Case 1—A 6-year-old white girl had had the appearance of a "small right eye" for seven months that was actually proptosis of the left eye; it had been particularly noticeable for four days prior to our first examination of her in November 1973. Visual acuity was R.E.: 20/20, and L.E.: 20/30. There was slight limitation in abduction and elevation of the left eye. The left pupil was 1 mm larger than the right and had a Marcus-Gunn response. The left optic disk margin was blurred, with one flame-shaped hemorrhage nearby. The left eye was 5.5 mm proptotic and was 2 mm below the level of the right eye. A slight resistance occurred in retrodisplacing the left eye. Perimetric tests showed an enlarged blind spot on the left. Optic foramen x-ray views revealed an optic canal, 7 mm in diameter, on the right side and an 8-mm canal on the left. Pneumoencephalography was normal, and showed no evidence of abnormality in the optic chiasm. Optic nerve glioma was suspected, but because we lacked documentation and had a variety of different opinions regarding management of this disease,2 we explored the orbit for histologic confirmation. In December 1973, the patient underwent a modified Kronlein orbitotomy8 of the left orbit. The optic nerve, strikingly enlarged from the globe to the optic foramen, was about 10 mm in From the Department of Ophthalmology, University of Illinois Eye and Ear Infirmary, Chicago, Illinois. This study was supported in part by an unrestricted grant from Research to Prevent Blindness, Inc., New York, New York.

N2 - We used the retinal cryoprobe in the surgical management (biopsy and excision) of orbital and ocular adnexal tumors in four patients. The strong bond between the cryoprobe tip and the tumor allowed application of moderate traction to the tumors, facilitating their removal. The amount of traction on the tumor or cyst appeared to be much greater than that caused by forceps or clamps. In one case, however, marked traction with the cryoprobe caused rupture of the tumor capsule. In another case, in which a cyst wall was entered during dissection, we applied the cryoprobe to the opening, sealing the hole with an ice ball, to keep the cyst from collapsing. Histopathologic structure was not altered by cryoprobe applications.
