On May 16, slight ptosis was noticed on the right side. This symptom is yet present. On May 19 the circumcorneal injection was much less; the conjunctival hyperæmia and lachrymation were still present, while the ptosis was slightly increased and tension was + 1. At the present date—July 23, 1899—this patient has no pain. The retinal arteries are increased in size. Tension is + 1. Vision has increased from light perception to ability to count fingers at three feet. The conjunctival injection which followed the operation has disappeared; the optic nerve has a color more approaching the normal. The ptosis is less. This was the first sympathectomy made in America for glaucoma. CASE II.—DOUBLE SYMPATHECTOMY FOR GLAUCOMA SIMPLEX. Miss M. E., a German, aged forty-three, was sent to me on June 14, 1899. For two years sight had been failing, until at this time vision was as follows: R. E. = 0; L. E = light perception. Tension was + 3. Both optic nerves showed marked cupping of the disk; the vessels were pushed to the nasal side. She stated that she had never had pain in the eyes, and had not consulted an ophthalmic surgeon. I advised her to submit to an excision of the left superior cervical ganglion; she consented, and on June 15 the operation was performed by myself, assisted by Dr. E. C. Renaud, at St. Joseph’s Sanatorium, in the presence of Drs. J. C. Murphy, A. R. Kieffer, and S. A. Grantham. The operation was difficult, owing to the abnormal position of the vagus nerve. This was outside of and external to the carotid sheath, and was much smaller than normal; it was not larger in diameter than the head of a pin. It was identified by irritating it and watching the effect on the heart. The superior cervical ganglion was removed and one-half inch of the trunk of the sympathetic below. Shortly after the operation there were lachrymation, ocular congestion, and contraction of the pupil on the corresponding side. On the second day she counted fingers at 2½, and on the third at 3½ feet. Slight ptosis was present. She left the hospital on the eighth day. At this time she counted fingers at four feet. There was only slight, if any, reduction of tension during the eight days she was in the hospital. In counting fingers she saw with the nasal side of the retina—temporal field. I did not see her again until June 30, and she was then counting fingers at five feet. Tension on that day was normal. She had light perception in the right eye. On July 16 I excised the right superior cervical ganglion without difficulty, and on July 7 she counted fingers at seven feet with the left eye, and could see the hand at four inches with the right. I examined her on July 20, when vision remained the same, the tension of the right eye was + 1, and of the left + 2. She was well pleased to have the small amount of vision she possessed. CASE III.—SYMPATHECTOMY FOR OPTIC-NERVE ATROPHY.
