Ophthalmology 1988; 95: 1554- 8 ( Nov), [ Reprint requests to Dr. C. R. Leone Jr., Medical Center Tower 1, # 505, 7950 Floyd Curl Dr., San Antonio, IX 78229.] A 10- year- old boy with subacute proptosis was found to have an osteoblastoma of the orbit. This tumor, unusual in the orbits, was studied preoperatively with computerized tomographic and magnetic resonance scanning.

[ Reprint requests to Dr. R. C. Kersten, University of Cincinnati Hospital, Christian R. Holmes Division, Eden and Bethesda Aves., Mail Location 418, Cincinnati, OH 45267.] Two cases with computerized tomographic and magnetic resonance scans are presented. The authors feel that magnetic resonance can be used to establish a firm diagnosis preoperatively in these lesions, which can mimic malignancy because of associated erosion and/ or expansion of nearby orbital bones.

[ Reprint requests to Dr. J. P. Lee, Moorfields Eye Hospital, London, WC1V7AN, England.] Be prepared to sit down with this article for a while, pen in hand, to interpret the results. Unfortunately, informatinn that should be in tables is not always there, e. g., groups II AI> and " B," which 214 © 1989 Raven Press, Ltd., New York include patients who had previous medial rectus surgery and those who had not, are distinguished in the text only, and you must identify them yourself in the summary tables presented. We are told that overall, 63% of patients were brought to fusion with the procedures described, but one wonders where and how, as more than half of the patients were slated for further surgery. The use of botulinum A may be useful in selected patients with sixth nerve palsy, especially because it obviates the risk of anterior segment ischemia from medial rectus recession done in conjunction with lateral, superior, and inferior rectus surgery, but this article is not a convincing testimonial.

[ Reprint requests to Dr. J. J. Dutton, Duke University Eye Center, Box 3802, Durham, NC 27710.] Two hundred thirty- two patients with a total of 1,044 treatments over 4 years form this study. Some complication occurred in 22.6% of treatments but usually was local and transient, e. g., dry eye. Ptosis occurred in 7.3% of treatments and diplopia in 1%. Previous eyelid surgery did not predispose to complications. Lyn A. Sedwick, M. D. Orbital Myositis Involving the Oblique Muscles: An Echographic Study. Wan WL, Cano MR, Green RL.
