Retinitis Pigmentosa

Retinitis pigmentosa (RP) is the term given to a group of inherited rod-cone dystrophies which are characterised by poor night vision, constricted visual fields and typical bone-spicule retinal pigmentation. The commonest mode of inheritance is autosomal recessive (or apparent isolated sporadic cases), which unfortunately tends to be associated with a severe form of the disease. Other less common modes of inheritance include autosomal dominant and X-linked recessive.
