Objective: To determine the risk factors, causative organisms, sensitivity patterns and treatment outcomes of infective corneal ulcers. Methods: The is a prospective cohort study carried out from January 2018 to December 2019 at the Department of Ophthalmology, Fauji Foundation Hospital (FFH) Rawalpindi. A total of 65 eyes of 65 patients of corneal ulcer meeting the inclusion criteria were evaluated and corneal scrapes were sent for microbiological assessment.  Variables studied were age, gender, risk factors, onset and duration of symptoms, best corrected visual acuity (BCVA), treatment and complications. Results: Out of 65 eyes of 65 patients, 40 (61.5%) were females and 25 (38.4%) were males. Most common local risk factor was ocular surgery (29.2%) followed by ocular trauma (23.1%). Diabetes was present in 44.6% of the cases. Culture results after corneal scrapings were positive for 39 (60%) of the total samples, while 26 (40%) had no growth. Bacterial growth was present in 51.3% of eyes, fungal in 28.2% while 20.5% of the eyes were infected with polymicrobial organisms. Most common pathogens were Pseudomonas (25.6%) that were most sensitive to ciprofloxacin. By the end of the follow-up period 40 cases (61.5%) showed improvement. Conclusion: This study concluded that isolated Pseudomonas was the most common pathogen. Prompt diagnosis with culture sensitivity tests are very much needed in developing countries to avoid blindness due to keratitis. Keywords: Infective keratitis, risk factors, corneal ulcer, culture sensitivity.

BACKGROUND Corneal ulcer is the leading cause of ocular morbidity and monocular blindness worldwide. To effectively prevent blindness in patients with corneal ulcer, a proper understanding of the risk factors predisposing to ulceration, its clinical and microbiological characteristics are essential. Timely identification of aetiological agents causing corneal ulcers and their prompt treatment helps to save the vision. We wanted to detect aetiological agents of corneal ulcer with special references to fungal causes and characterize the fungal aetiological agents to species level. METHODS This is a cross sectional study, conducted in Government Medical college, Kozhikode, between January 2016 and June 2017. All patients who were clinically diagnosed as cases of infectious corneal ulcer in the Ophthalmology department, Government Medical College, Kozhikode were included in the study. Corneal scrapings collected from the infected eye were subjected to microbiological examination and culture. A total of 120 cases were analysed. Each patient was examined with the slit lamp bio microscope after staining with fluorescein. Scrapings from cornea at the site of corneal ulcer were collected by ophthalmologist after a detailed clinical history and examination of the affected eye. The laboratory procedures used in the diagnosis of infectious keratitis were based on direct visualization of organisms by subjecting corneal scrapings to Gram stain and KOH wet mount and inoculation of material on to blood agar and Sabouraud dextrose agar. RESULTS Among the 120 cases, a total of 49 cases were culture positive. Twenty-one [17.5 %] were bacterial, twenty-two [18.34 %] were fungal and six [5.0 %] were poly microbial [bacteria and fungus]. Among the fungal aetiology, fusarium species was most common [32.14 %], followed by aspergillus species - 25.0 %. Trauma was the major risk factor. Diabetes mellitus, exposure keratitis were the other comorbidities / risk factors. CONCLUSIONS This study shows majority of infected corneal ulcers are associated with risk factors and the aetiology are mainly fungi. Microscopy, culture, and clinical correlation helped in adequate management. Thus, prognosis and outcome of corneal ulcers rely on timely identification of their aetiology and prompt treatment.

A Prospective Study

Corneal infections are one of the leading causes of ocular morbidity and blindness world-wide. If normal defence mechanisms of the eye are compromised, almost any microorganism can invade the cornea. It is important to know the exact aetiology of corneal ulcer to institute appropriate therapy in time, least serious consequences may follow.  To isolate and identify the fungi from corneal scrapings of suspected keratitis patients. A prospective study of Fungal keratitis was conducted at Al-Azhar Medical College & Super Speciality Hospital in Thodupuzha, Kerala a tertiary care hospital with a capacity of 650 beds. The duration of the study was two years from January 2018 to January 2020. Patients with suspected fungal corneal ulcers presenting in the Out-Patient Department (OPD) of Ophthalmology were investigated for fungal etiology in the Department of Microbiology were included in this study. Each patient was examined with slit lamp. Data collected from history given by patient and patient examination. Using standard techniques. The specimens collected were then smeared on two slides, which were stained with Gram stain (for bacterial keratitis) and 10% potassium hydroxide preparation (for fungal keratitis) studied under light microscope. Of the 866 patients with corneal ulcer investigated, 83 cases with fungal and 36 with bacterial aetiology was identified. Males were more commonly affected and were mostly in the age group of 31-40 year. It was seen that trauma was the most common predisposing factor especially in the agriculturists and the farmers. Among the identified fungi, most were hyaline. Of the 83 positive specimens, the most frequent agent isolated was Fusarium species in 31 (37.3%) cases. 23 (27.7%) was the second most common followed by , ., . Candida albicans were 5 (6%) followed by 1 (1.2%). Fungal Keratitis is a serious problem usually following corneal trauma, it requires rapid detection and identification of fugal agents for treatment to prevent disastrous consequences.

Introduction: Corneal ulcers are the second most-common cause of preventable blindness after cataract in tropical developing countries. Fungal corneal ulcers constitute 30 to 62 % of the total microbial culture-positive corneal ulcers. Objective: To study the epidemiological characteristics, risk factors and laboratory diagnosis of fungal corneal ulcer in the Sundarban Region, West Bengal, eastern India. Materials and methods: A retrospective review of 399 culture-positive, fungal corneal ulcers out of a total 928 corneal ulcer patients attending a tertiary care hospital in Kolkata, eastern India, over a period of four years from February 2007 to January 2011. Results: Males (246; 61.65 %) were more commonly affected than females (P < .0001). The affected people were mostly (342; 85.71 %) residing in the rural areas (P < .0001). 196 patients (49.12 %) were involved in agricultural activities (P < .0001). The younger people of, 21 - 50 years of age, were particularly prone to this disease (269; 67.41 %). Corneal trauma (354; 88.72 %) was the commonest risk factor (P < .0001) and 261 patients (61.41 %) had a history of trauma with vegetative matter (P< .0001). The use of topical corticosteroids was implicated in 65 (16.29 %) cases. The incidence of the disease was highest in the monsoon season, between June to September (192; 48.12 %). The aspergillus spp was the most common fungal growth (151; 37.84 %), followed by an Fusarium spp (81; 20.3 %). Conclusion: The fungal corneal ulcers are an important cause of ocular morbidity in people residing in the Sundarban Region. The identification of the etiology and the predisposing factors of corneal ulcers in this region are important for the prevention and early treatment of the disease.

Microbial Profile

Background-Visual impairment due to corneal ulceration has for long been acknowledged as leading cause of blindness both worldwide and in India only next to Cataract. The aetiology for infective corneal ulcer varies considerably with occupation of patients in different regions of India. Thus, continuing with empirical management without lab diagnosis leads to protracted clinical course. So, understanding the microbial profile of corneal ulcers in agriculture dependent population of Southern Assam helps in improved management of this morbidity. Aims- To 1) Find the prevalence of infected corneal ulcers in untreated patients attending Ophthalmology department of a tertiary care hospital of Southern Assam. 2) Study the pattern of microbial aetiology in the infected corneal ulcer cases. 3) Find the association of infected corneal ulcers with various attributing factors. Method-Corneal scrapings from 86 routine untreated cases of corneal ulceration from Ophthalmology Department were studied prospectively from Dec2017 to Jan2019 and subjected to Gram staining and direct examination with 10%KOH. Culture on SDA and Blood Agar were incubated at 25°C and 37°C respectively and followed up for 3 weeks before declaring sterile. Antimicrobial sensitivity was performed for bacterial isolate and yeast-like species. Slide culture and LPCB tease mount were done for identification of moulds. Result- Out of the 86 cases, 58 were positive in direct microscopy, of which 44 were culture positive. Of the 28 samples negative in direct microscopy, 2 were positive by Culture. Bacterial isolates were found in 5 cases and fungal aetiology in 41 cases. Conclusion- The prevalence of infected corneal ulcer as per standard of Culture positivity is 53.5% (46/86). Mycotic involvement was found in 90% cases. Important fungal isolates identified were Aspergillus species, Penicillium species, Curvularia species, Fusarium species, Sarocladium species. Higher prevalence was significantly associated with harvesting season, agricultural practice and history of trauma while diabetes and steroid intake were not significantly associated with mycotic ulcers. Keywords: Corneal ulcer, Assam, Fungal, Fusarium, Sarocladium, Pseudomonas.
