Show LITERATURE ABSTRACTS 285 lege of Medicine, P. O. Box 100284, Gainesville, FL 32610- 0284. ] Two patients who underwent optic nerve sheath fenestration were studied with ultrasonography, and one was studied with magnetic resonance imaging. In both patients, all studies showed a cystlike structure near the fenestration site, which helps support the hypothesis that this surgery works by allowing cerebrospinal fluid to percolate into the orbit.

Terwilliger Boulevard, Portland, OR 97201- 4197.] Two families are described with visual loss occurring in the second or third decade of life associated with optic atrophy and abnormal electroretinography. The authors believe their cases represent a distinct and new genetic disorder. Lyn A. Sedwick, M. D. Oral Therapy in Diffuse Unilateral Subacute Neuroretinitis. Gass JDM, Callanan DG, Bowman CB.

Chicago Avenue, Chicago, IL 60611.] A patient thought to have a slow- growing melanocytoma of the optic nerve head had enucleation after near- total visual loss occurred. Histologic diagnosis was malignant melanoma. Repeat surgery was required to extirpate the intracranial optic nerve, which contained tumor. Lyn A. Sedwick, M. D.

Glaser, Bascom Palmer Eye Institute, P. O. Box 016880, Miami, FL 33101.] The authors present six case reports of patients with pseudotumor cerebri secondary to dural sinus hypertension from a variety of causes. Nice standard angiograms, computerized tomographic, magnetic resonance, and magnetic resonance angiogram pictures, all of which helped to establish the proximate cause of the increased cerebrospinal fluid pressure, are included.
