Abstract

Background - Corneal diseases constitute a major cause of visual loss and blindness in the world today, majority of which is avoidable. Aim – The purpose of this study was to estimate the cause and severity of visual impairment among subjects with medically refractive corneal diseases. Design – Retrospective chart review. Material and methods – The details of cases (n=38) with medically refractive corneal diseases awaiting surgical management in the cornea clinic of a tertiary care hospital during a period of one year were recorded. Results - 65.78% were >40 years of age. 26.31% had bilateral disease. Central cornea was involved among 70.83%. Most common cause of corneal blindness was corneal opacity (27.08%). Trauma constituted 30.76% corneal opacities. 77.08% cases had visual impairment. 52.08% were blind. Those with BCVA >6/18 suffered from intractable glare and photophobia. Conclusion – Identification of avoidable and treatable causes of corneal blindness can help to plan strategies in the prevention, cure and rehabilitation of subjects with corneal diseases.
