Basti-aensen LAK, [ Correspondence and reprint requests to L. A. K. Bastiaensen, Nieuwe Bosscheweg 17, 5017 JJ Til-burg, The Netherlands]. The hallmark of supraorbital neuralgia is localized pain in or above the eyebrow ( sometimes extending into the parietotemporal scalp region). The pain is intermittent; however, longer periods with different severity occur. It can be triggered by pressure on the supraorbital notch. In this study, 84% of the 50 patients were women with an average age of onset in the forties or fifties. The proposed treatment is an injection of 2 mL of 2% lidocaine and 1: 60,000 adrenalin in the supraorbital channel. In 84% of patients, the pain was abolished or substantially alleviated. The average postinjection time is 14 months. Complications reported are local hemorrhage, transient diplopia, and transient anesthesia of the supraocular skin, mostly lasting only days. Radiation Optic Neuropathy: Report of Cases, Role of Hyperbaric Oxygen Therapy, and Literature Review. [ FX Borruat, Schatz NJ, Glaser JS, Matos L, Feuer W. Correspondence and reprint requests to Dr. F. - X. Borruat, Hopital Ophtlamique Jules, Gonin, University Eye Clinic, Avenue de France 15, 1004 Lausanne, Switzerland.] Radiation- induced optic neuropathy ( RON) with subsequent neural necrosis is a dilemma for both patients and their doctors. It may occur even with dosages well within the therapeutic range. Most patients manifest 8 to 13 months after treatment. Hyperbaric oxygen ( HBO) therapy has been used for more than 30 years. The outcome varies considerably. This article reports five patients with RON. Four were treated with HBO and one was not. In summarizing outcomes, the one patient in this study who was not treated with HBO remained unchanged. Of the HBO- treated patients, one deteriorated despite HBO therapy, two patients improved ( one of them dramatically), and one patient remained unchanged. One problem of this report is that these patients were not treated with HBO alone but also with intravenous steroids. This makes it difficult to attribute the improvement to the HBO treatment alone. My personal experience with HBO treatment is limited to one patient who was receiving anticoagulation therapy during the time of radiation therapy and later went blind in both eyes, despite HBO therapy ( Neurology 1196: 46: 889). Centripetal Nystagmus in a Case of Creutzfeldt- Jakob Disease. Helmchen C, Biittner U. Neuro-ophthalmology 1995,15: 187- 92. [ Correspondence and reprint requests to Dr. Christoph Helmcken, Department of Neurology, Klinikum Grosshadern, University of Munich, Marichoninistr. 15, D- 81377 Munich, Germany.] Creutzfeldt- Jakob disease ( CJD) has gained a lot of publicity because of its possible connection to bovine spongioform encephalopathy. The diagnosis of this fatal disease is made on clinical grounds and on findings from electroencephalography and, finally, biopsy. The authors describe the case of a 63- year- old man who was admitted to the hospital because of rapidly progressing unsteadiness. In addition to the clinical examination of eye movements, binocular horizontal and vertical electrooculogra-phy was performed. An acquired form of bilateral horizontal and vertical centripetal nystagmus and rebound nystagmus was diagnosed. This rare type of nystagmus is most likely a sign of cerebellar disease and has not yet been reported in CJD. Fiillung Optikoziliarer Shuntgefasse Bei Stauungs-papille: Ein Indikator fur den Druck in der Sehner-venscheide. Wolf- Dietrich A. Lagreze WA, Kommerell G. Klinisches Monatsblatt Augenheilkunde 1996, 209: 252- 5. [ Correspondence and reprint requests to Dr. Wolf- Dietrich A. Lagreze, Universitiits- Augenklinik, Killianstrasse 5, D- 79106 Freiburg, Germany.] Opticociliary vessels are a rare finding in longstanding papilledema. Optic nerve sheath fenestration ( ONSF) was performed in a patient who had severe loss of visual acuity and loss of visual field from pseudotumor cerebri. B- scan examination revealed a massively enlarged optic nerve sheath, and opticociliary vessels were present on fundus examination. After ONSF, the diameter of the optic nerve sheath decreased and the opticociliary vessels collapsed. Two weeks after the procedure, the shunt vessels were filled again. The authors therefore conclude that the diameter of opticociliary shunt vessels may be an indicator of the pressure within the subarachnoidal space of the optic nerve. 221 [VBcreutzfeldjacob] |
