Inherited retinal diseases are a group of hereditary diseases of the eye that lead to progressive loss of sight from photoreceptor cells in the retina becoming damaged and eventually dying. Patterns of inheritance are varied and the blindness-causing genes can be dominant, recessive or x-linked. Collectively, these diseases are the primary cause of blindness in the working age population.

Retinitis pigmentosa accounts for about half of all cases of inherited blindness. Typically, retinitis pigmentosa manifests itself with night blindness and loss of peripheral vision leading to "tunnel vision".

A range of other diseases cause the remaining cases of inherited blindness. Some of these also occur along with other conditions. For example, Usher Syndrome involves both loss of sight and loss of hearing.
