Show 128 LITERATURE ABSTRACTS of the differential diagnoses. Possible causes of disc edema and forms of pseudotumor cerebri are well discussed and succinctly summarized in table form. Lyn A. Sedwick, M. D. Neuroretinitis Associated With Cat Scratch Disease. Bar S, Segal M, Shapira R, Savir H. Am J Ophtha/ mol 1990; 110: 703- 5 ( Dec). [ Inquiries to Dr. H. Savir, Department of Ophthalmology, Hasharon Hospital, P. O. Box 121, Petah- Tiqva 49372, Israel. ] A lO- year- old boy developed a neuroretinitis left eye. Approximately 3 weeks previously he had had a febrile disease with lymph node enlargement that had been preceded by a cat scratch. Lyn A. Sedwick, M. D. Ocular Movements in Essential Blepharospasm. Derner JL, Holds JB, Hovis LA. Am J Ophthalmol 1990; 110: 674- 82 ( Dec). [ Reprint requests to Dr. ]. L. Derner, Comprehensive Division, Doris Stein Research Center, 100 Stein Plaza, UCLA, Los Angeles, CA 90024- 7002.] Eight patients with blepharospasm and seven control patients had electrooculographic examination which determined whether the brain stem lesion which may cause blepharospasm involves ocular motor pathways. No differences between subjects and controls were found; this " suggests that the lesion in blepharospasm is specificially limited to neurons regulating the facial muscles." Lyn A. Sedwick, M. D.

Garrity, Department of Ophthalmology, Mayo Clinic, 200 First Street SW, Rochester, MN 55905.] Thirteen patients, seen between 1982 and 1989, are presented who had initial complaints of head-felin NeurlH1pht1llJlnwl, Vol. :/' 1, No. 2, 1991 aches or visual symptoms and demonstrated patulous optic nerve sheaths ( i. e., optic nerves seen inside enlarged nerve sheaths) on computerized tomographic or magnetic resonance scans. The findings are tabulated for easy review in one table, but they are also discussed in the text as case reports in four patients. One of the two patients who had lumbar puncture had an elevated cerebrospinal fluid pressure. Several patients had visual loss; one patient had neurofibromatosis. The authors wish to recognize these patients, who have somewhat disparate clinical histories and examination, as a single entity based on radiologic findings that they call meningocele of the optic nerve. They review findings and tabulate data from other similar reported cases. A very interesting article. Lyn A. Sedwick, M. D. Vision Despite Tomographic Absence of the Occipital Cortex. Summers CG, MacDonald JT. Surv Ophthalmo/ 1990; 35: 188- 90 ( Nov- Dec). [ Reprint requests to Dr. C. G. Summers, Department of Ophthalmology, University of Minnesota, Box 493 UMHC, 516 Delaware Street SE, Minneapolis, MN 55455.) A 14- month- old boy was evaluated for developmental delay and esotropia. He was microcephalic from birth and computerized tomographic scanning showed no occipital cortex, as part of severe absence of cortical parenchyma. At 2 years of age he had reduced " corrected binocular grating acuity" but central, steady, and macular fixation both eyes and no nystagmus. The authors speculate that the child's vision results from " heterotopic occipital cortex" and caution that vision function cannot be predicted when a malformation like this is seen on a congenital basis.
