The study aimed at identifying the causes of childhood blindness at ECWA Eye Hospital, Kano. The causes of visual loss in 31consecutive patients aged <16 years who attended the ECWA eye Hospital
between 1993 and 1996, who had vision of <3/60 in the better eye were recorded. The eyes were examined with a slit lamp or flashlight a loupe, and an ophthalmoscope. The intraocular pressure was
taken with either a Schiotz or an applanation tonometer. There were 14 males (45.0%), the mean age was 6 years; range: 1 to 15 years. Corneal causes were responsible for blindness in 54.8%. Measles was responsible for 10 cases; neonatal infection was responsible in 2 cases. Four cases were due to lens lesions. By aetiologic category, childhood factors accounted for (32.3%). The causes in 51.7% were not known. Hereditary factors and perinatal factor accounted for 6.4% cases each. Intrauterine factors were responsible for 1 case. Eighteen (58.6%) of the cases were due to avoidable causes; 12 (38.4%) being preventable and 6 (19.2%) treatable. The causes of Childhood blindness in this study are consistent with those of low economic region with high prevalence of avoidable blindness.
Keywords: Childhood, blindness, causes, treatable, avoidable, preventable.
