Fundus of geographic atrophy. Geographic atrophy (GA), also known as atrophic age-related macular degeneration (AMD) or advanced dry AMD, is an advanced form of age-related macular degeneration that can result in the progressive and irreversible loss of retinal tissue (photoreceptors, retinal pigment epithelium, choriocapillaris) which can lead to a loss of central vision over time.
Geographic atrophy (also called atrophic AMD) is an advanced form of AMD in which progressive and irreversible loss of retinal cells leads to a loss of visual function. There are multiple layers that make up the retina, and in geographic atrophy, there are three specific layers that undergo atrophy: the choriocapillaris, retinal pigment ...
Lampalizumab is an antigen-binding fragment of a humanized monoclonal antibody that binds to complement factor D; it was developed as a potential treatment of geographic atrophy (atrophy of the retinal cells, retinal pigment epithelium, and choriocapillaris) secondary to age-related macular degeneration.
Gildeuretinol is an investigational new drug being developed by Alkeus Pharmaceuticals for the treatment of retinal diseases, particularly Stargardt disease and geographic atrophy secondary to age-related macular degeneration (AMD).
Autoimmune retinopathy (AIR) is a rare immunological disease in which the patient's immune system attacks proteins in the retina, leading to loss of vision.Researchers do not yet fully understand the disease, but it may be the result of cancer or cancer chemotherapy. [1]
Recently, central serous chorioretinopathy has been understood to be part of the pachychoroid spectrum. [5] [6] In pachychoroid spectrum disorders, of which CSR represents stage II, the choroid, the highly vascularized layer below the retina, is thickened and congested with increased blood vessel diameter, especially in the deep choroid (the so-called Haller's layer).
In general, the idea is to bridge geographic barriers and bring cardiovascular care closer to where people are, Longenecker said. African countries have done that to great effect, ...
Focal and multifocal retinal dysplasia appears as streaks and dots in the central retina. Geographic retinal dysplasia appears as an irregular or horseshoe-shaped area of mixed hyper or hyporeflectivity in the central retina. Retinal detachment occurs with complete retinal dysplasia, and is accompanied by blindness in that eye.
