Teruel, Department of Nephrology, Hospital Ramon y Cajal, C. Colmenar 9,1, 28034 Madrid, Spain.] This intriguing case report presents a 56- yearold man who lost vision 3 years earlier while on fluprednisolone therapy for bullous epidermolysis, but recovered vision when therapy was stopped. He then developed multiple myeloma with secondary amyloidosis that was again treated with corticosteroid ( prednisone) and melphalan; there was documented optic- nerve- type visual loss left eye that resolved upon discontinuation of the prednisone ( he continued to take melphalan). Although no scans or other evidence to discount the possibility of central nervous system m~ lti'ple myeloma was given, the authors feel that this IS a case of corticosteroid- induced toxic optic neuropathy.

Bielory, Immuno- ophthalmology Research Laboratory, UMDNew Jersey Medical School, 185 S. Orange Avenue, MSB £- 583, Newark, NJ 07103- 2714.] The authors treated one patient with orbital pseudotumor and three with sarcoidosis with lowdose cyclosporine, usually while tapering corticosteroids. All had become refractory to corticosteroids or had intolerable side effects. Some had been tried on other therapies ( radiation therapy, azathioprine, cyclophosphamide). Their experience with low- dose cyclosporine ( 2 mg/ kg/ day) was favorable in controlling disease with minimal side effects. Lyn A. Sedwick, M. D. Intradiploic Epidermoid Cysts of the Bony Orbit. Eijpe AA, Koornneef L, Verbeeten B Jr., Peeters FLM, Zonneveld FW, Bras J. Ophthalmology 1991; 98: 1737- 43 ( Nov). [ Reprint requests to Dr. A. A. Eijpe, Orbital Center A2- 118, Academic Medical 1Clin Neuro- uphthalmol, Vol. 12, No. 2, ISS!! Center, Meibergdreef 9, 1105 AZ Amsterdam, The Netherlands.] The authors present four patients with epidermoid bone cysts; one involved the frontal bone, and three involved the sphenoid bone. The cysts caused orbital mass and/ or proptosis in all four patients. These tumors, which seem to arise fr~ m ectodermal elements in sites not normally contaming ectoderm, are rare in bones surrounding the orbits and are best demonstrated by high- resolution computed tomography of the orbits.

[ No reprint information given.] Eyelid Pain After Magnetic Resonance Imaginginduced Palpebral Spring Vibration. Beyer RL, Sinha S. Arch OphthalmoI1991; 109: 1503 ( Nov). [ No reprint information given.] In the first article, a letter to the editor, the authors tested stainless steel palpebral slings and gold weights in a magnetic resonance scanner for possible motion, heating, or artifact and found that both did well. They conclude that patients with such eyelid appliances can be safely scanned when necessary. The second case report notes a recurrent problem with eyelid vibration, pain, and swelling in a patient with a palpebral eyelid spring fashioned from orthodontic wire following a magnetic resonance scan. They feel the spring contained ferromagnetic metal and caution physicians to use stainless steel or plastic springs to obviate this problem. Lyn A. Sedwick, M. D.
