Cornea

The cornea, positioned just in front of the iris and pupil, constitutes the eye’s anterior surface, enabling the admission of light into the eye.

The cornea is the clear, dome-shaped front surface of the eye that acts as a protective layer and helps to focus light onto the retina.

It plays a vital role in vision. Various conditions can affect the cornea, leading to vision problems.

Causes of Corneal Conditions:

● Corneal Injuries: Trauma or injury to the eye, such as
scratches, cuts, or foreign bodies, can damage the cornea.
● Infections: Bacterial, viral, or fungal infections can affect
the cornea, leading to conditions like keratitis.
● Corneal Dystrophies: Genetic conditions can cause
abnormal changes in the cornea, such as Fuchs’ dystrophy
or lattice dystrophy.
● Corneal Ulcers: Open sores on the cornea, often caused
by infections or severe dry eye, can lead to ulcers and
vision impairment.
● Keratoconus: This condition involves the thinning and
bulging of the cornea, resulting in distorted vision.
