The cause of SLK is unknown. One of the most common theories suggests that the development of SLK is related to laxity or a loosening of the superior bulbar conjunctiva (the clear layer that covers the eyeball, over the sclera), resulting in friction and inflammation (swelling) between the upper eyelid and the eyeball.

A rare, chronic allergic disease of the cornea and conjunctiva occurring in all age groups, characterized by severe itching and burning sensation, conjunctival injection, photophobia and edema with serious cases leading to ulceration of the cornea which can result in blindness.
What is GPC in eyes?
Giant papillary conjunctivitis (GPC) is when the inside of your eyelid gets red, swollen, and irritated. Without GPC, the inside of your eyelid is very smooth. People who wear contact lenses (especially soft lenses) have the greatest chance of getting GPC.

What is SLK surgery?
When noninvasive or less invasive treatment modalities fail in the treatment of superior limbic keratoconjunctivitis (SLK), surgical intervention is an alternative. Surgical resection of the involved conjunctiva—as delineated intraoperatively by the use of rose Bengal staining—removes the affected tissue.
What produces conjunctiva?
Function. The conjunctiva helps lubricate the eye by producing mucus and tears, although a smaller volume of tears than the lacrimal gland. It also contributes to immune surveillance and helps to prevent the entrance of microbes into the eye.
What is a Chemosis?
Chemosis is swelling of the tissue that lines the eyelids and surface of the eye (conjunctiva). Chemosis is swelling of the eye surface membranes because of accumulation of fluid. This symptom is often related to an allergic response.

EKC is caused by a family of viruses known as adenoviruses that are responsible for an array of respiratory, gastrointestinal, and eye infections. EKC can usually be diagnosed by the red and swollen appearance of the eye, although there are newer tests able to detect the virus by taking a swab of eye fluid.
