Anderson, Department of Ophthalmology, University of Utah, 50 North Medical Drive, Salt Lake City, UT 84132.] An 11-month-old girl with a rapidly expanding orbital mass as seen on computed tomography and magnetic resonance scanning (pictures included in the article) and then removal of what proved to be a probable aneurysmal bone cyst. This entity is briefly discussed. Lyn A. Sedwick, M.D. Long-term Effectiveness of Optic Nerve Sheath Decompression for Pseudotumor Cerebri. Spoor TC, McHenry JG. Arch Ophthalmol 1993;111:632-5 (May). [Reprint requests to Dr. T. C. Spoor, Kresge Eye Institute of Wayne State University, 4717 St. Antoine, Detroit, MI48201.] Drs. Spoor and McHenry review records on 54 patients (75 eyes) undergoing optic nerve sheath decompression for pseudotumor cerebri. Of these 54, 32% experienced deterioration after an originally successful operation. It is unclear whether measurement of intracranial pressure was done routinely to assess optic nerve sheath decompression failure, although the authors note "failure and visual deterioration can occur anytime after optic nerve sheath decompression and may not be accompanied by optic disc swelling or decreased visual acuity, even in the presence of markedly elevated intracranial pressure." They recommend, based on these results, that patients with pseudotumor cerebri and optic nerve sheath decompression undergo "compulsive, lifelong follow-up with routine visual field testing." They postulate that visual loss may occur by scarring, vascular occlusion, or postoperative inflammation and necrosis of the optic nerve. Lyn A.

[Reprint requests to Dr. K. Ohara, 3311-1 Yakushiji, Minamikawachi- machi, Kawachi-gun, Tochigi-ken, Japan 32904.] Sixty patients with suspected ocular sarcoid and minimal systemic evidence for same had transbronchial lung biopsy with positive results in 37 (61.7%). Only one complication (transient small pneumothorax) was encountered, and the authors recommend this technique for patients in whom noninvasive testing, such as angiotensinconverting enzyme or gallium scan, is suggestive of sarcoid.

[Reprint requests to Dr. J. S. Glaser, 900 N.W. 14th Street, Miami, FL 33136.] Fluorescein angiography was done in 35 patients with acute anterior ischemic optic neuropathy, 19 of which were nonarteritic and 16 with biopsyproven giant-cell arteritis. In these arteritic patients, there was delayed fluorescein dye appearance and choroidal filling times. These findings are nicely presented in Table 1, which shows a signifi~ ant difference between nonarteritic ischemic optic neuropathy and arteritic ischemic optic neuropathy eyes in these and other fluorescein angiographic parameters. These differences were also |
