Show 274 LITERATURE ABSTRACTS bismus patients to inject the levator in 25 patients in order to induce a protective ptosis. All patients had been considered for tarsorraphy for various corneal disorders (herpes simplex keratitis, alkali bum, neuroparalytic keratitis, etc.). Ptosis lasted from 1 to 5 weeks (mean of 16 days) with complete recovery in all patients. As the authors conclude, "because of its simplicity and efficacy, it [botulisminduced ptosis] is a useful technique and it may be considered for the treatment of 'slow-to-heal' corneal ulcers and to protect eyes exposed by neurologic dysfunction."

Saunders, 171 Ashley Ave., Charleston, SC 29425-2236.] Nine patients, four children and five adults, underwent medical rectus recession combined with inferior and superior rectus tendon transposition for Duane's syndrome or sixth nerve palsy. All of the adult patients developed anterior segment ischemia, even one who had a 6 month respite between medial rectus and transposition surgery, but all did well eventually. The authors advise great caution in performing such surgery in adult patients. Lyn A. Sedwick, M.D. Maternal Orbital Hematoma Associated With Labor.

Oak Ave., Marshfield, WI 54449.] Two women experienced sudden diplopia and proptosis during labor. Computerized tomographic scanning and orbital ultrasound demonstrated orbital hematoma that eventually resolved spontaneously in both patients. Lyn A. Sedwick, M.D. !

Guyton, Wilmer Bl-35, Johns Hopkins Hospital, Baltimore, MD 21205.] The authors have created monocular diplopia by inducing spherical refractive error, either hyperopic or myopic, which was always alleviated with a pinhole. An erudite discussion of optics is given, but the real point is to recognize that minor amounts of uncorrected refractive error can lead to complaints of monocular diplopia. Lyn A.

Kinyoun, Department of Ophthalmology RJ-10, University of Washington, Seattle, WA 98195.] This article is interesting because four of the five cases of radiation retinopathy presented occurred in patients who received 2000 rads to the orbits, known to be divided into 10 fractions over 2 weeks in two of four patients, for Graves' disease. Four of five had a rather poor visual outcome in spite of laser treatment. This is a nice article to share with your aggressive radiotherapists who urge you to treat isolated proptosis or extraocular muscle imbalance with this potentially harmful modality. Lyn A.
