A corneal ulcer Custom Search A corneal ulcer may be defined as an open sore on the cornea of the eye. The different causes of this condition are bacterial infections in people using contact lenses, viral infections such as infections caused by herpes simplex virus, varicella virus, etc.
Yet other causes include dry eyes, Bell’s palsy, conditions causing loss of sensation of the corneal surface can also promote ulceration or can make people more and more vulnerable to these ulcers. Chemical burns and exposure to different caustic solutions can lead to injuries in the eyes and can promote ulceration of the eyes. Not only this, the people who wear contact lenses are also at an increased risk of getting these ulcers especially when people wear these lenses for extended hours. Contact lenses can damage the corneal surface of the eyes by leading to scratches on the edge of the contact lenses and thus making the cornea of the eye vulnerable to bacterial infections. Additionally, small particles of the eye may get trapped under the contact lenses and can thus lead to scratching of the eyes. Improperly cleaned lenses can also lead to damage to the cornea and may increase the chances of getting an ulcer. Even wearing contact lenses for an extended period of time can also block the oxygen supply to the cornea and thus cornea can become more susceptible to infections and formation of the ulcers. The different symptoms of these ulcers are redness and pain in the eyes, blurred vision, swollen eyelids, etc.
