Macular hard drusen in the right eye. 65-year-old diabetic woman. Drusen, from the German word for node or geode (singular, "Druse"), are tiny yellow or white accumulations of extracellular material that build up between Bruch's membrane and the retinal pigment epithelium of the eye. The presence of a few small ("hard") drusen is normal with ...
Retinitis pigmentosa (RP) is a member of a group of genetic disorders called inherited retinal dystrophy (IRD) that cause loss of vision. [1] Symptoms include trouble seeing at night and decreasing peripheral vision (side and upper or lower visual field). [1] As peripheral vision worsens, people may experience "tunnel vision". [1]
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.
If your whole eye has gone red, learn about the causes of bloodshot eyes and how to fix them. Weirdly enough, a red spot on eye might have a cause totally unrelated to your eyes: sneezing or coughing.
The difference between the two forms is categorized by the change in the macula. Those with dry form AMD have drusen, cellular debris in their macula that gradually damages light-sensitive cells and leads to vision loss. In wet form AMD, blood vessels grow under the macula, causing blood and fluid to leak into the retina. [4]
Diabetic retinopathy (also known as diabetic eye disease) is a medical condition in which damage occurs to the retina due to diabetes.It is a leading cause of blindness in developed countries and one of the lead causes of sight loss in the world, even though there are many new therapies and improved treatments for helping people live with diabetes.
A green filter ~540–570 nm is used to block out red wavelengths of light. This allows a better contrast for viewing retinal blood vessels and associated hemorrhages, pale lesions such as drusen and exudates, and subtle characteristics such as nerve fibre layer defects and epiretinal membranes. [12]
Lin-Manuel Miranda is "still surprised" that "We Don't Talk About Bruno" was the runaway hit from Encanto.That's why he's hesitant to guess what could be the fan-favorite song from Mufasa: The ...
