| pubmed-article:2366452 | pubmed:abstractText | Early diagnosis of retinitis pigmentosa and related diseases is based on a specific history, on perimetry of the outer isopters, and on rod/cone electroretinography. The remarkable variability of phenomenology, age of onset and genetic pattern, however, often complicate early diagnosis. Continuous consulting and documentation of the course of the disease are considered a meaningful care by the physician and represent the basis for the tasks of the geneticist. | lld:pubmed |
