Marginal keratitis is a disease of eye characterized by inflammation of outer edge of cornea. Cornea is a clear and transparent front portion of the eye. It is dome shaped tissue which lies directly in front of the iris and pupil. Light enters through cornea and passes inside the eye. Almost 70 percent of focusing power is provided by cornea.
Cornea is an important structure in the anterior segment of the eye. It is a transparent tissue in front of the eye surrounded in the periphery by the white (sclera) of an eye.
Patient suffering from marginal keratitis may develop following symptoms:
- Formation of crusts on the margin of eyelids and white flakes like dandruff at the base of eyelashes. These are prominent symptoms of blepheritis which in most cases is the cause for marginal keratitis.
- Scratchy feeling in the eye as if presence of some foreign body in the eye.
- Redness and watering
- Severe irritation in the eye
- Discharge of mucus from the eye.
- Increased light sensitivity and photophobia.
Marginal keratitis is diagnosed with the help of slit lamp. It is an instrument used by ophthalmologists to examine the eye. Once detected, treatment consists of addressing the bacterial infection in the eyelids as well as warm compresses and eyelid massage. Eyelid hygiene is of great value when treating blepheritis. Here is simple procedure that can be used:
- Warm compresses: Soak a cotton ball in warm water. Wring out excess of water and gently use slight pressure to clean the margin of the closed eyelid. Warm compress helps to clear off the dandruff from the lashes and also removes the blockage of the oil glands.
- Eyelid massage: Massage your eyelids with your index finger in circular motion. It will remove the blockage of the oil glands in the periphery of the eyelids.
- Eyelid scrubbing: A cotton bud is dampened in warm water. The edges of eyelid are cleaned with the bud. At the same time, dandruff at the base of eyelashes is also removed.
Along with the above treatment measures, antibiotic eye drops and steroid eye drops are used every 5 hourly to reduce inflammation of the cornea and for quick recovery from the illness.
