Few Most Common Corneal Problems!

The cornea is the transparent layer of the eye that acts as a protective shield. The cornea, in combination with the sclera, protects the eyes from various harmful microorganisms and particulate matter, including the harmful UV radiations (to some extent). The cornea is made up of three important layers, the Endothelium, Stroma, and the Epithelium.

  1. Endothelium: The inner layer of the cornea, the endothelium helps to maintain a clear vision by removing the excess fluid absorbed by the stroma. The mitochondria-rich single celled layer functions more like a pump.
  2. Stroma: The middle corneal layer is extremely thick (~90% of the total corneal thickness) and composed mainly of proteins and fluids. Like the endothelium, the stroma, too, plays a pivotal role in the normal eye vision.
  3. Epithelium: Being the outermost layer, the epithelium functions as a defensive shield, protecting the eyes from harmful germs, bacteria and any matter that can harm the eye. Most importantly, the epithelium absorbs the essential nutrients and oxygen (present in the tears). The cornea, thus, plays a pivotal role in the normal vision of the eye. However, an injury or an infection can interfere with the corneal functioning, affecting a person's vision as well as giving rise to other complications (the eyes may appear itchy, watery and red. There may also be light sensitivity).

Some of the common cornea problems include

  1. Keratitis: Injury or microbial (bacteria, virus or fungi) infiltration of the cornea can trigger this condition resulting in corneal infection and inflammation. Some of the symptoms characteristic of keratitis include extreme light sensitivity, blurred vision. The inflammation can also result in redness, pain (moderate to severe) and watery eyes. Antifungal, antiviral or steroidal eye drops may provide relief from the associated symptoms.
  2. Shingles (Herpes Zoster): This condition mainly affects people who have suffered from chickenpox. In some cases, the virus though inactive may still be present in the body (in the nerves). However, at a later period, certain factors may trigger its activation. Once active, the virus can affect different parts of the body, including the cornea. Shingles can cause corneal soreness and inflammation. Old people and those with a weak immunity are more likely to suffer from shingles. People with shingles may benefit from the administration of steroidal (tropical) and antiviral eye drops.
  3. Ocular Herpes: This is a viral infection triggered by Herpes Simplex Virus I (HSV I) or Herpes Simplex Virus II (HSV II) resulting in herpes of the cornea. The condition gives rise to corneal inflammation and sores. Here too, the patient can get some relief by using antiviral or steroidal eye drops.
  4. Keratoconus: This is a degenerative disorder of the cornea that results in thinning of the cornea. The condition can also alter the corneal shape, resulting in swelling, pain, and loss of vision (partial to complete, particularly the night vision).
  5. Fuchs' Dystrophy: This is a corneal dystrophy whereby the corneal endothelial cells break down at a slower rate than usual. As a result, the stroma may be waterlogged resulting in swelling and blurred vision.

Corneal Ulcer - Can It Lead To Blindness?

Antrior most transparent layer of the eye is called cornea. It is an extremely useful layer for refraction and protection of eye. Any trauma, foreign body or chemical etc can invade the integrity of this layer and can be invaded by bacteria, fungus or virus, resulting in the corneal ulcer. Sometimes, due to hypoxia induced by contact lenses too can result in a corneal ulcer.

Depending on clinical presentation, a doctor diagnoses the cause of the ulcer and start the therapy. Since the transparency of cornea is very important, a doctor starts very intensive therapy. With repeated frequent checkups if a proper and intensive therapy is not given, the ulcer can progress and can cause collection of pus in the anterior chamber which if not attended properly, can cause the infection to travel into the interior of the eyeball (vitreous chamber) resulting in total blindness. The ulcer can become deeper and lead to perforation of the cornea, causing severe damage to the eye and may require removal of pus (evisceration) or total removal of the eye ball.


Generally, fungal ulcers are more dangerous and occur mostly in rainy season.

  • It is imperative that a case of corneal ulcer is diagnosed promptly and very intensive treatment proper treatment is given to save the disfigurement of the eye and total irreparable blindness.
  • At times we have not only to give topical drops but oral therapy has to be given. Injections in the eye have to be given. Culture sensitivity has to be done in severe cases to identify the causative organism.
  • In extremely severe cases, we have to perform, therapeutic keratoplasty.

Conclusion: Corneal Ulcer is a serious challenging problem with the potentiality to cause total and irreparable blindness and must be attended promptly by a very expert ophthalmologist to save the eye. In case you have a concern or query you can always consult an expert & get answers to your questions!

Bloodshot Eyes - Causes, Symptoms and Complications

Bloodshot eyes indicate the reddening of the eye vessels. They can cause irritation and make the eye swollen. The condition may arise due to allergies, eye infections, allergies, fatigue and other illness of the eye. It does not signify a disease but indicates an eye condition which might have caused the eye to redden. Bloodshot eyes can be encountered in one or both the eyes.

Causes of Bloodshot Eyes:

One of the frequent causes of bloodshot eyes is irritants such as dry air, pollen, pet dander, dust and UV rays of the sun. Shortage of sleep also tends to make the eyes red. Inflammations of the eye can also make them red giving a bloodshot appearance. It can even happen with people who wear contact lens for more than 16 hours without soaking it in the disinfectant. At times excessive dryness can make the eyes red. Some other reasons for the eye to become red include conjunctivitis, blepharitis, glaucoma and corneal ulcer. Another concerning reason of bloodshot eyes is a subconjunctival haemorrhage. While the latter is not dangerous in nature, it can cause significant trouble if proper care is not taken on time.

Symptoms of Red Eyes:

Some of the common signs of bloodshot eyes include watery eyes, foreign sensation, burning feeling, dermatitis, falling of eye lashes, light sensitivity, swollen eyelid, itching of the eye and feeling of irritation of the eye.

The Complications Involved:

In most of the cases, bloodshot eyes do not imply serious complications. In case it happens from conjunctivitis, a person may not be able to go to work, wear cosmetics and come in public places since it is a communicable disease. If bloodshot eyes arise from a serious condition such as glaucoma and trauma, some of the possible complications may involve the following:

  1. Eye scarring

  2. Vision loss due to complete blindness

  3. Spreading of the existing condition to other persons

  4. Eye loss in severe cases

Preventive Measures:

Bloodshot eyes might arise from an array of reasons. While it cannot be totally dodged, some general preventive measures can ensure that such a condition does not arise:

  1. Keeping hands clean by thoroughly washing them with liquid soap

  2. Not sharing personal belongings such as washcloths, linen, and cosmetics

  3. Get immediate medical attention in case of any eye injuries

  4. Stay away from an environment that is full of allergens

  5. Staying away from people who are suffering from infectious eye diseases such as conjunctivitis

  6. Taking a shower immediately after getting in touch with an infected person suffering from conjunctivitis

  7. Wearing eye glasses in a dusty environment

    If you wish to discuss about any specific problem, you can consult an ophthalmologist.

In spite of repeated frequent checkups, if proper and intensive therapy is not given, the ulcer can progress and can cause collection of pus in the eye (anterior chamber) which if not attended properly, can cause the infection to travel into the interior of the eyeball (vitreous chamber) resulting in total blindness. The ulcer can become deeper and lead to perforation of the cornea, causing severe damage to the eye and may require removal of eyeball also.

Generally, fungal ulcers are more dangerous and occur mostly in rainy season or with a minor trauma also resulting from an injury with a vegetative matter like leaf, wood, plants etc. 

It is imperative that a case of corneal ulcer be diagnosed promptly and very intensive and proper treatment is given to save the disfigurement of the eye and total irreparable loss - blindness.

At times, with topical eye drops, oral therapy also has to be given. Injections in the eye may also be required in severe cases. Culture sensitivity also has to be done in severe cases to identify the causative organism for proper treatment.

In extremely severe cases, we may have to perform, therapeutic keratoplasty.
