What is conjunctivitis and keratoconjunctivitis?

Keratoconjunctivitis is when you have both keratitis and conjunctivitis at the same time. Keratitis is inflammation of the cornea, the clear dome that covers the iris and the pupil. Conjunctivitis is inflammation of the conjunctiva.

What is Pseudomembrane conjunctivitis?

Pseudomembranous conjunctivitis is an inflammatory condition of the conjunctiva characterised by conjunctival injection, mucopurulent discharge and pseudomembrane formation. A pseudomembrane is formed when inflammatory exudate rich in fibrin coagulates on the conjunctiva.

What is Kerato conjunctiva?

Keratoconjunctivitis refers to an inflammatory process that involves both the conjunctiva and the superficial cornea. It can occur in association with viral, bacterial, autoimmune, toxic, and allergic etiologies. This activity outlines the presentation, evaluation, and treatment of keratoconjunctivitis.

Can pseudomembrane go away on its own?

Most cases of viral conjunctivitis are mild and resolve spontaneously within 2 weeks. Severe cases of viral conjunctivitis can cause subepithelial corneal opacities and pseudomembrane formation. Treatment for viral conjunctivitis is generally supportive, with artificial tears and compresses for the eyelids.

What are Subepithelial infiltrates?

Subepithelial infiltrates are small, round and grayish lesions. They are composed of residues of antigen and lymphocyte accumulations adhered to surface stromal cells. The lesions disappear without causing scarring or neovascularization. They are usually bilateral and frequently asymmetrical.

How long do Subepithelial infiltrates last?

This can progress to focal epithelial keratitis and the resulting lesions can last for up to two weeks. After this time period, subepithelial infiltrates (which are thought to be related to the immune response) can form beneath the lesions. These can persist for years and may cause a reduction in visual acuity.
