E"en at this time interval far in excess of the several minutes required for human magnetic resonance exams, no ocular injury was detected b~' biomicroscopy or light microscopy in a two ~'ear post-exposure interval. The authors conclude that magnetic resonance is not likel\' to be hazardous to ocular tissues. LYI1 A. Sedwick, M.D. Complications of Fine Needle Aspiration Biopsy of the Orbit. Liu D. Oplltlwlmolo:.;y 1985;92(12): 1768-71 (Dec). [Reprint requests to Dr. Don Liu, Department of Ophthalmology, Henry Ford Hospital. 2799 W. Grand Blvd., Detroit, Ml 48202.] Dr. Liu surveyed 202 surgeons associated with the American Society of Ophthalmic Plastic and Reconstructive Surgery and other orbital surgeons in the U.s.A. and abroad. Responses came from 98 surgeons, 21 reporting experience with fine needle aspiration biopsy of the orbit. A total of 138 cases were seen primarily by orbital surgeons. Of these, 10 complications were noted; seven were of orbital hemorrhage, and none were severe (ptosis, motility problem, scar), These same surgeons saw in consultation 14 patients who had experienced complications following fine needle aspiration biopsy. Of these 14, three were blind and three died, Dr. Liu feels most serious complications Gin be avoided by meticulous adherence to accepted technique and with performance of the procedure by an experienced orbital surgeon. Dr. Kennerdell supplies discussion and agrees basically with Dr. Liu's conclusions. LYI1 A. Sedwick, M.D, The Use of Botulinum Toxin in the Medical Management of Benign Essential Blepharospasm. Perman KI, Baylis HI, Rosenbaum AI, Kirschen DG. Ophthalmology 1986;93:1-3 (jan). IReprint requests to K. I. Perman, M.D., 1145 19th St. NW, Washington, DC 20036.] Those who want yet further confirmation of the safety and efficacy of botulinum A toxin in the treatment of blepharospasm should read this article. Twenty-eight patients were treated, with good effect in 27. Eleven had one set of injections only (follow-up time was as long as 6 months in a few), but most patients required repeat injections on average every 3 months. Although all current articles on the use of botulism in the treatment of blepharospasm suffer from short follow-up time, there seems little doubt that such injections will be useful in the treatment of this distressing disease. LYI1 A. Sedwick, M.D. Contrast Sensitivity Testing in Pseudotumor Cerebri. Wall M. Oplztlll1lmolo:.;y 1986;93:4-7 (Jan). [Reprints, if available, from Dr. Wall. Department of Ophthalmology, Tulane University School of Medicine, 1415 Tulane Ave., New Orleans, LA 70112.) Dr. Wall tested patients with pseudotumor cerebri with Arden gratings and found decreased contrast sensitivity in 75'7c (9 of 12) of the patients, most of whom had normal Snellen acuit\'. There was some correlation between visual field abnormalities on Octopus computerized or Goldmann perimetry, but contrast sensitivity was abnormal with normal visual fields in some patients and vice versa. Seven of the 12 patients were seen more than once or twice, and these seven showed improvement in contrast sensitivity testing as papilledema resided. Arden plates seemed to be a good clinical test for following patients with pseudotumor cerebri, LYll A. Sedwick, M.D. I Clill Nl'IIn""I,',O",llIlol, Vol. 6. No.3, 1986 |
