PURPOSE To identify the microbial aetiology of infectious endophthalmitis and to determine the in vitro antibacterial susceptibilities of bacterial isolates. METHODS A retrospective analysis was carried out of all patients presenting between January 1997 and December 2006 with clinically diagnosed infectious endophthalmitis who underwent microbiological(More)
PURPOSE To study the epidemiological characteristics and laboratory diagnosis of fungal keratitis seen at a tertiary eye care referral centre in South India. METHODS A retrospective review of all culture-proven fungal keratitis seen over a 3-year period, September 1999 through August 2002. RESULTS Fungal aetiology were confirmed in 1095 (34.4%) of 3183(More)
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(More)
AIMS To identify the etiology, incidence and prevalence of ocular bacterial infections, and to assess the in vitro susceptibility of these ocular bacterial isolates to commonly used antibiotics. MATERIALS AND METHODS Retrospective analysis of consecutive samples submitted for microbiological evaluation from patients who were clinically diagnosed with(More)
AIMS To determine the sensitivity, specificity and predictive values of potassium hydroxide (KOH) wet mount, Gram stain, Giemsa stain and Kinyoun's acid-fast stain in the diagnosis of infective keratitis. METHODS A retrospective analysis of all patients with clinically diagnosed infective keratitis presenting between September 1999 and September 2002 was(More)
PURPOSE To study the epidemiological characteristics of bacterial keratitis seen at a tertiary eye care referral centre in south India. METHODS A retrospective review of medical records of all culture-positive bacterial keratitis which were seen over a 3 years period, from September 1999 through August 2002 was performed. After clinical evaluation corneal(More)
PURPOSE To determine the epidemiological and clinical characteristics of Acanthamoeba keratitis and also to determine the sensitivity and specificity of smears in the detection of Acanthamoeba. MATERIALS AND METHODS A retrospective review of all culture-positive cases of Acanthamoeba keratitis seen between October 1999 and August 2002 was performed.(More)
BACKGROUND & OBJECTIVE Infective keratitis is rare in the absence of predisposing factors. The pattern of risk factors predisposing to infective keratitis varies with geographical regions and also influences the type of infection that occurs. The present study was aimed to identify the specific risk factors that predispose the infective keratitis (non(More)
PURPOSE To analyse the in-vitro efficacy of commonly used antibacterials against bacterial pathogens from corneal ulcers. METHODS We evaluated 596 patients seen over 18 months, period, September 1999 through March 2001. Corneal scrapings were subjected to microscopy and cultures using standard protocols. Antibacterial susceptibility of isolated bacteria(More)
This paper proposes an algorithm for the recognition of handwritten characters in Malayalam, a South Indian language. It introduces the salient features of Malayalam script and lists the approaches used for character recognition. Malayalam scripts are rich in patterns because of their complex curved form, larger number of basic elements and the presence of(More)
