Cornea

What is Cornea?

The cornea is the transparent, dome-shaped surface that covers the front of the eye. It plays a crucial role in focusing vision. Disorders of the cornea can affect vision and eye health significantly. Here’s a comprehensive overview of corneal issues, including symptoms, diagnosis, treatment, risk factors, prevention, and management.

Symptoms of corneal issues

Treatment

Treating corneal issues varies based on the condition's severity and may include

• Prescribed eye drops
• Specialized contact lenses
• Surgical interventions such as corneal transplants to restore clarity and function.

Diagnosing corneal issues

• Eye Exam: A comprehensive examination by an ophthalmologist or optometrist, including a visual acuity test.
• Slit Lamp Examination: A microscope with a bright light used to examine the cornea in detail.
• Corneal Topography: A mapping of the cornea’s surface to identify irregularities.
• Fluorescein Staining: A special dye applied to the eye to highlight damage or abnormalities.
• Microscopy: Examination of corneal cells or tissue samples, if necessary.

Risk Factors

• Genetics: Family history of corneal diseases.
• Infections: Viral, bacterial, or fungal infections affecting the cornea.
