Popis: | Retinitis pigmentosa (RP) is a group of inherited diseases of the retina characterized by progres sive photoreceptor dysfunction associated with cell loss, vessel attenuation and eventual retinal atrophy. Coats' disease is an idiopathic condition, generally unilateral and more commonly affecting males. Telangiectatic and aneurysmal retinal vessels are observed, with intra- and subretinal exudates. These vascular abnormalities may eventually lead to exuda tive retinal detachment and severe visual loss. The observation of Coats' -type changes with long standing RP is well established. 1 - 5 The association does not seem to be either random or coincidental. The age, sex, bilaterality and retinal location in affected patients differ greatly from those seen in classic Coats' disease. The genetics of RP is complex, and the mode of inheritance can be autosomal dominant, recessive, X linked or digenic. We are aware of only three reports of siblings with Coats' -type RP. 1 • 3 • 5 The apparent mode of inheritance was autosomal recessive in two reports, 1 • 3 and in the third case the mode of inheri tance was determined to be autosomal dominant. 1 • 5 To our knowledge, vertical transmission of Coats' -type RP has not been reported. |
