Heredity of Aniridia


A VERY remarkable pedigree of aniridia was published in 1915 by an American ophthalmologist, Samuel Risley. It was undoubtedly issued in good faith by a man, now dead, who accepted, without verification, the statement of a hospital patient who suffered from the defect. This almost blind man, aged 27, described the occurrence of a total absence of iris in 111 of his 119 relations in four generations; he gave, moreover, the age, or age at death, and the Christian name of most of these 119 relations; his statement was confirmed, from hospital notes, in the case of one individual only.
