[ Reprint requests to Dr. A. Spierer, Goldschleger Eye Institute, Sheba Medical Center, Tel Hashomer 52621, Israel.] The authors investigated the degree of increase in intraocular pressure in upgaze in normal controls and in patients with thyroid eye disease. Only those with presumed infiltrative disease had a significant increase in intraocular pressure that was greater than controls, and the overlap of all groups brings into question the validity of this test as an indicator of Graves' disease. Lyn A. Sedwick, M. D. Graves' Exophthalmos Unrelated to Extraocular Muscle Enlargement. Superior Rectus Muscle Inflammation May Induce Venous Obstruction. Hudson HL, Levin L, Feldon S. Ophthalmology 1991; 98: 1495- 99 ( Oct). [ Reprint requests to Dr. S. E. Feldon, Doheny Eye Institute, 1355 San Pablo Street, Los Angeles, CA 90033.] The authors postulate that exophthalmos of Graves' disease can be secondary to isolated superior rectus enlargement with secondary superior ophthalmic vein enlargement and subsequent orbital congestion. They present a representative computed tomographic scan. This is an interesting paper. Lyn A. Sedwick, M. D. Inferior Rectus Muscle Contracture Syndrome After Local Anesthesia. Hamed LM, Mancuso A. Ophthalmology 1991; 98: 1506- 12 ( Oct). [ Reprint requests to Dr. L. M. Hamed, Department of Ophthalmology, J. Hillis Miller Health Center, Box J- 284, Gainesville, FL 32610- 0284.] Eight consecutive patients with ipsilateral hypotropia following cataract surgery with local anesthesia are presented. Computed tomographic scanning showed an enlarged inferior rectus muscle, which the authors postulate represents fibrosis. The four patients who had strabismus surgery did well. Lyn A. Sedwick, M. D. J Clin NeuTo- ophthafmol, Vol. 12, No. 2, 1992 Treatment of Unilateral Acute Sixth- nerve Palsy With Botulinum Toxin. Metz HS, Dickey CF. Am J OphthalmoI1991; 112: 381- 4 ( Oct). [ Reprint requests to Dr. H. S. Metz, Department of Ophthalmology, University of Rochester Medical Center, 601 Elmwood Avenue, Box 659, Rochester, NY 14642.] The authors review a series of 29 patients who had acute sixth nerve palsy from a variety of causes, which they treated with botulinum injection into the ipsilateral medial rectus muscle. They, like others, found this to be a good technique for restoring single binocular vision, but note that a prospective study would be desirable. Lyn A. Sedwick, M. D. Asymmetric Pigmentary Dispersion Syndrome Mimicking Horner's Syndrome. Haynes WL, Thompson HS, Kardon RH, Alward WLM. Am J Ophthalmol 1991; 112: 463- 4 ( Oct). [ Inquiries to Dr. W. L. M. Alward, O'Brien Library, Department of Ophthalmology, University of Iowa Hospitals and Clinics, Iowa City, IA 52242.] A patient with pigmentary dispersion syndrome with elevated intraocular pressures was found to have anisocoria suggestive of Homer's syndrome, which pupillometric studies did not confirm. The eye with the larger pupil showed more pigment dispersion and had a darker iris. The authors cite other cases of anisocoria with pigmentary dispersion syndrome and note that heterochromia may result from greater lens- iris contact in the eyes with the larger pupil. Lyn A. Sedwick, M. D. Blind Spot Enlargement as a Manifestation of MuItifocal Choroiditis. Khorram KD, Jampol LM, Rosenberg MA. Arch Ophthalmol 1991; 109: 1403- 7 ( Oct). [ Reprint requests to Dr. L. M. Jampol, Department of Ophthalmology, Northwestern University School of Medicine, 303 E. Chicago Avenue, Chicago, IL 60611.] Several patients with multifocal choroiditis were found to have normal- appearing optic nerve heads, but enlarged blind spots on visual field examination. The authors compare and contrast their patients to those with acute idiopathic big blind |
