Book Description
Excerpt from Hereditary Diseases of the Eye Resulting in Blindness: Their Social Consequences, the Measures That May Be Proposed The eye especially lends itself to researches in heredity, because it is possible to observe the hereditary anomalies directly, and very often to measure their dimensions. It is for this reason that there exists to-day a vast and detailed literature on hereditary diseases in ophthalmology. These researches concern themselves above all with pedigrees, for it is primarily the familial appearance of these affections which has interested the various observers. It is thus that we have learnt the mode of transmission in the greater number of eye diseases due to a modification of the idioplasm. The isolated cases of these eye diseases, however, have been neglected almost to the present day. The result is that our knowledge of the number of single-case pedigrees is almost nil despite the innumerable statistical studies, and that we also know very little about the descendants of these patients.
