Keratoconus is a progressive eye condition in which the normally round cornea (the clear, dome-shaped surface that covers the front of the eye) becomes thin and bulges out into a cone-like shape. This distortion affects how light enters the eye, leading to blurry or distorted vision.
It is commonly associated with high irregular astigmatism which causes
Blurry or distorted vision
Increased sensitivity to light and glare
Difficulty seeing at night
Frequent changes in glasses prescriptions
Double vision in one eye
It is often associated with excessive eye rubbing. The condition often worsens over time, especially in the teenage years and early adulthood.
The exact cause of keratoconus is not fully understood, but a combination of genetic and environmental factors is thought to play a role. Family history, eye rubbing, and certain conditions like allergies may increase the risk.

Fuchs' Dystrophy is a condition that affects the cornea, which is the clear, dome-shaped surface at the front of your eye.
The back surface of the cornea is lined by cells (called endothelial cells) which pump fluid out of the cornea to keep it clear. In Fuchs dystrophy these cells slowly die off , causing fluid build up in the cornea. The resulting corneal swelling affects its transparency and distorts light rays entering the eye, causing blurriness of vision.
People who have the condition may not notice symptoms until they are in their 50s or 60s. The condition may worsen slowly over time. It usually affects both eyes.
Pterygium is a fleshy growth of the conjunctiva , which is the thin transparent membrane covering the white of the eye. A pterygium typically starts on the side of the eye near the nose and can extend onto the cornea.
Excessive and repeated exposure to sunlight, dust, and wind irritates the conjunctiva and causes it to grow over the cornea.
It can cause
Redness and irritation in the affected eye
Dryness or a burning sensation
Blurred vision if the pterygium grows over the cornea and affects the central
Pterygia are generally not harmful to overall health but can cause discomfort and vision issues if they grow significantly. Early detection and preventive measures, such as protecting the eyes from UV light by wearing sunglasses with UV protection and wide brimmed hats are key to managing the condition.
