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
● Keratoconus: This condition involves the thinning and
bulging of the cornea, resulting in distorted vision.
