Retinal remodeling during retinal degeneration
Experimental Eye Research, 2005Retinal degenerations, regardless of the initiating event or gene defect, often result in a loss of photoreceptors. This formal deafferentation of the neural retina eliminates the intrinsic glutamatergic drive of the sensory retina and, perhaps more importantly, removes coordinated Ca++-coupled signaling to the neural retina.

OUTER RETINAL TUBULATION IN RETINAL DYSTROPHIES
Retina, 2017To evaluate the occurrence and characteristics of outer retinal tubulation (ORT) in an Indian population with retinal dystrophies.In this retrospective study, 309 eyes of 157 patients with retinal dystrophies including retinitis pigmentosa (RP, 183 eyes), Stargardt disease (STGD, 93 eyes) and Best disease (33 eyes) were reviewed.

Retinal Metastasis Simulating Cytomegalovirus Retinitis
Ophthalmic Surgery, Lasers and Imaging Retina, 2012A 62-year-old man with lung cancer presented with a 2-week history of decreased vision and clinical features of cytomegalovirus retinitis. The patient was empirically treated for viral retinitis, but microbiological testing of the vitreous fluid was negative.

Retinal Detachments in Patients With Cytomegalovirus Retinitis
Archives of Ophthalmology, 1991Retinal detachments are a recognized complication of cytomegalovirus retinitis. In a series of 145 patients with cytomegalovirus retinitis, 38 (26%) developed retinal detachments. The cumulative probability of a retinal detachment 1 year after the diagnosis of cytomegalovirus retinitis was 50%.

Tubercular Retinitis and Retinal Vasculitis
2017Tuberculosis (TB) has traditionally been considered a disease of the uveal layers, especially the choroid. However, retinal involvement, typically retinal vasculitis, affects a large subgroup of patients presenting with ocular TB. Though recognized more than a century ago (Axenfeld and Stock, Uber die Bedeutung der Tubrtculose in der Aetiologie der ...

Rhegmatogenous retinal detachments with cytomegalovirus retinitis
Current Opinion in Ophthalmology, 1998The most important ocular opportunistic infection in patients with AIDS is cytomegalovirus (CMV) retinitis. Management of CMV retinitis has become complex, as the life expectancy of many patients has increased exponentially. Most retinal detachments in CMV retinitis are rhegmatogenous in nature. Because of atrophic changes in the retina and alterations

Retinal Aneurysms in Adult Cytomegalovirus Retinitis
American Journal of Ophthalmology, 1978We observed aneurysms of the retinal arteries, capillaries, and venules occurring in a patient with cytomegalovirus retinitis. These aneurysms were caused by involvement of the retinal vascular endothelium resulting in focal weaknesses in the vascular walls. The clinical appearance of this retinitis superficially resembled retinal branch vein occlusion.

Retinal Pathology in Retinitis Pigmentosa
1995Retinitis pigmentosa (RP) causes primary degeneration of photoreceptors, followed by reactive changes in the retinal pigment epithelium (RPE) and Muller glia, death of inner retinal neurons, and atrophy of the retinal vasculature. Current strategies for retinal therapy include transplantation of normal photoreceptors, delivery of corrective genes to ...

Retina, 1984
A healthy-appearing male patient presented with signs of unilateral fibrinous iritis, necrotizing retinitis, retinal vasculitis, and vitritis, suggestive of a herpesvirus retinitis or acute retinal necrosis syndrome (ARN). The patient, an active homosexual, withheld the details of his sexual history, portraying himself as exclusively heterosexual. With

Retinal Detachment with Retinal Dialysis
1989Retinal dialyses have been observed in chronic pars planitis as a result of cyclitic membrane contraction1 in retinal detachment following penetrating ocular wounds2,3 and after pars plana vitrectomy. Most cases, however, occur either after ocular contusion or as a primary disease in young individuals.
