the eye during surgery is ...

AIM: To compare visual prognoses and postoperative adverse events of congenital cataract surgery performed at different times and using different surgical approaches. METHODS: In this prospective, randomized controlled trial, we recruited congenital cataract patients aged 3mo or younger before cataract surgery. Sixty-one eligible patients were randomly assigned to two groups according to surgical timing: a 3-month-old group and a 6-month-old group. Each eye underwent one of three randomly assigned surgical procedures, as follows: surgery A, lens aspiration (I/A); surgery B, lens aspiration with posterior continuous curvilinear capsulorhexis (I/A+PCCC); and surgery C, lens aspiration with posterior continuous curvilinear capsulorhexis and anterior vitrectomy (I/A+PCCC+A-Vit ...

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 ...

An IAT score is computed by comparing speed and error rates on the "blocks" (or trials) in which the pairing of concepts is consistent with common stereotypes (images 1 and 3) to the blocks in which the pairing of the concepts is inconsistent with common stereotypes (images 2 and 4). If he is typical of most subjects, Frank will be faster and make fewer errors on stereotype-consistent trials than stereotype-inconsistent trials. While this "gender-career" IAT pairs concepts (e.g., "male" and "career"), other IATs, such as the "race-evaluation" IAT, pair a concept to an evaluation (e.g., "black" and "bad"). Other IATs test implicit attitudes toward body image, age, sexual orientation, and so on. Over 16 million unique participants having taken an IAT as of 2014 (Nosek p.c.). One recent review (Nosek et al. 2007), which tested over 700,000 subjects on the race-evaluation IAT, found that over 70% of white participants more easily associated black faces with negative words (e.g., war, bad) and white ...
In sunny Malibu a real estate agent named Neal Baddin helps the playboy son of one of the worlds most corrupt leaders buy a $30 million mansion. Teodoro Nguema Obiang lives off money taken from the coffers of Equatorial Guinea, a tiny but oil-rich country where most people endure repression and grinding poverty. But Baddin doesnt ask who Obiang is, or where he might have gotten $30 million. He just collects his generous commission. And hes not alone. In Oklahoma a company called IATS facilitates Obiangs purchase of a $38.5 million Gulfstream jet - after a rival company had already turned down his obviously tainted money. Does all of this sound like it should be legal in America? Well, it is. In a meticulously documented report, U.S. congressional investigators recently showed how legal loopholes and lax regulations let foreign kleptocrats treat America like a carefree shopping paradise while their people starve back home. Neither Baddin nor IATS had any legal obligation to know who Obiang ...

Over the course of her admission, we discovered that she had bilateral cataract. The issue was about getting the surgery done while the surgery season was on. And then there was the spectre of diabetic retinopathy which could dampen the surgery.

It was one of our staff who noticed that she was fumbling with things that we realised that her vision was as low as 1/60 ...

In the process of eliminating cataracts, refractive lensectomy nowadays can also correct visual defects such as myopia, hyperopia, astigmatism, and even presbyopia. As well as eliminating the problem of clouded vision, artificial lenses allow patients to discard corrective eyewear. With refractive lensectomy it is possible to correct high refractive defects and to restore vision almost immediately. Cataracts may also be removed in patients affected by high myopia, for whom this problem occurs relatively early in life (between 50 and 60). Multifocal intra-ocular lenses (IOL) may be used to correct a range of visual defects (for example myopia and presbyopia) in a single operation, thereby ensuring optimal 360° vision both close up and at a distance.. Correcting acute visual ...

Pseudoexfoliation is an ocular condition in which a fibrillar, proteinaceous substance is produced in abnormally high concentrations. The shedding of the material can make structures within the eye less resilient. Studies suggest pseudoexfoliation to be 0.6 percent in 52- to 64-year-olds rising to 5 percent in 75- to 85-year-olds. Pseudoexfoliation is routinely identified during a. ...

As of now, we dont know what Zelda can see...since she was born, the question has remained unanswered. She has had at least 8 eye surgeries (Ive lost count) - all in California. She has had a lensectomy, a few vitrectomys and several retinal reattachments. Sometimes the drs say she may have light perception in her "good" eye, the right one which is smaller. They say there is most likely no sight in her left. She rarely opens her eyes but she does understand what to do when I ask her to do so. When she does open them, they are a piercing blue and each goes in a different direction off to the sides. I guess I figure that if she was seeing anything she would want to keep her eyes open all of the time. Luckily, Zelda has excellent "mapping" and traveling skills. She obviously knows our little bungalow inside and out but then theres the neighborhood: "I want to go outside", she says. And from there, shell take her long white cane, head onto the porch, down the concrete steps (no helping please!) ...

To make a panoramic image from photographs, it is essential to be able to calculate the direction in space corresponding to any given position in a given photo. Specifically, we need to know the angles between the view directions of the photos (the alignment of the images), and a radial projection function that relates the distance of a point from image center to the true angle of view, measured from the optical axis of the lens. Given a set of control points linking the images, PanoTools estimates both the alignment and the lens projection by a nonlinear least squares fitting procedure -- optimization. Using the fitted lens parameters, the stitcher can correct each image to match the ideal geometry of the scene, according to whatever projection is chosen for the panorama. Done right, that makes all the images fit together perfectly; moreover, it yields a panoramic image that seems to have been made with a perfect lens. ...
