Show 76 LITERATURE ABSTRACTS Spontaneous Improvement of Progressive Anterior Ischemic Optic Neuropathy: Report of Two Cases. Aiello AL, Sadun AA, Feldon SE. Arch Ophthaimol 1992;110:1197-9 (Sept). [Reprint requests to Dr. S. E. Feldon, Doheny Eye Institute, 1450 San Pablo St, Los Angeles, CA 90033.] The authors report two patients with progressive anterior ischemic optic neuropathy who did not undergo optic nerve sheath decompression and over follow-up had quite good return of central acuity, although visual field defects persisted. As they note, we may not know the natural history of this disease process as well as we think we do in order to evaluate the efficacy of optic nerve sheath decompression in its management. Lyn A. Sedwick, M.D. Microanatomy of the Orbital Apex. Computed Tomography and Microcryoplaning of Soft and Hard Tissue. Goldberg RA, Hannani 0, Toga AW. Ophthalmology 1992;99:1447-52 (Sept). [Reprint requests to Dr. R. A. Goldberg, 100 Stein Plaza, Los Angeles, CA 90024-7006.] The authors present their adaption of "microcryoplaning and computer reconstruction ... in viewing the detailed anatomy of the orbital apex." The microplaning was done with autopsy sections on four heads and compared to computed tomography pictures. They hope their work will ultimately supply information about many normal variants to orbital anatomy, in part to aid in surgery of this region. Lyn A. Sedwick, M.D. Color Doppler Imaging of the Ocular Ischemic Syndrome. Ho AC, Lieb WE, Flaharty PM, Sergott RC, Brown GC, Bosley TM, Savino PJ. Ophthalmology 1992;99:145~1 (Sept). [Reprint requests to Dr. R. C. Sergott, Wills Eye Hospital, Ninth and Walnut Sts, Philadelphia, PA 19107.] The authors used this interesting technique to study 21 patients with ocular ischemic syndrome. All patients had high-grade carotid stenosis. Color I Clill Nruro-ophthalmol. Vol. 13. No. 1. 1993 Doppler demonstrated reduced central retinal artery peak systolic blood flow velocity and reversal of ophthalmic artery flow in 12 of 16 eyes with ocular ischemic syndrome. They also found posterior ciliary artery peak systolic flow velocity to significantly correlate with visual acuity. Lyn A. Sedwick, M.D. Effects of Eyelid Protractor Excision for the Treatment of Benign Essential Blepharospasm. Frueh BR, Musch DC, Bersani TA. Am JOphthalmol1992; 113:681-6 Oune). [Reprint requests to Dr. B. R. Frueh, W. K. Kellogg Eye Center, 1000 Wall St., Ann Arbor, MI48105-1994.] Thirty-seven consecutive patients who had upper eyelid protractor excision for treatment of blepharospasm were studied retrospectively in this study. Some (14) had previous botulism injections. After one surgery, 40.5% had acceptable relief of symptoms; excluding patients who declined further surgery, 81.5% ultimately had satisfactory relief with one or more surgery. The authors believe this type of surgery had results comparable to differential section of the facial nerve and fewer unacceptable complications. Lyn A. Sedwick, M.D. Lyme Disease? and reply. Winterkorn JMS, Lightman DA, Brod RD, Gordon G. Arch Ophthalmol 1992;110:749-50 (June). [No reprint information given.] An interesting volley of letter to the editor and reply from the authors regarding a recently reported case of Lyme disease and retinal artery occlusion. Dr. Winterkorn believes that the patient reported probably had syphilis and that the retinal artery occlusion was incidental. Drs. Lightman, Brod, and Gordon believe that the lab evidence supports Lyme disease and clinical suspicion is high that the retinal artery occlusion was related, given the other ophthalmic findings.
