Optic Nerve Sarcoidosis

Optic nerve sarcoidosis: MR findings.

Neurologic involvement has been described in 5% of patients with sarcoidosis; however, direct granulomatous involvement limited to the optic nerve but not involving the chiasm is rare. We describe two patients with biopsy-proven sarcoidosis; the fat-suppressed gadolinium-enhanced MR findings showed sarcoid involvement limited to the optic nerves.

Optic neuropathy in sarcoidosis.

Five patients with isolated optic neuropathy and sarcoidosis are discussed. The spectrum of clinical disease was variable but two groups could be identified: patients with chronic progressive visual loss which was associated with thickening of the optic nerve and was refractory to steroid treatment, and patients with acute or subacute optic neuropathy in which the visual loss responded rapidly ...

Effect of scuba-diving on optic nerve and sheath diameters

  Background :There is not any data available about the effect of high bar pressure condition on intracranial pressure. In this study, the effect of diving on the optic nerve and sheath diameters as non-invasive markers of intracranial pressure has been investigated.   Methods : Twenty professional male divers from twenty one volunteers were chosen for this cross-sectional study. Only one perso...
