Inherited retinal detachment.

Patients with retinal detachment and their relatives with the same disease (Group F) are compared to a group of unselected cases of retinal detachment from the Swedish population (Group C). The prevalence of bilaterality is greater in Group F. The age-distribution shows younger patients. Myopic refraction is common. More cases with aphakia, lattice degeneration and large tears are found. All these differences are highly significant. Multiple retinal holes are also significantly more common in Group F. After operation, healing is achieved in 78.8% which is not significantly different in comparison with the cure rate in Group C. (83.4%).
