What Causes Bloodshot Eyes?
6. Blepharitis
Blepharitis is one of the commonest conditions that affect the eyes. Symptoms include bloodshot eyes, crusting of the eyelid, itching, burning, light sensitivity, blurry vision, and a gritty sensation.
Blepharitis occurs due to the inflammation caused by bacteria in the congested meibomian oil glands. These glands are located at the base of each eyelash. Other conditions that may cause blepharitis are staphylococcal dermatitis, herpes simplex dermatitis, contact dermatitis, rosacea, molluscum contagiosum, and more. Diagnosis can be achieved via an examination under a slit lamp. Other beneficial investigations include a culture of the debris collected from the eye. Blepharitis can be treated by washing of the eyelid, eyelid scrubs, warm compresses, eyelid massages, topical antibiotics, and topical steroids. A low dose of oral antibiotics may be prescribed.
