Show 150 LITERATURE ABSTRACTS eye, but elevation of the left optic disc. Computed tomography and magnetic resonance scans of the head were unremarkable. Lumbar puncture did reveal elevated cerebral spinal fluid pressure but also an abnormal protein. Approximately a year later, because of lower extremity difficulties, investigation led to diagnosis of a spinal cord tumor (malignant ependymoma). The authors discuss this very interesting presentation of visual loss and disc edema in a patient with a spinal cord tumor. Lyn A.

Ophthalmology 1992;99:1678-85 (Nov). [Correspondence to Dr. J. D. M. Gass, Bascom Palmer Eye Institute, P.O. Box 016880, Miami, FL 33101.] Seven patients who presented with or developed chorioretinal scars or neovascularization such as that seen with multifocal choroiditis or pseudo-presumed ocular histoplasmosis syndrome are discussed. All seven had photopsia and blind spot enlargement during their illness, and four had multiple evanescent white dot syndrome. The authors believe this to be yet another clinical disorder related to, or a subset of, acute idiopathic blind spot enlargement syndrome and multiple evanescant white dot syndrome. Lyn A.

[Letters to the editor and reply, no reprint information.] A very interesting volley of letter to editor and reply regarding a previously published report, which alleged that optic nerve decompression reverses visual defects in pseudotumor cerebri even in cases with functioning lumboperitoneal shunts but progressive visual loss. Dr. Wall correctly notes that continuously normal shunt function was not proven by the authors and that intermittent shunt dysfunction was possible. The authors concede this point but note that these patients had "clinically" functioning shunts and rather than revise them, in the face of normal cerebral spinal I 011/ NClIrt1·ophthalmol.

Hoyt, Department of Neurological Surgery, % The Editorial Office, 1360 Ninth Ave, Suite 210, San Francisco, CA 94122.] The authors present 13 magnetic resonancestudied cases of optic nerve sheath meningioma and contrast the ability of magnetic resonance versus computed tomography to detect and define lesions. Clinical and magnetic resonance findings in 13 patients are summarized in a table and nice magnetic resonance pictures are included. Lyn A, Sedwick, M,D.

Kraft, Department of Ophthalmology, The Hospital for Sick Children, 555 University Ave, Toronto, Ontario, Canada M5G 1X8.] The authors elaborate on a new system they developed for scoring field of single binocular vision. Their target is a (+), which permits the patient to appreciate torsional as well as horizontal diplopia. Their system seems to give a more accurate representation of disabling ocular misalignment than does the standard system, Lyn A.
