In a series of 281 patients with histologically confirmed sarcoidosis, 79 initially had ophthalmic sarcoid manifestations. Of 22 patients with uveitis, 21 were seen regularly as long as the inflammation was active, and 71 of the 79 patients (90%) underwent a follow-up study five to 16 years (mean, nine years) later and using the same protocol. ⋯ In 15 of these 33 patients, the general physical examination and the chest x-ray showed no evidence of systemic sarcoidosis. However, the serum angiotensin converting enzyme level was increased in a significantly greater proportion of these 15 patients than in the patients assessed as totally recovered from sarcoidosis.

Comparative Study
Magnetic resonance imaging of nonmetallic orbital foreign bodies.
We studied a cadaver head model in which we inserted three orbital foreign bodies. We chose these foreign bodies because of their similarity to substances found in orbital trauma. ⋯ While both orbital ultrasound and plain skull films failed to detect the foreign bodies consistently, both computed tomography and magnetic resonance imaging detected and localized the foreign bodies relatively well. Computed tomography was better in delineating shape and characterizing composition.
