PURPOSE: To report the spectrum of keratitis treated within 3 months of acute COVID-19 infection.
METHODS: Retrospective, descriptive case series study of 19 eyes of 16 patients who presented at tertiary eye care centre in Southern India.
RESULTS: Median age of the patients was 43(IQR 35-55.5) years. Majority (15/16, 93.75%) were males. Unilateral affliction was predominant (13/16, 81.25% patients). Nine had a history of hospitalization, five had received oxygen supplementation and five had been treated with steroids during COVID-19 illness. The median duration between COVID-19 diagnosis and the ocular symptoms in the eye was 29 (IQR 22-57) days. Microbiological diagnosis consisted of microsporidia in nine eyes of seven patients, fungus in six patients, Pythium in one patient, and herpes zoster ophthalmicus in one patient. One patient had neurotrophic keratitis. Therapeutic penetrating keratoplasty was performed in five patients, glue application in two patients and three were managed with tarsorrhaphy with/without amniotic membrane grafting or tenonplasty. There was medical and surgical cure in all patients.
CONCLUSIONS: Microsporidia was the commonest cause of keratitis, followed by fungal infection. Majority of the microsporidia infections were keratoconjunctivitis. The fungal isolates identified were Aspergillus and Mucor species. All patients responded to conventional management guidelines with favourable outcomes.
