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.
Symptoms: Lattice degeneration itself does not cause symptoms: Diagnostic method: The only way to diagnose the condition is with a dilated fundus examination by an eye care provider. A dilated fundus examination is done by administering dilating eye drops in your eyes to expand the pupil so that the retina can be carefully evaluated.
[1] [2] [3] It may start in a small area, but without quick treatment, it can spread across the entire retina, leading to serious vision loss and possibly blindness. [4] Retinal detachment is a medical emergency that requires surgery. [2] [3] The retina is a thin layer at the back of the eye that processes visual information and sends it to the ...
Incipient atrophy is demarcated by areas of retinal pigment epithelium (RPE) thinning or depigmentation that precede geographic atrophy in the early stages of AMD. In advanced stages of AMD, atrophy of the RPE (geographic atrophy) and/or development of new blood vessels (neovascularization) result in the death of photoreceptors and central ...
Treatment is based on the cause of the retinopathy and may include laser therapy to the retina. Laser photocoagulation therapy has been the standard treatment for many types of retinopathy. Evidence shows that laser therapy is generally safe and improves visual symptoms in sickle cell and diabetic retinopathy.
The built-up deposits dry out and thin the macula. Conversely, wet macular degeneration occurs when abnormal blood vessels develop under the retina and macula. Often, these blood vessels leak ...
A vitreo-retinal specialist (an ophthalmologist specialized in treatment of retinal diseases) should be consulted for proper management of the case. [ citation needed ] Presumed ocular histoplasmosis syndrome and age-related macular degeneration (AMD) have been successfully treated with laser, anti-vascular endothelial growth factors and ...
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]
