[Familial adenomatous polyposis from the ophthalmologic viewpoint].

Familial adenomatous polyposis is dominant autosomal heritable and pre-cancerous. Characteristic changes of ocular fundus, multiple and bilateral retinal dysplasias, permit diagnosis in presymptomatic stage, significant especially not at least for sporadic cases of polyposis recti and coli, which are 40 per-cent of all. Contrary to often wellknown risk-families this group can't be realized epidemiologically, but complications are the same.
