What is Cornea?
The cornea is the clear, protective outer layer of the eye. Its main function is to protect the eyes from germs, dirt and other harmful objects. It has also the capability to filter out the amount of the ultraviolet light coming from the sun. Its curvature refracts the light; thus, providing ⅔ of the eye’s focusing power.
Cornea has three main layers namely epithelium, stroma and endothelium. Its other layers are Bowman’s Layer and Descemet’s Membrane.
What Conditions Affect the Cornea?
There are several diseases and conditions that affect the cornea. These include infections, nutrition diseases, trauma, and autoimmune disorders. Other eye conditions such as dry eye and glaucoma can also damage the cornea.
What are the Symptoms of Corneal Problems?
Though cornea may quickly repair, the person suffering from a corneal problem may experience pain, tearing, blurred vision, and extreme sensitivity to light. Blurred vision usually occurs when the curvature of the cornea is affected. On the other hand, the person experiences pain when the disease affects the nerves in the cornea.
How are Corneal Problems Treated?
The treatment for corneal problems actually depends on the condition but most of the time, it includes medications, surgery or laser treatment.
