Keratoconus is a condition where the cornea, the clear front surface of the eye, gradually becomes thinner and bulges outward into a cone-like shape. This change in shape distorts vision, causing blurriness, sensitivity to light, and difficulty seeing clearly, especially…
Color blindness, also known as color vision deficiency, is a condition where a person has difficulty distinguishing certain colors. It usually results from genetic factors affecting the cone cells in the retina, which are responsible for detecting color. While there…
Blindness often develops gradually, and recognizing its early warning signs can be crucial for timely treatment and prevention of further vision loss. The warning signs of blindness can vary depending on the underlying cause, but there are several common symptoms…
Retinal detachment happens when the retina, which is the thin, light-sensitive layer of tissue lining the back of the eye, pulls away from its normal position. This separation disrupts the retina’s ability to function properly, cutting off its supply of…
Diabetic retinopathy is a serious complication of diabetes that affects the blood vessels in the retina, leading to potential vision loss if not properly managed. The condition progresses through several stages, from mild non-proliferative diabetic retinopathy to more severe proliferative…
Macular degeneration is a progressive eye disease that primarily affects the macula, the central part of the retina responsible for sharp, detailed central vision. This condition is most common in people over 50 and is a leading cause of vision…
Cataracts form when the clear lens inside your eye becomes cloudy, which blocks or distorts light passing through to the retina, causing vision to blur. The primary cause of cataracts is **aging**. As you get older, the proteins in the…
Glaucoma is a group of eye conditions that damage the optic nerve, often due to increased pressure inside the eye. While there is no cure for glaucoma, there are multiple treatments available that aim to lower intraocular pressure (IOP) to…
Vertigo is a distinct sensation where you feel as if you or your surroundings are spinning or moving, even when everything is still. It’s important to understand that vertigo itself isn’t a disease but rather a symptom indicating an issue…
Ménière’s disease is caused primarily by abnormal fluid buildup in the inner ear, specifically in a part called the endolymphatic sac and duct. This fluid, known as endolymph, normally helps with hearing and balance by cushioning and transmitting sound and…
