[Associated forms of hereditary chorioretinal degeneration]

A retrospective study of 324 cases of chorioretinal heredodegeneration of all kinds shows an associated pathology in 44% of cases. These associated anomalies point out the need of a complete physical examination, a familial inquest keeping in mind genetic counseling. They are a good model for a high resolution cytogenetic study to find microdeletions which can allow to precise the genome's map.
