Bacterial Conjunctivitis Vs other causes

Bacterial Conjunctivitis Vs other causes

A clinical scoring system has been developed to distinguish bacterial from other causes of conjunctivitis in healthy adults who did not wear contact lenses. 

A score of +5 to −3 is determined as follows:

~ Two glued eyes (+5); one glued eye (+2); history of conjunctivitis (−2); eye itching (−1).

~ A score of +5, +4, or +3 is useful in ruling in bacterial conjunctivitis with specificities of 100%, 94%, and 92%, respectively.

~ Scores of −1, −2, or −3 are useful in ruling out bacterial conjunctivitis with sensitivities of 98%, 98%, and 100%, 

respectively.

Allergic conjunctivitis is typically bilateral and accompanied by eye itching. Giant papillary conjunctivitis is a type of allergic reaction, most commonly to soft contact lenses
