Abstract
PURPOSE: To evaluate the causes and management outcomes of acquired corneal opacity in a preschool age group (0-5 years) at a tertiary care hospital. METHODS: Medical records of all cases (0-5 years) with acquired corneal opacity presenting to the cornea clinic of a tertiary eye care hospital from February 2013 to January 2014 were evaluated for age of onset, age at presentation, sex, laterality, cause of opacity, visual acuity, nutritional status, and socioeconomic class of the parents. The etiology of corneal opacity and the type of intervention with outcome at 3 months follow-up were recorded. RESULTS: A total of 106 cases were included in the study. The most common cause of corneal scarring was healed infective keratitis (35.8%). Chemical injury, mechanical trauma, and keratomalacia were the other causes, affecting 21.8%, 20.8%, and 16% of the cases, respectively. Optical iridectomy was the most commonly performed procedure (35.8%), followed by lens aspiration with intraocular lens implantation (17.9%) and penetrating keratoplasty (17%). The mean corrected visual acuity (spectacle or contact lens) at the time of presentation and at 3 months after treatment was 2.9 ± 0.3 (perception of light) and 2.2 ± 0.9 (hand motions) logarithm of minimum angle of resolution (logMAR) units, respectively. CONCLUSIONS: Chemical injury and keratomalacia are the major causes of acquired corneal opacity in preschool age groups in India and are associated with poor visual prognosis.
