[The diagnostic investigations should be efficient for patients with uveitis].

Uveitis is a common and etiologically complex disease. The diagnosis of uveitis is mainly based on clinical findings, and no ancillary test is needed for diagnosis of the most common uveitis entities in China. Ancillary tests, however, are needed to identify the underlying cause when the clinical presentation points to some specific disease entity, and when infectious uveitis or masquerade syndrome is suspected. A variety of ophthalmic imaging techniques and laboratory tests analyzing blood or intraocular fluid are currently available for etiological identification in uveitis as well as for disease follow-up. When these tests are considered, the less invasive, expensive and time-consuming ones should be chosen.
