Sometimes self-medicating can be difficult.  Symptoms overlap, and there can be various outcomes which can be very confusing. When it comes to your corneas, you want your diagnosis to be clear, and the same goes for finding the issue that relates to it.

Here are some of the common eye conditions relating to your corneas.

Corneal Conditions

Your cornea is usually quick to repair itself. However, certain diseases and conditions can stop it from doing so. If you have symptoms such as blurred vision, pain, scarring, redness, teary eyes, or light sensitivity, then you should seek the advice of an eye doctor.

Here are some of the things that it could be.

Keratitis 

If your cornea is inflamed, then keratitis could be to blame.  If you have keratitis, you may experience pain that is moderate to intense and a grating sensation that impairs your eyesight. Keratitis can enter the eye via injury, causing infection. It is treatable—but the earlier it's treated, the better.

Dystrophy

Although various types of dystrophy could be causing discomfort, some are more common than others.

● Keratoconus can change the shape of your cornea and even cause scarring. 
● Fuch’s Dystrophy causes swelling which gradually affects vision. It usually occurs in both eyes at the same time.
● Map-dot-fingerprint usually develops later in life and takes on the appearance of its namesake, maps dot and fingerprints. Often, it will not cause pain but could result in teary eyes and a sensation that there is something in your eye.
● Lattice Dystrophy occurs when proteins in the stroma. It can affect vision, causing things to seem cloudy. 

Ocular Herpes

A viral infection that can be spotted via sores on the eyelid.  Ocular herpes can also be found on the cornea and worsen if left unattended. As with many herpes, there is no cure, but treatment may shorten the duration of an outbreak.  

Shingles (Herpes Zoster)

Shingles are the same virus that comes from chicken pox. Usually, they cause an irritating skin rash but can also cause corneal discomfort or complications. Ocular complications can occur even months after infection and can spread from touching the virus on your skin, then rubbing your eyes.

If you have experienced this skin rash recently, it might be useful to consult your eye doctor to make sure you are not showing symptoms.

Pterygium

Pterygium is a pink growth found on the cornea, causing some discomfort. Sometimes it will not grow noticeably whereas at other times it can grow over the pupil. It could be the result of excessive exposure to UV rays. Remember to wear sunglasses to avoid this.  Although it might be noticeable, removing a pterygium is not always an urgent procedure, and it can grow back. 

If you recognize any of the symptoms mentioned or are just experiencing discomfort around your cornea, it is always best to consult an expert. Some eye diseases and complications are more severe than others. It is always best to find out which category yours falls into.
