Background: Pigmentary retinosis is a disease of genetic origin to which is associated multiple social problems related with its origin. Objective: to describe certain important social-genetic aspects of the Pigmentary retinosis for their management and prevention. Method: a cross-sectional descriptive study at the Pigmentary Retinosis Center of Camagüey was performed, from October 1991 to July 2008, with 209 patients affected by this disease. Data were extracted of the genetics´ clinical histories, which were poured in a summary model and then statistically processed by means of descriptive techniques. Results: of the 209 families, one-hundred thirteen index cases were of the female sex and ninety-six of the masculine one. Consanguinity in fifty-three families with defined inheritance was found. The most frequent family relationship was that of first cousins. There was a b statistical association among consanguinity and recessive autosomal inheritance that was in turn the most frequent way of inheritance. There was a bigger number of studied and investigated women than men. Syndromic forms of the disease were presented in sixteen families (7,65%). The Usher’s syndrome turned out to be the most frequent one. Conclusions: the hereditary nature, the presence of consanguinity and the syndromic forms of the disease are important social-genetic aspects related with pigmentary retinosis, for what its study should be deepened with a view to the prevention and management of the disease.
