Ophthalmology 1993;100:306-11 (Mar). [Reprints requests to Dr. T. C. Spoor, Kresge Eye Institute, 4717 St. Antoine, Detroit, M148201.] Twenty-two patients with nonarteritic ischemic optic neuropathy and progressive visual loss over 1 to 70 days (most less than 30 days) were compared to 15 patients with nonarteritic ischemic optic neuropathy without progression in regard to resulting visual function after optic nerve sheath decompression. The former group had improvement in visual acuity but not field, but the latter group had no improvement in either acuity or field. Sonographic data is also included, which suggests that intrasheath fluid accumulation may be a predictive factor in progressive ischemic optic neuropathy. Lyn A. Sedwick, M.D. Peripapillary Hemorrhage. Winterkorn JMS. Comments. Breen L, Rizzo J. Addendum. Winterkorn JMS, Lin HZ. Surv OphthalmoI1993;37:36272 (Mar-Apr). [Reprint address: Dr. J. M. S. Winterkorn, Department of Ophthalmology, 300 Community Drive, Manhasset, NY 11030.] A 61-year-old gentleman with presumably incidental finding of peripapillary hemorrhage on ophthalmic examination had neuro-ophthalmic evaluation in which a slightly slow abducting saccade in the left eye was noted as well as incomitant esodeviation in left gaze to Maddox rod testing. He also demonstrated a subtle right field defect to confrontation with a red stimulus. The discussants have an understandably difficult job reconciling these neuro-ophthalmic findings with one unifying diagnosis. The patient turned out to have a right frontal cortex neoplasm. A number of thoughtful comments were made about this case from all of the discussants as well as the author. Lyn A. Sedwick, M.D. Systemic Viral Infections and Their Retinal and Choroidal Manifestations. Yoser SL, Forster OJ, Rao NA. Surv Ophthalmol 1993;37:313-52 (Mar- JClm Neuro-ophthalmol, Vol. 13, No.3, 1993 Apr). [Reprint address: Dr. N. A. Rao, 1355 San Pablo Street, Los Anegeles, CA 90033.] Although this article's major focus is on retinal and choroidal complications of viral infections, there is discussion of optic neuropathies including optic neuritis and papillitis. Other neuroophthalmic complications of viral infections are also at least mentioned, particularly in regard to herpes zoster. This is a nice current reference on posterior pole complications of common and uncommon viral infections. Lyn A. Sedwick, M.D. HLA-A29 as a Potential Risk Factor for Nonarteritic Anterior Ischemic Optic Neuropathy. Johnson LN, Kuo HC, Arnold AC. Am JOphthalmol 1993;115:540-2 (Apr). [Inquiries to Dr. L. N. Johnson, Neuro-Ophthalmology Division, Mason Institute of Ophthalmology, University of Missouri- Columbia, Columbia, MO 65212.] Twenty-one patients with nonarteritic anterior ischemic optic neuropathy had HLA analysis done, and their results were compared to 1,029 controls from North American white patients. A significant correlation with anterior ischemic optic neuropathy was found for HLA-A29 only. How HLA-A29 may exert an effect in the development of the anterior ischemic optic neuropathy is unknown. Lyn A. Sedwick, M.D. Metastatic Renal Cell Carcinoma Manifesting as an Orbital Mass. Wolin MJ. Am JOphthalmol1993; 115:542-3 (Apr). [Inquiries to Dr. M. J. Wolin, Four Richland Medical Park, Suite 300, Columbia, SC 29203.] A 66-year-old man presented with an orbital mass which proved to be clear-cell carcinoma with biopsy. A primary renal-cell carcinoma was subsequently found involving the left kidney. This type of primary presentation in the orbit has been previously described, albeit rarely, according to the authors.
