retinitis

 [ret″ĭ-ni´tis]
inflammation of the retina.
retinitis circina´ta (circinate retinitis) circinate retinopathy.
cytomegalovirus retinitis opportunistic infection of the retina by cytomegalovirus, seen in immunocompromised patients; symptoms include retinal necrosis and hemorrhage, leading to blindness.
exudative retinitis exudative retinopathy.
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 proli´ferans , proliferating retinitis a condition sometimes due to intraocular hemorrhage, with neovascularization and the formation of fibrous tissue extending into the vitreous from the retinal surface; retinal detachment may be a sequel.

[retina + G. -itis, inflammation]

retinitis

Inflammation of the RETINA.

retinitis 

Inflammation of the retina. This usually follows inflammations of the vitreous body, retinal vessels and especially of the choroid. Retinitis leads to an exudation of cells into the vitreous body and, if serious, vision will be affected. If the inflammation affects the macular area there will be a loss of central vision. Haemorrhages and oedema (producing a blurring of the margins of the optic disc) are also usually present. See retinal necrosis.

ret·i·ni·tis

(ret'i-nī'tis)
Inflammation of retina.
[retina + G. -itis, inflammation]

retinitis (ret´inī´tis),

n a condition in which the retina becomes inflamed.

retinitis

inflammation of the retina. Occurs in association with many viral infections, particularly canine distemper, scrapie, classical swine fever (hog cholera) and rabies.

neurotrophic retinitis
caused by infection such as canine distemper virus.
retinitis pigmentosa
a group of diseases in humans, frequently hereditary, marked by progressive retinal atrophy, attenuation of retinal vessels, and clumping of the pigment, with contraction of the field of vision. See progressive retinal atrophy.

In the first, the self-reported sleep problems of individuals with retinitis pigmentosa were examined and, in the second, an attempt was made to determine if those who have a genetic mutation that causes their visual disorder but is also expressed in the pineal gland are more likely to experience sleep-related difficulties than those whose mutation is expressed only in the retina.
