Clinical characteristics, predisposing factors, and treatment outcome of

purposeTo report clinical characteristics, predisposing factors, and treatment outcome of Curvularia keratitis.

methodsRetrospective chart review of consecutive culture-proven Curvularia keratitis patients who presented to a tertiary eye care center in north India. Patients with mixed infections with Curvularia as one of the pathogens were also included. Standard case report form was developed to capture demographic information, clinical features, etiology, treatment, and outcome. Binary logistic regression was done to ascertain the effect of identified variables on final visual acuity.

resultsMedical records of 97 patients of Curvularia keratitis were reviewed. Median age of patients was 45.3 years. Seventy-nine (79.4%) patients presented during the months of September to November. History of corneal trauma was present in 69.1%. Trauma from sugarcane leaf was identified in 66.1% of cases with corneal trauma with vegetative matter. Presenting visual acuity was worse than 20/60 in 57.8% of patients. Hypopyon and pigmented plaque-like infiltrate was present in 16.5% and 28.8% of patients, respectively. Mixed infection was reported in 14.4% of cases. Median time of antifungal therapy was 24.5 days. Surgical intervention was required in 18.5% cases. Of all, 11.1% patients achieved final VA of more than 20/200 who were managed surgically as compared to 68 (86%) patients who were managed medically. Younger age, absence of comorbidities, and lesser infiltrate size were found associated with good final visual acuity.

conclusionWorking males were most affected by Curvularia keratitis. Corneal trauma with sugarcane leave was the most common predisposing factor in the study area. Most of the cases presented with worse visual acuity but could be managed medically.
