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

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]

All cases were evaluated to identify possible risk factors for the development of CMV retinitis. The immune status of all screened cases was evaluated and classified: nil immunodeficiency, prematurity, congenital immunodeficiency syndrome, perinatal vertical HIV exposure, HIV-positive organ transplantation, chemotherapy or other.
CMV retinitis and other posterior segment manifestations were seen only in patients with <50 cells/uL.
The frequency of strabismus was observed in 42 (27.6%) patients, cataract in 39 (25.6%) patients, extreme myopia in 32 (21.1%) patients 13 (8.5%) persons of microphthalmia, 8 (5.3%) individuals with anophthalmia, 9 (5.9%) patients of astigmatism and 6 (3.9%) patients of nystagmus, while keratoconus, glaucoma and retinitis pigmentosa were observed in single patient (0.7%)each.
In 2014, RST-001 received an Orphan Drug Designation by the US FDA for the treatment of Retinitis Pigmentosa.
* The report provides a snapshot of the global therapeutic landscape of Retinitis Pigmentosa (Retinitis)
The X-linked form of retinitis pigmentosa is an ideal candidate for a precision medicine approach because a common mutation accounts for 90 percent cases.
Eye examination using tracking laser tomography (Spectralis, Heidelberg Engineering Inc., Germany) revealed a typical presentation of HCMV bilateral retinitis, characterized by focal hemorrhages, exudates in both eyes, and thinning, and disorganization of the retinal layers (Figure 1).
The aim of the present study was, first, to replicate the previous work on retinitis pigmentosa-related sleep disturbances (Gordo et al., 2001; Ionescu et al., 2001) and to determine whether individuals with other retinal disorders experienced similar problems.
Retinitis pigmentosa -- the most common cause of blindness in young people -- occurs mostly due to loss of millions of light sensitive photoreceptor cells that line the retina, Medical Xpress reported.
