Childhood blindness in Lebanon

A survey in the Lebanese schools for the blind revealed that 77% of childhood blindness in the country was genetically determined. Two thirds of the hereditary blindness cases were due to autosomal recessive conditions; the high frequency of consanguineous marriages in Lebanon was the underlying cause of this finding. There is marked similarity in the etiology of childhood blindness in Cyprus and Lebanon, for both countries are somewhere between the highly developed countries.
