retinitis pigmento´sa a group of diseases, frequently hereditary, marked by progressive loss of retinal response (as recorded by the electroretinograph), retinal atrophy, attenuation of retinal vessels, and clumping of the pigment, with contraction of the field of vision. It may be transmitted as a dominant, recessive, or X-linked trait and is sometimes associated with other genetic defects. It may become manifest at the age of two or three years, or it may follow a slow course over a period of years. There is no successful treatment or cure for the condition. Early diagnosis allows the patient to prepare for the eventual loss of vision.
retinitis proli´ferans a condition that may result from intraocular hemorrhage, with neovascularization and the formation of fibrous bands extending into the vitreous from the retina; retinal detachment may result.
suppurative retinitis retinitis due to pyemic infection.

retinitis proliferans

The extension of new blood vessels and fibrous tissue following bleeding into the VITREOUS body from the RETINA in diabetic RETINOPATHY. This tends to lead to RETINAL DETACHMENT and blinding of the eye. Microsurgical removal of the whole VITREOUS body together with the proliferative tissue is sometimes successful.
