LOW-DOSE CYCLOSPORINE THERAPY OF GRANULOMATOUS OPTIC NEUROPATHY AND ORBITOPATHY

Four patients with granulomatous disease of the anterior visual pathway presented with optic neuropathy between July 1986 and February 1987, secondary to an orbital pseudotumor (n = 1) and sarcoidosis (n = 3). All but one became resistant to corticosteroid therapy, and all were subsequently treated for 1 to 2 years with low-dose cyclosporine alone or in combination with tapering doses of prednisone. Two patients experienced pronounced recovery of visual function, and visual function was stabilized in the other two; in one of these, magnetic resonance imaging showed substantial regression of intracranial lesions. Steroid-induced complications of uncontrolled hyperglycemia (n = 2) and obesity (n = 4) were controlled with cyclosporine. The authors conclude that low-dose cyclosporine is a safe and effective therapeutic alternative in ocular granulomatous diseases.
