In a hospital-based case-control study of 1441 patients with age-related cataracts and 549 controls, we studied associations between types of cataract--nuclear, cortical, posterior subcapsular, and mixed--and a number of physiologic, behavioral, environmental, and biochemical variables. Using polychotomous logistic regression analysis, we found an increased(More)
The problem of phacomorphic glaucoma is a rather common entity in rural India owing to the delay in getting the cataract removed and the preponderance of cortical matter, compared with the Western world. The authors in India, South East Asia and Australia, have managed the problem differently leading to controversies. The pathogenesis has been investigated(More)
We analyzed the characteristic features and intraoperative behavior of pre-existing posterior capsule breaks in 12 cases of traumatic cataract caused by perforating ocular trauma. The interval between the occurrence of trauma and cataract surgery ranged from three days to one year. Two distinct types of posterior capsule breaks were found: one had thick,(More)
The prevalence of blindness in India is 14.9 per 1000. Eighty per cent of this blindness is due to cataract alone. Most of the cataract blinds in the country are in the rural areas while the surgical service delivery network is concentrated in the urban areas. Thus a large proportion of patients in the rural areas continue to remain blind. This situation(More)
Cryotherapy of the palpebral conjunctiva with oral aspirin has been evaluated in mixed-type active vernal keratoconjunctivitis. The symptoms and signs were recorded on a four-point scale. In 15 patients, we used cryotherapy of the palpebral conjunctiva in 30 eyes (-60 degrees C to -80 degrees C for 30 seconds, repeating the freeze-thaw cycle 2-3 times). All(More)
In a prospective study, we evaluated the sensitivities of direct microscopy using potassium hydroxide 10% wet-mount preparations and culture for definitive diagnosis of keratomycosis in 171 clinically suspected fungal corneal ulcers. Although cultures were positive in 88 eyes (51.46%), the fungus could be demonstrated by KOH preparation in 94.3% (83 of 88)(More)
PURPOSE To find out the role of Catalin in the prevention of posterior capsular opacification (PCO), we undertook this experimental study in rabbits. METHODS Twenty rabbits (10 for the Catalin group and 10 for the placebo group) were operated on for extracapsular clear lens extraction in an aseptic environment. In all cases, capsulorrhexis of 8 mm(More)
We studied 16 children, ranging in age between 3 and 8 years, who had posterior chamber intraocular lens implantation and developed inflammatory pupillary-block glaucoma. Prophylactic peripheral iridectomy had not been performed in any of the eyes. The patients were treated medically, and YAG laser iridotomy was performed successfully one week after initial(More)
