Probably the Best Eye Hospital in Hyderabad to provide the Corneal Transplants.
The cornea is a clear, transparent structure just like our watch glass in the front part of the eye. It plays a key role in vision. As light enters the eye, it is refracted, or bent, by the outside shape of the cornea. The curvature of this outer layer helps determine how well your eye can focus on objects close-up and far away.
There are three main layers of the cornea:
Epithelium. This is the most superficial layer of the cornea. It absorbs oxygen and nutrients from tears.
Stroma. The stroma is the middle and thickest layer of the cornea which is made up mostly of water and proteins that give it an elastic but solid form.
Endothelium. The endothelium is a single layer of cells on the very back of the stroma. The aqueous humor is the clear fluid found in the front chamber of the eye and that is in constant contact with the endothelium. The endothelium works as a pump, expelling excess water back into the eye as it is absorbed into the stroma. Without this specialized function, the stroma would become waterlogged, creating a hazy and opaque cornea and reducing vision.
The term "corneal disease" refers to a variety of conditions that affect mainly the cornea. These include infections, degenerations, dystrophy, trauma, etc.
Cornea can be affected in a variety of disorders and the common symptoms the patient complaint are:
Extreme sensitivity to light
Although these symptoms may occur with many other types of eye problems, they may indicate a more serious problem or require special treatment. Therefore, if you experience any of these symptoms, seek care from an eye doctor.
How Are Cornea Problems Diagnosed?
Cornea problems can only be diagnosed after a thorough exam by an eye doctor.
Can Cornea Problems Be Prevented?
Infectious corneal disease caused by bacteria and viruses can be prevented by protecting the eye from injury and limiting physical contact with people who have contagious forms of conjunctivitis. Avoid sharing eye makeup, contact lens solution, contact lens cases, and eye drops with people who are infected and wash your hands thoroughly with soap and warm water for at least 15 seconds after contact with an infected person. Avoid sleeping in contact lenses even if they are FDA approved for that. Sleeping in contact lenses significantly increases the risk of corneal infections.
Although corneal disease resulting from hereditary factors (like dystrophies) cannot be prevented, vision can be preserved with early detection and treatment.
What common conditions can damage the cornea ?
Keratitis is an inflammation of the cornea that sometimes occurs with infection after viruses, bacteria, or fungi enter the cornea. These microorganisms can enter the eye after superficial or deep injuries, causing infection, inflammation, and ulceration of the cornea. Though uncommon, this type of infection can also arise after injury from wearing contact lenses.
Symptoms of keratitis include:
Extreme sensitivity to light
Treatment usually includes antibiotic or antifungal eye drops. Sometimes, antiviral drugs and steroid eye drops are necessary.
