What is membrane conjunctivitis?

Introduction. 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 causes membranous conjunctivitis?

Streptococcus pyogenes and Corynebacterium diphtheriae are the most common causes of membranous conjunctivitis. In diphtheritic conjunctivitis, there is formation of true membrane, when peeled blood oozes out from conjunctival surface. Streptococcus pyogenes infection of the eye resembles ligneous conjunctivitis.

What is serous conjunctivitis?

What is pseudo membrane?

A pseudomembrane is a thin yellowish-white membrane seen in the fornixes and palpebral conjunctiva that can be easily peeled off leaving an intact underlying epithelium. 1 Corynebacterium diphtheriae, Neisseria gonorrhoeae, Streptococcus pyogenes and adenovirus are the commonly isolated micro-organisms in such cases.

How is pseudomembrane removed from the eye?

Removing pseudomembranes has shown to dramatically reduce symptoms and shorten the normal course of viral conjunctivitis. The doctor will instill some anesthetic eye drops to numb the eye. With a cotton tip applicator or stainless steel forceps, the doctor will remove the pseudomembrane.

What is chemical conjunctivitis?
