Treatment of Idiopathic Inflammatory Orbital Syndrome (IOIS) With Prominent Lacrimal Gland Involvement Using Oral Non-Steroidal Anti-Inflammatory Drugs (NSAIDs).

Idiopathic orbital inflammatory syndrome (IOIS) is a chronic inflammatory process of unknown etiology, which can either be localized or diffuse. In cases where there is isolated inflammation of the lacrimal gland, it is known as dacryoadenitis. This study focuses on the treatment of a patient with IOIS with prominent lacrimal gland involvement. The mainstay of treatment for idiopathic isolated dacryoadenitis is oral corticosteroids, but non-steroidal anti-inflammatory drug (NSAIDs) is known to be effective in treating idiopathic dacryoadenitis as well. There is no formal study yet to evaluate the use of NSAIDs in treating idiopathic dacryoadenitis. Here, we report a case of idiopathic isolated dacryoadenitis which was successfully treated with NSAIDs.
