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.

Conjunctival hyperemia is a conjunctival reaction that appears as dilation and redness of the conjunctival vessels. The pattern of hyperemia often appears with the greatest redness at the fornices and fades moving toward the limbus.

Is vernal keratoconjunctivitis curable?

Vernal keratoconjunctivitis (VKC) generally resolves spontaneously after puberty without any further symptoms or visual complications. However, the development of corneal ulcers (in approximately 9.7% of affected individuals), cataract or glaucoma can potentially cause permanent vision loss.

Is Pataday a mast cell stabilizer?

Olopatadine 0.01% (Patanol and Pataday) possesses antihistaminic activity and mast cell stabilizing effects.

What is conjunctival lymphoma?

Lymphoma is a malignant lymphoproliferative tumor that can involve the conjunctiva. Approximately 5-15% of all extranodal lymphomas are found in the ocular adnexal region, with approximately 25% of those involving the conjunctiva. Ninety-eight percent of conjunctival lymphomas arise from B-lymphocytes.

Can you see the conjunctiva?

Conjunctiva Of The Eye. An important structure on the surface of the eye is one you can’t easily see — it’s called the conjunctiva.

What is filamentary keratitis?

Filamentary keratitis is a condition in which strands (“filaments”) composed of degenerated epithelial cells and mucus develop on and adhere to the corneal surface causing pain and foreign body sensation.

Does scleritis affect vision?

If it’s not treated, scleritis can lead to serious problems, like vision loss. It also can be linked to issues with your blood vessels (known as vascular disease).

How common is TSPK?

Conclusion: TSPK is a rare, relapsing corneal disease with the onset mostly in the first and third decade of life. TSPK is mostly bilateral, but may be also unilateral and findings are asymmetrical in almost all cases.
