What is the corneal ulcer?
The corneal ulcer is an open lesion that appears on the eye. Ulcers can be caused by viral, bacterial or fungal infections and often results in eye pain and pus. Without rapid medical treatment, the corneal ulcer may permanently damage the vision of a person. It is important to visit an emergency room or ophthalmologist as soon as possible to get the right diagnosis and find out which drugs can help alleviate symptoms and support healing. Doctors can also provide useful information on how to prevent future eye infections. Scratching or injection on the cornea leaves the eye susceptible to bacterial infections. People who wear contact lenses are exposed to a higher risk of ulcers, as the lens can irritate the eye bacteria and capture the bacteria in the cornea. A ulcer may also be a viral infection such as herpes simplex virus or a sponge. Less commonly common, vitnedostatek amin can weaken the cornea and make the immune system less effective in fighting bacteria.
The most common symptoms of corneal ulcer are redness, excessive tears and constant pain. The infection deteriorates, the lower lid can be swollen and the milk pus can build and drain from the eye. The vision often becomes blurred and one can develop headaches and feelings of nausea. The ulcer, which is left untreated, can actually scare the cornea and cause permanent loss of sight.
A person who believes that he could have a corneal ulcer should immediately seek medical care. After the initial inspection in the emergency room or the ophthalmologist's office, the doctor uses a specialized microscope to carefully explore the ulcer. If it is not clear what caused the lesion, the doctor collects a tissue sample for laboratory analysis. Laboratory tests can detect the ppiration of bacteria, viruses or mushrooms and help doctors determine the proper course of treatment.
corneal ulcers are usually easy to treat with eye drops and oral drugs thatThey contain antiviral, antibacterial or antifungal agents. By using drops daily and preventing excessive exposure to bright light, the ulcer usually recovers in less than three weeks. A patient wearing contacts could be instructed to wear glasses instead of healing. In addition, the physician may explain the importance of removing contacts before bedtime and proper lens cleaning procedures that help reduce the risk of repeating eye ulcers.
