Pupillary diameters in the affected and unaffected eyes of 327 patients with uniocular red eye were assessed during fixation of a distant target. The mean pupillary diameters were similar in the unaffected eyes in each of eight diagnostic groups, but were significantly different (F = 3.84, p less than 0.001) in the diseased eyes. With corneal abrasions (p less than 0.001), marginal keratitis (p...

During a one-year survey 283 corneal ulcers from 274 patients were seen at St John's Eye Unit of Baragwanath Hospital. Central bacterial ulcers constituted the largest problem, and the commonest isolate in this group was Streptococcus pneumoniae. Mycotic and dendritic keratitis were relatively uncommon, while marginal catarrhal ulceration secondary to chronic staphylococcal lid disease was freq...

purpose : to report an atypical case of acanthamoeba keratitis. patients & methods : a 19-year-old girl presented with a history of recurrent herpetic keratitis and a history of short-time contact lens wear. laboratory work-up for herpetic, bacterial, and acanthamoeba sources were negative and the patient failied to follow up. on later presentation she had corneal necrotizing stromal ulcer need...

PURPOSE To determine risk factors and clinical signs that may differentiate between bacterial, fungal, and acanthamoeba keratitis among patients presenting with presumed infectious keratitis. DESIGN Hospital-based cross-sectional study. METHODS We examined the medical records of 115 patients with laboratory-proven bacterial keratitis, 115 patients with laboratory-proven fungal keratitis, an...

PURPOSE The goals of the study were the following: 1) to show the epidemiology of microbial keratitis (MK) in the southeast Brazil, 2) to compare the epidemiological differences between fungal (FK) and bacterial keratitis (BK), and 3) to evaluate the frequency which ophthalmologists accurately differentiate bacterial keratitis from fungal keratitis based on clinical diagnosis. METHODS A retro...

Introduction Contact lens wearing has been increased globally during recent decades, which is one of the main risk factors for developing microbial keratitis. Microbial keratitis a severe and dangerous condition that causes cornea inflammation. It can lead to corneal scarring perforation or even endophthalmitis visual loss if it remains untreated. Among bacterial, fungal, protozoal, viral agent...

PURPOSE The purpose of this study is to describe the diagnosis, course, and outcome of a case of Acanthamoeba and Stenotrophomonas keratitis with a fungal keratitis in the contralateral eye. METHODS A case of Acanthamoeba and Stenotrophomonas keratitis was diagnosed with confocal microscopy and cultures with confocal diagnosis of fungal keratitis in the fellow eye. RESULTS During the initia...

PURPOSE To determine the influence of risk factors, climate, and geographical variation on the microbial keratitis in South India. METHODS A retrospective analysis of all clinically diagnosed infective keratitis presenting between September 1999 and August 2002 was performed. A standardised form was filled out for each patient, documenting sociodemographic features and information pertaining ...
