A patient with an initially undiagnosed copper containing intraocular foreign body developed chalcosis 4 1/2 years after penetrating injury. The case was followed for approximately 15 years after which time the foreign body expelled itself with complete reversal of the ocular signs and improvement in visual acuity.
A two- to three-fold elevation in serum creatine kinase levels were found in patients postoperatively after scleral buckling procedures. Further fractionation revealed the myocardial band (CK-MB) to be absent; with skeletal muscle (CK-MM) contributing to the enzyme elevation. Isoenzymes are recommended in postoperative patients when myocardial infarction is considered.
Neovascular fundus abnormalities are an unusual complication of peripheral uveitis. Peripheral retinal neovascularization was seen in 11 patients, six of whom had retinal angioma-like lesions. Most of the patients had loss of vision caused by vitreous hemorrhage. In four additional patients with peripheral uveitis, neovascularization developed either at the disc or elsewhere in the posterior pole.
