Coli GE, Derner JL Am JOphthalmol1992;114:489-93 (Oct). [Reprint requests to Dr. J. L Derner, Jules Stein Eye Institute, UCLA, 100 Stein Plaza, Los Angeles, CA 90024-7002, ] The authors report their experience using the Hess screen on patients with myasthenia gravis during a Tensilon test. They defined a positive test as a 50% or greater reduction in the initial strabismic deviation within 1 minute of Tensilon infusion. They tested 10 normals, 12 nonmyasthenic patients with acquired strabismus, and 10 patients with strabismus from ocular myasthenia gravis. None of the nonmyasthenic or control patients had a positive test, and all myasthenic patients had 50% or greater reduction in their deviation. They feel that the Hess screen used with Tensilon is a sensitive and specific test for the diagnosis of strabismus caused by myasthenia gravis. Lyn A. Sedwick, M.D. Idiopathic Alternating Anisocoria. Brodsky MC, Sharp GB, Fritz KJ, Corbett JJ. Am J Ophthalmol 1992;114:509-10 (Oct). [Inquiries to Dr. M. C. Brodsky, Arkansas Children's Hospital, 800 Marshall, Little Rock, AR 72202.] A 15-year-old boy is described who has a 2-week history of alternating anisocoria with the pupils reversing in size 2 to 4 times daily. His workup included a full neurologic examination and magnetic resonance scanning of the head, both of which were normal. It is unclear what caused this young man's alternating anisocoria. Lyn A. Sedwick, M.D. Neuro-ophthalmic Associations and Complications of Diabetes Mellitus. Burde RM, Am JOphthaimol 1992;114:498-501 (Oct). [Reprint requests to Dr. R. M, Burde, Department of Ophthalmology, 148 © 1993 Raven Press, Ltd., New York Albert Einstein College of Medicine and Montefiore Medical Center, 111 E. 210 St., Bronx, NY 10467,] Dr. Burde gives a nice "clinical capsule" of neuro-ophthalmic problems related to diabetes. Entities such as optic disc hypoplasia in children of diabetic mothers, diabetic cranial mononeuropathy involving ocular motor nerves, diabetic papillopathy, and zygomycosis are discussed among others. A very nice list of references is included in this succinct "perspective" article, Lyn A. Sedwick, M.D. 'V' Esotropia and Excyclotropia After Surgery for Bilateral Fourth Nerve Palsy. Kushner BJ. Arch OphtJwlmol 1992;110:1419-22 (Oct). [Reprint requests to Dr. B. J. Kushner, University Station Clinics, 2880 University Ave., Room 336, Madison, WI 53705-3631.] The author reports his experience with 6 patients who had a "v" esotropia and excyclotropia after surgery for bilateral superior oblique palsy. These patients were successfully treated with recession of the inferior recti muscles bilaterally. Lyn A. Sedwick, M.D. IV Steroids for Central Retinal Artery Occlusion in Giant-Cell Arteritis.
