Clinical profile of corneal ulcers at a tertiary care hospital, North-West Rajasthan, India

Abstract

Background Corneal ulcer is an inflammatory or more seriously infective condition of the cornea involving disruption of its epithelial layer with involvement of the corneal stroma. Aim The aim of this study was to evaluate the clinical profile of corneal ulcers at Sardar Patel Medical College and associated group of hospitals, Bikaner, Rajasthan, India. Patients and methods This is a prospective, longitudinal, observational study that was conducted for two years from October 2020 to October 2022. It involved 100 clinically diagnosed corneal ulcer patients, recruited by consecutive sampling, attending the Outpatient Clinic at the Department of Ophthalmology, who were willing to participate in the study. Clinical evaluation included the sociodemographic aspects and the ulcer characteristics, including its location, shape, depth, presence of satellites, and hypopyon. Corneal scraping was performed in 60 cases with full aseptic measures after the instillation of topical anesthetic and the samples were sent to the Microbiology Department for further processing. Results The maximum proportion (52%) of the study population were 41-60 years old, with 58% of the patients being males, and 75% from rural areas. Most of the ulcers (68%) were central or paracentral in location, with 38% being of ameboid shape and 48% being superficial. Based on etiology, 48% were fungal, 32% were bacterial, 16% viral, 1% parasitic, and 3% noninfective. The most common pathogen was Aspergillus fumigatus followed by Staphylococci and viral infection. Conclusion Corneal ulcers were found most commonly in males aged 40–60 years hailing from rural areas engaged in agriculture. The most common etiological agent was Aspergillus fumigatus followed by Staphylococci.
