PURPOSE To determine the effect of main morphological types and grades of age-related cataracts on refractive error. METHODS We measured 276 subjects with optical compensation prior to the development of cataract. We evaluated 224 eyes with nuclear cataract, 125 with cortical cataract, and 103 with posterior subcapsular (PSC) cataract classified with LOCSIII. We measured visual acuity (VA) wi...

A clinical case of congenital aniridia in combination with high degree hyperopia, cataract, ophthalmohypertension, foveal hypoplasia is presented. The article analyzes the results a complex morphofunctional studies conducted before and after cataract surgery, presents practical data on differential diagnosis glaucoma ophthalmohypertension therapeutic approaches, including use diaphragm contact ...

Abstract Background Cataract surgery is traumatic to the corneal epithelium,scarring and opacity commonest cause of blindness. Objective To study epithelial thickness in different conditions using anterior segment optical coherence tomography (AS-OCT). Patients Methods A case-control including 80 eyes divided equally into 4 groups; group 1:controls,group 2:corneal scarring ,group 3:cataract pat...

Introduction: The decline of visual function with increasing age is a significant concern in elderly. Despite previous work on prevalence of specific ophthalmic pathologies, there has not been enough valid data about overall eye disorders in Tehran yet, and it is poorly defined and not underpinned by strong evidence. The purpose of this study was to investigate the common eye disorders in the e...

Ultrasonography is the only practical method for obtaining images of the posterior segment of the eye when the light-conducting media are opaque. In this study, 182 dogs with ocular abnormalities presented to the Department of Veterinary Surgery and Radiology from December 2008-August 2010 were included. All the animals were subjected to detailed ophthalmic examination and B-scan ultrasonograph...

This study aimed to investigate the prevalence and clinical determinants of cataract and cataract surgery in Korean population. The 2008-2012 Korean National Health and Nutrition Examination Survey was analyzed, which included 20,419 participants aged ≥ 40 years. The survey is a multistage, probability-cluster survey, which can produce nationally representative estimates. Prevalence of cataract...

Background: Different surgical treatment options are used to treat cataracts, such as Manual Small Incision Cataract surgery (MSICS) and Phacoemulsification. The present study compares the visual outcomes of phacoemulsification MSICS in senile cataract patients. Methodology: A quasi-experimental was conducted with 270 patients aged between 50 70. Patients diagnosed were included divided equally...

Cataract may cause moderate vision impairment (<6/18 to 6/60), severe vision impairment, (<6/30 to 3/60) or blindness (<3/60). People may have bilateral or unilateral cataract, so it is more useful to consider the number of eyes than the number of people who require surgery. Cataract surgical rate (CSR) is the number of cataract operations performed in one year, per million population. It is a ...
