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

Venous eczema

Venous eczema  occurs as a result of venous hypertension causing fluid to collect in the tissues. The stasis of this fluid in the soft tissues results in activation of the innate immune response and subsequent inflammation. Venous eczema has the following clinical characteristics: ·          Itchy red, blistered and crusted  plaques ; or dry fissured and  scaly   plaques  on one or both lower legs (commonly mistaken for cellulitis) ·          Atrophie Blanche (white irregular scars surrounded by red spots) ·          Orange-brown patches pigmentation due to haemosiderin deposition ·          Lipodermatosclerosis If you’re not sure if the patient has venous eczema, ask “Is it itchy?” Varicose eczema is often intensely pruritic and this is a common indication for intervention.
