Objective:
To provide a clinical overview of the types of conjunctivitis that are encountered by practicing clinical allergist-immunologists.
Data Sources:
Published literature in peer reviewed journals found in the National Library of Medicine (PubMed) database using the keywords ocular allergy and/or allergic conjunctivitis.
Study Selection:
Studies related to ocular allergy and/or allergic conjunctivitis were selected for inclusion in this review.
Results:
Four clinical scenarios are presented that mimic frequently encountered inflammatory disorders that present as red eyes.
Conclusions:
The signs and symptoms associated with the various inflammatory conditions affecting the conjunctiva often overlap and need to be differentiated to maximize care for patients with conjunctivitis.
