BACKGROUND A review of pediatric cataract cases operated between January 2003 and March 2005 in the tribal belt of central India was carried out. AIM We present the profile of cataract cases in children <or=18 years and postoperative visual status in the eyes operated upon. SETTINGS AND DESIGN This was a retrospective medical record retrieval type of cohort study in a hospital setting. MA...

Age-related cataract is the leading cause of visual loss worldwide, with developing nations carrying most of this burden. The prevalence of cataract doubles with each decade of age after 40 years, such that most people in their 80s and 90s will be affected. Although cataract removal and intraocular lens implantation effectively treats this condition and restores good vision, cataract surgery is...

purpose: to identify the profile of cataract surgery in an iranian population. methods: this population-based survey was conducted on adults aged ≥50 years and over in 2009 at varamin district. cataract surgical coverage (csc) was defined as the proportion of operable cataractous eyes (best-corrected visual acuity [bcva] < 6/18 due to cataracts) that had been operated. poor outcome was defined ...

Although worldwide data is incomplete, cataract is probably the leading cause of blindness in the world [l]. A recent review of global data on blindness suggests that of the estimated 42 million blind in the world, approx. 17 million are blind from cataract [2]. It is particularly tragic that cataract should cause such a large share of blindness because the surgical techniques for removing lent...

PURPOSE To describe the prevalence of cataract in older people in 2 areas of north and south India. DESIGN Population-based, cross-sectional study. PARTICIPANTS Randomly sampled villages were enumerated to identify people aged ≥ 60 years. Of 7518 enumerated people, 78% participated in a hospital-based ophthalmic examination. METHODS The examination included visual acuity measurement, dila...

PURPOSE To evaluate safety and efficacy of day care cataract surgery in developing country. PATIENTS AND METHODS This prospective study included 200 patients planned for cataract surgery during October and November 2012 divided in to two groups, day care cataract surgery (DCCS) and inpatient cataract surgery (ICS), with same number of male and female patients right and left eyes. All patients...

Many factors such as aging, changes in blood electrolytes levels, and possibly family history are involved in senile cataract formation. Changes in serum electrolytes levels can induce changes in aqueous electrolytes levels and effect on lens metabolism and probably cataract formation. In this paper, we study serum level of Na(+ )and K(+) in senile cataract patients and normal individuals. Meth...

Reading rates are slower for persons with low vision than for normally-sighted persons. This study investigated the change in reading performance and reading eye movements when we simulated the two most common causes of low vision--central field loss and cataract--and their combination (scotoma + cataract). Three subjects read sentences with each of these simulated impairments at five different...

AIMS Women suffer disproportionately more from cataract blindness compared to males in low- and middle-income countries. Two large population-based surveys have been undertaken in India at an interval of 7 years and data from these surveys provided an opportunity to assess the trends in gender differentials in cataract blindness. MATERIALS AND METHODS Data were extracted from the surveys to d...

Age-related cataract is a major cause of blindness worldwide, and cortical cataract is the second most prevalent type of age-related cataract. Although a significant fraction of age-related cataract is heritable, the genetic basis remains to be elucidated. We report that homozygous deletion of Epha2 in two independent strains of mice developed progressive cortical cataract. Retroillumination re...
