Ocular dimensions in the heredity of angle-closure glaucoma.

It has long been recognized that heredity plays a part in the aetiology of glaucoma. Fran ois and Heintz-de Bree (I966) postulated a dominant heredity in open-angle glaucoma. They noted a 98 per cent. penetrance for a dominant gene in some families, but admitted that in other families the penetrance for a dominant gene was very low.
