The authors discuss the literature regarding intracranial gliomas arising after irradiation of pituitary adenoma. Lyn A. Sedwick, M. D. Recurrent Blepharoptosis Secondary to a Pituitary Tumor. Small KW, Buckley EG. Am J Ophthalmol 1988; 106: 760- 1 ( Dec). [ Inquiries to Dr. E. G. Buckley, P. O. Box 3802, Department of Ophthalmology, Duke University Medical Center, Durham, NC 27710.] An ll- year- old girl had ptosis without ocular motility or pupil abnormalities that promptly resolved following resection of a pituitary adenoma with suprasellar extension, but without cavernous sinus extension. The authors discuss possible mechanism for what they feel represents a partial third nerve palsy. Lyn A. Sedwick, M. D. Successful Treatment of Postherpetic Neuralgia with Capsaicin. Bucci FA Jr, Gabriels CF, Krohel GB. Am J Ophthalmol 1988; 106: 758- 9 ( Dec). [ Inquiries to Dr. G. B. Krohel, Samaritan Hospital, Troy, NY 12180.] Two patients with chronic postherpetic neuralgia were treated with topical capsaicin ( Zostrix) with excellent relief of pain. Lyn A. Sedwick, M. D. Ocular Ischemic Syndrome Secondary to Carotid Artery Dissection. Duker JS, Belmont JB. Am J Ophthalmol 1988; 106: 750- 2 ( Dec). [ Inquiries to Dr. ]. B. Belmont, Retina Service, Wills Eye Hospital, Ninth and Walnut Sts., Philadelphia, PA 19107.] A 64- year- old man with a complaint of amaurosis fugax was found to have iris neovascularity and retinal hemorrhages consistent with ocular ischemic syndrome. Arteriography demonstrated a carotid artery dissection and the patient did well J Clin Neuro- ophthalmol, Vol. 9, No. 3, 1989 with medical treatment and pametinal photocoagulation. Lyn A. Sedwick, M. D. Correlation of Afferent Pupillary Defect with Visual Field Loss on Automated Perimetry. Johnson LN, Hill RA, Bartholomew MJ. Ophthalmology 1988; 95: 1649- 55 ( Dec). [ Reprint requests to Dr. L. N. Johnson, Neuro- Ophthalmology Unit, The Milton S. Hershey Medical Center, The Pennsylvania State University, Hershey, PA 17033.] The authors compared the strength of an afferent pupillary defect to differences between the 30° visual fields of each eye. They found a fairly linear relationship between log afferent pupillary defect and visual field differences on Humphrey automated perimetry ( Program 30- 1). Four patients with a weak afferent pupillary defect were found to have normal 30° visual field testing, indicating the exquisitely sensitive nature of the pupil response. One conclusion that the authors made was that interocular difference of > 8.7 dB on 30° visual field testing without an afferent pupillary defect was indicative of a functional visual field loss with 95% confidence limit. Lyn A. Sedwick, M. D. Bumpy Muscles. Slamovits TL, Burde RM, with comments by Sedwick L, Newman S, Katz B. Surv OphthalmoI1988; 33: 189- 98 ( Nov- Dec). [ No reprints available. ] You should read this article not because yours truly wrote some of the comments, but rather because the case discussed is so unusual- an otherwise healthy 63- year- old man who developed a restrictive ocular myopathy and " bumpy"- looking extraocular muscles on computerized tomographiC scanning. The diagnostic possibilities seem endless, and the waterfront is more than adequately covered by the discussants, but the answer was metastases to extraocular muscles biopsied by fineneedle aspiration.
