Learn everything about the corneal disease and its symptoms, causes, and treatments. Recover well from the vision problems brought about by a damaged cornea.
The cornea is the defensive layer of the eye that shields it from external dust and other vision impediments. It works with the sclera to shield the eye from any pollutants or external infections by coating the eyeball. It is an equally effective barrier that shields the eye from excessive UV light from the sun.
The main function of the cornea is to regulate the light entering through the pupil. By bending or refracting the light, it helps the person to focus on the object. This way, the person can see the object clearly.
This important function can be impeded if there is any damage or issue to the cornea. It can also result in poorer eyesight.
There are quite a few reasons for corneal disease. Some of the most common causes include tissue degeneration or genetic disposition. It can also be brought on by external infections.
If you or your loved one faces such an issue, it is wise to consult an ophthalmologist for an urgent check-up. The expert will be able to correctly diagnose the problem. This way, you can undergo the most suitable treatment type to restore clarity in vision.
Symptoms and Causes of Corneal Disease:
In case there is a minor injury to the cornea, it tends to recover on its own. It is quite likely that you may feel some pain or redness in the eye during this phase. But it is vital to note that such redness or pain can also be associated with other types of problems in the eye. Since you won’t be able to determine the exact problem with these symptoms, it is better to get the eye checked by an expert ophthalmologist.
Some of the main causes of corneal disease are as below:
- Keratitis: Viruses, bacteria, or chemicals infecting the cornea can lead to the condition known as keratitis
- Ocular Herpes: The Herpes Simplex HSV-1 virus can attack the cornea leading to ocular herpes.
- Keratoconus: In this condition, the cornea may not function as intended. It thins and gradually bulges outward, thereby causing refractive errors and resulting in blurry vision.
- Corneal Dystrophies: There are wide varieties of corneal dystrophies which can cause structural problems in the cornea.
- Trauma or Injury
- Foreign objects entering the eye such as dirt, sand, sawdust, and chemicals
- Lack of proper care after a medical procedure
Treatments for Corneal Disease:
An ophthalmology expert will recommend the right course of treatment to rectify any problems with the cornea. Such treatments are simple and often involve the use of medication. You may be given medicated eye drops to treat the condition.
It is possible that the eye expert may recommend putting on an eye patch to counter the glare of light or heat entering the eye during the treatment process.
It may take a few days to recover from the corneal disease. If the severity of the condition is intense, then you may expect the treatment and recovery to take a few more weeks than expected.
Throughout the duration of treatment and recovery, the patient needs to take utmost care of the eyes. He should not rub his eyes or put on contact lenses. Some corneal conditions cannot be rectified at home but may need you to get admitted. These include options like laser procedures like phototherapeutic keratectomy.
In rare cases, severe corneal degradation may call for a total transplant of the cornea. In such procedures, the patient gets healthy tissue in place of the degenerated cornea.
