Show LITERATURE ABSTRACTS 129 of the authors formed a cohort for this study. Of 188 patients, 56 had nystagmus which was usually fine, rapid, and horizontal. Of these 56, most had no clinically recognizable ocular pathology to account for the nystagmus. The authors postulate that it may be a pure motor nystagmus. Lyn A. Sedwick, M. D. Optic Nerve Head Swelling and Optic Atrophy in the Systemic Mucopolysaccharidoses. Collins MLZ, Traboulsi EI, Maumenee IH. Ophthalmology 1990; 97: 1445- 9 ( Nov). [ Reprint requests to Dr. E. I. Traboulsi, The Wilmer Eye Institute, Maumenee 321, 600 N. Wolfe Street, Baltimore, MD 21205.) This interesting paper reviews findings of 108 patients with mucopolysaccharidoses ( MPS) who were examined at The Johns Hopkins Center for Hereditary Eye Diseases between 1971 and 1988. Optic disc swelling was documented in a number of patients and in 4, optic atrophy followed the disc swelling. Work- up for raised intracranial pressure was usually unrevealing, although 1 patient did have hydrocephalus and was shunted. The authors discuss several possible mechanisms for the optic nerve appearance, including accumulation of acid mucopolysaccharides in the dura leading to a compressive optic neuropathy. Lyn A.

Mansour AM. Am J Ophthalmol 1990; 110: 706-- 7 ( Dec). [ Inquiries to Dr. A. M. Mansour, Department of Ophthalmology, University of Texas Medical Branch, Galveston, TX 77550.] These two articles document an orbital lymphoma in patients with acquired immunodeficien-cy syndrome ( AIDS). In the first article, this patient had been previously diagnosed with AIDS, but in the second article, the patient presented with proptosis and was subsequently diagnosed as having AIDS. Lyn A. Sedwick, M. D. Orbital Complications Secondary to Endoscopic Sinus Surgery. Neuhaus RW. Ophthalmology 1990; 97: 1512- 8 ( Nov). [ Reprint requests to Dr. R. W. Neuhaus, 3705 Medical Parkway, Suite 370, Austin, TX 78705.] Eight cases of " significant orbital complications" secondary to sinus surgery are presented, including three involving extraocular muscle function and two affecting the optic nerve. In his discussion, the author nicely walks the reader through a typical endoscopic procedure to clearly demonstrate when, where, and how orbital misadventures occur. Lyn A. Sedwick, M. D. Botulinum Treatment of Childhood Strabismus. Scott AB, Magoon EH, McNeer KW, Stager DR. Ophthalmology 1990; 97: 1434- 8 ( Nov). [ Reprint requests to Dr. A. B. Scott, Smith- Kettlewell Eye Research Institute, 2232 Webster Street, San Francisco, CA 94115.] Four hundred thirteen children with strabismus were treated with botulinum injection ( average 1.7 injections per patient). Follow- up for an average of 26 months was available on 362 patients, and overall, 61% had reduction of strabismus to within 10 prism diopters of orthophoria. Esotropes did better than exotropes and postsurgical consecutive esotropes had the best correction rate ( 93%). Lyn A. Sedwick, M. D.
