Anterior diffuse scleritis diagnosed as conjunctivitis

摘要: This article presents a case of anterior diffuse scleritis that initially was diagnosed as conjunctivitis. Anterior diffuse scleritis (ADS) is a potentially vision-threatening inflammation of the sclera whose etiology may include autoimmune and systemic conditions such as rheumatoid arthritis and tuberculosis. The signs and symptoms of ADS include pain, tearing, tenderness, redness, painful sensitivity to light and decreased visual acuity. Ocular and physical examinations including blood tests to rule out underlying causes are important. Medications such as corticosteroids, non-steroidal anti-inflam-matory drugs and possibly immune-suppressants are used in the management of ADS. If care is not taken, ADS can be mis-diagnosed as conjunctivitis because the redness is similar in both conditions. Such mis-diagnosis can be sight-threatening and therefore it is essential that primary eye care practitioners are cautious in all diagnoses of red eye conditions. (S Afr Optom 2012 71(1) 51-54)
