Corneal Disorders
The cornea is a clear and protective dome-shaped covering over the iris (coloured part of the eye) and the pupil (small central black circle in the iris) of the eye is made up of three main layers, namely the epithelium, stroma, and endothelium.
The cornea acts as a lens and helps in projecting light onto the retina (light-sensitive layer at the back of the eye). A damaged or diseased cornea may change shape, reduce transparency of the cornea, and result in impaired vision.
The most common causes of corneal disorders include:
- Eye injuries or corneal damage caused by previous eye surgery
- Keratitis (corneal inflammation due to bacterial or fungal infections)
- Fuchs’s dystrophy (destruction of the lower corneal layer)
- Corneal dystrophies (diseases that cause structural problems with the cornea) such as:
Keratoconus (change in the corneal curvature) - Herpes zoster Ophthalmicus (viral herpes infection of the eye)
- Map-Dot-Fingerprint dystrophy (abnormal growth of membrane between the upper and middle corneal layers)
- Lattice dystrophy (abnormal protein deposits on the middle corneal layer)
Mild damage to the cornea may heal over time, while severe injuries may result in permanent damage to the cornea causing a serious eye problem.
Consult our team of eye surgeons if you experience redness, pain, blurred vision, irritation or light sensitivity. Our specialists will conduct a thorough eye examination to diagnose the corneal disease.
Corneal disorders can be treated with medications, corneal transplantation, and corneal laser surgery.
