Corneal blindness accounts for 0.52% of total blindness in the Indian subcontinent.The cornea can be the site of various disorders. At Abhinam Eye Centre, we have a dedicated team of cornea specialists committed to provide you with the best possible care to protect your vision.
The eye is like a camera in which lenses focus the picture on a light sensitive film. In the human eye, the transparent cornea and lens focus light on the retina, which changes it into electrical signals. These signals are then transmitted to the brain by the optic nerveto be perceived as images.
Foreign Bodies, Corneal Abrasions & Injuries
Since the abundant nerve supply of the cornea makes it one of the most sensitive parts of the body, it serves as an excellent “watchdog” for foreign material entering the eye. Dirt or specks lodging in the eye may produce scratching, knife-cutting sensations that the sensitive corneal nerves transmit to the brain. Foreign bodies may embed in the cornea. A foreign body on the cornea needs urgent attention by an ophthalmologist. One should not attempt to remove it by rubbing the eye.
A twig of a tree, a piece of paper, or a fingernail can produce corneal abrasions. If not attended to immediately, secondary infection can occur which could lead to vision-threatening complications.
Injuries to the eye with sharp or blunt objects require urgent attention of your ophthalmologist, especially to rule out corneal injuries,which can be sight-threatening.
Acid or alkaline solutions splashed into the eye may be potentially sight threatening. Symptoms (such as pain, redness, watering and light-sensitivity) occur immediately after exposure to the chemical and may be severe in nature..
Inflammation of the cornea, or keratitis, may be secondary to conjunctivitis, blepharitis (inflammation of eyelid margins), or injury. Keratitis is characterized by a painful red eye, sensitivity to light, and an occasional scratching sensation upon blinking. An ulcer may develop in the cornea after a bacterial, viral, fungal, or other infectious organisinvades its outer layer.
This grayish elevated growth of elastic and connective tissue containing blood vessels invades and grows over the cornea. It may result from irritation to the eye from wind, heat of the sun, dust, or smoke. If the pterygium progresses to grow over the center of the cornea, sight may be impaired or even lost. Before this occurs, the pterygium should be removed surgically. At our centre, pterygium is removed by a specialized technique called Conjunctival Autografting, where, the pterygium is excised, and a conjunctival graft, taken from a healthy part of the same eye is used to cover the defect.
What is Dry Eye Syndrome?
Dry eye syndrome is a leading cause of ocular discomfort affecting millions of people. Dry eye conditions are a spectrum of disorders with varied etiology ranging from mild eyestrain to very severe dry eyes with sight threatening complications.
