PURPOSE: To evaluate aetiology, demographic profile, clinical features and outcomes in cases of peripheral ulcerative keratitis (PUK).
METHODS: Seventy-six eyes of 65 consecutive patients with PUK were evaluated in this prospective interventional study over an 18 month period, which were followed for 3 years. The main outcome measures were sociodemographic profile, aetiology, clinical features, management strategies and outcome.
RESULTS: Sixty per cent (39/65) of cases were men and mean age was 45.5 ± 17.9 years. Two-thirds (43/65) of the patients were from rural areas with majority (48/65) belonging to low socioeconomic status. Unilateral disease was present in 83% of patients (54/65) with nasal involvement in 60.5% (46/76) cases. The most common aetiology was Mooren's ulcer (31.5% cases (24/76 eyes)) followed by infection and systemic collagen vascular disease. Meibomian gland dysfunction (17/76: 22.3%) was the most common extraocular association and complicated cataract (12/76:15.7%) was the most common intraocular abnormality. In mild and moderate cases, no significant visual improvement was observed (p = 0.085 and p = 0.156) as compared with the pretreatment status. Surgical treatment was successful in maintaining anatomical integrity in 83.3% (30/36) eyes. Recurrence of the disease was seen in one eye in moderate disease and three eyes in severe disease.
CONCLUSIONS: Mooren's ulcer followed by collagen vascular diseases and infection are important causes of PUK in developing countries. Surgical intervention in perforated cases had good anatomical success and visual prognosis.
