Diagnostic Considerations

The examiner must be cognizant of conditions that masquerade as scleritis, such as toxoplasmosis-induced posterior uveitis and chronic lymphocytic leukemia. [23, 24]  Episcleritis often presents similarly to scleritis, but inflammation and erythema is isolated to the episclera, which lies between the sclera and the conjunctiva. [21]  Episcleritis has a more benign course and does not cause any visual changes or permanent impairment; however, recurrence is common.
