INTRODUCTION Corneal damage associated with abuse of topical anesthetics is a rare clinic entity. Topical anesthetic abuse is one of the causes of ring keratitis. Ring keratitis is easily overlooked because it can mimic acanthamoeba keratitis or other infectious keratitis. The outcome is often poor, leading to persistent epithelial defects, corneal scarring, and perforations. CASE PRESENTATIO...

Bacterial keratitis is a serious ocular infectious disease that can threaten vision. The disease generally progresses rapidly and can lead to corneal scar, stromal abscess formation, perforation, and dissemination to adjacent tissues if not treated properly. Recent studies showed that corneal collagen crosslinking (CCC) using ultraviolet-A/riboflavin is effective in the treatment of bacterial k...

Penetrating keratoplasty carries an infectious risk. Its requirement for topical corticosteroid therapy facilitates fungal growth with resulting keratitis. Although progression of fungal keratitis to intraocular infection is uncommon, endophthalmitis resulting from keratitis usually has a poor visual prognosis. Fungal infection under these circumstances remains a diagnostic and therapeutic chal...

PURPOSE To report the clinical course, microbiologic findings, treatment, and outcomes of overnight orthokeratology associated microbial keratitis. METHODS Four cases of overnight orthokeratology associated microbial keratitis are reported. RESULTS Four patients aged 14-23 years (mean 18 years) who had central or paracentral corneal ulcers were included. Visual acuity at presentation ranged...

BACKGROUND Corneal ulcers are one of the most common eye problems in the horse and can cause varying degrees of visual impairment. Secondary infection and protease activity causing melting of the corneal stroma are always concerns in patients with corneal ulcers. Corneal collagen cross-linking (CXL), induced by illumination of the corneal stroma with ultraviolet light (UVA) after instillation o...

purpose: to evaluate changes in indications of corneal transplantation at labbafinejad medical center during 2001-2003. methods: records of 563 from 684 patients who had undergone corneal transplantation from oct. 2001 to oct. 2003 were evaluated. all the procedures were performed by corneal surgeons and fellows. findings: there were 292 male (51.9%) and 217 female (48.1%) subjects ranging in a...

PURPOSE To describe the demographic characteristics, associated factors and causative agents of infectious keratitis in the elderly in a tertiary referral center in São Paulo, Brazil. METHODS A retrospective review of all patients aged 60 years and over with a presumptive diagnosis of infectious keratitis who had material collected for microbiological analysis, between the years 1975 and 2007...

PURPOSE To compare the sensitivity and specificity of confocal scan with the results of corneal and/or contact lens case smear and culture in the diagnosis of infectious keratitis. METHODS This was a diagnostic test study. Confocal scan and corneal and/or contact lens case smear and culture were performed in all patients with a clinical diagnosis of infectious keratitis at Labbafinejad Medica...

Purpose: To analyze epidemiological and microbiological aspects of microbial keratitis in children and adolescents. Methods: This retrospective cohort study was conducted at the Department of Ophthalmology and Visual Science, Escola Paulista de Medicina, Universidade Federal de São Paulo, between July 15, 1975, and December 31, 2010. We analyzed corneal samples from 859 patients with clinical...
