Abstract

A hospital-based study in the northwest of Cambodia identified 453 blind adults and 30 blind children seen consecutively at the provincial ophthalmic department between January and September 1994. Blindness was defined as a visual acuity of less than 3/60 in the better eye. Cataract was the cause of blindness in 266 (59%) adults, of which 15 cases (3.3%) were surgical complications. Sixty-three cases (14%) were due to glaucoma and 53 (11.5%) patients had corneal scars, of which 12 (2.5%) were due to trachoma. Bilateral trauma, usually due to landmine injuries, accounted for 17 patients (4%). Of the 30 blind children, corneal scarring accounted for 12 cases (40%), congenital causes for 14 (47%) and optic atrophy secondary to meningitis for 4 (13%). There is at present an inadequate ophthalmological service for the vast majority of people living outside the capital Phnom Penh. These hospital-based data suggest that there is a need to train general doctors to surgically manage patients with visual loss from cataract and glaucoma, which together account for 70% of all cases of blindness, and highlight the need for a large population-based survey.
