Between 1976-1980, medial and social service sources were used to ascertain cases of retinitis pigmentosa in Maine [USA] (1980 population, 1,124,660). As of July 1, 1980, 241 clinically prevalent cases of retinitis pigmentosa were ascertained. Extensive pedigrees were collected for 185 of the subjects and medical records were obtained. Cases (114) were further evaluated by clinical examination, including electroretinography. Adjusting for incorrect diagnosis (8 of 114, 7%) and underascertainment (23 of 185, 12.5%) prevalence of retinitis pigmentosa in Maine was 236 cases, 21/100,000 population or 1:4,756. Excluding Usher and Bardet-Biedl syndromes, the prevalence is 1:5,193. Estimated birth incidence of persons who will become affected with nonsyndrome retinitis pigmentosa is 1:3,544. Incidence of newly diagnosed cases per year is about 6/1,000,000 population. Among kindreds, 16 of 85 (19%) were autosomal dominant, 55 of 85 (65%) autosomal recessive or isolated cases, 7 of 85 (8%) X-linked recessive, and 7 of 85 (8%) not classified by mode of transmission.
