Reprinted from Annals or Ophthalmology, January. 1897. A pecUTjar case of sarcoma of the CHOROID. By G. Griffin Lewis, M. 1).. SYRACUSE, N. Y Mr. H. C. D,,age 59, white, married, first consulted me on June 15, 1896, complaining- of an inability to see with his right eye. He gave the following history: Four months previous he noticed a blurring of the vision in his right eye, which gradually increased but was ac- companied by no other symptoms except a slightly dull, aching pain in the right temple, which was of an intermittent character. His fam- ily history was good, and he had never been sick a day in his life, with the exception of an occasional cold, until three years previous, when, according to his son, who was the attending physician at the time, he suffered from valvular insufficiency of the heart, the action of which has ever since been more or less irregular and changeable. I also learned from the patient that just after recovering from this sickness, while running to a fire one evening, one of the conjunctival vessels of the right eye ruptured, producing considerable ecchymosis. The tension of the eye balls was normal, the pupillary reflex nor- mal in both eyes and his urine normal, but his arteries were athero- matous. Examination of the right eye revealed a posterior polar cata- ract, which was so far advanced that a view of the fundus with the ophthalmoscope was impossible, and the vision in that eye was entirely gone with the exception of an ability to distinguish shadows from below. He was also unable to recognize reflected light when thrown into the eye from various directions, excepting when coming from below, a fact which plainly indicated that some pathological process had taken place within the fundus. Taking into consideration the condition of the patient's heart and arteries, and remembering his statement regarding the conjunctival hemorrhage, which was, in all probability, due merely to the exertion of running, I diagnosed the case as one of intra-ocular hemorrhage following cataract. The cataract was of rapid development ami was no doubt due to mal-nutrition of the lens, caused by some pathological process within the same eye, as the lens of the fellow eye was perfectly normal, and the intra-ocular hemorrhage evidently did not take place until after the cataract was sufficiently mature to shut off the vision, as there was no sudden but a gradual loss of sight. The vision of his left eye was 18/100, and with a +2.25 S. lens was brought up to 18/20. This I prescribed for distant use. together with a +5.00 S. for reading. On August 6th, three weeks later. 1 was called to his house and found him suffering considerable pain through his right temple and on top of his head. His pulse was only 48, the lids of his right eye were badly swollen and the ocular conjunctiva so oedematous that it overlapped the cornea around its whole circumference. This attack, 1 was informed, had come on suddenly with pain from the begin- 2 ning. The tension was considerably increased, and, concluding that he had had another intra-ochlar hemorrhage, I applied leeches to the temple, instilled a two-grain solution of eserine sulphate, ami applied locally lead and opium wash. This treatment relieved him so much that he got a fairly good night's rest. The eserine seemed to keep the tension down some- what, tint as there was still some pain. 1 tapped the anterior cham- ber. using a cataract needle with a broad blade and a narrow shank, and the fluid which escaped was as black as ink. This operation was an immediate and permanent relief to the patient from all actual pain, but as the eye still remained sensitive and 1 was afraid of sympathetic ophthalmia. I advised enucleation. 'Phis he dreaded and consequently kept putting it off. After a couple of weeks a small distinct hemorrhage, a little larger than a pinhead, appeared on the anterior surface of the lens. This was followed several weeks later by photophobia and lachrymation of the left eye, ami the patient then decided to have the offending organ removed. On October 7th. with the assistance of Dr. Arthur Breese, who administered ether. I enucleated the eye, and on the same evening, in the presence of Dr. Breese, I dissected it. The anterior chamber was filled with a fluid of the consistency and color of ordinary writing ink, the lens was cataractous, the cili- ary process hardened, tin* vitreous disintegrated and its chamber tilled with a thin bloody fluid. There was a small detachment of the retina just below the optic disc, and the disc was somewhat cupped, but what was of particular interest ami that which leads me to report the case, was a small black tumor, about the size of a duck-shot, on the outside of the siderotic coat about a quarter of an inch to the nasal side of the optic nerve; and on the inside of the eye, at a posi- tion corresponding to that of the tumor, was a small dimple, which gave the appearance of a portion of the retina and choroid having been pulled through a small opening in the sclera. Upon dissect- ing the tumor I found it to consist of a perfectly white substance surrounded by what seemed to be the sclerotic coat. I sent the speci- men to Dr. William May for microscopical examination, and he pro- nounced it a round celled sarcoma. In all probability it sprang from th 1 choroid, but, contrary to the usual rule, it had. for some inconceivable reason, taken the course of the greater resistance and grown outward, pushing with it the sclera, which enveloped it like an orange is enveloped by its skin. Whether or not this tumor was in any way associated with the intra-ocular hemorrhage, it is difficult to say. At all events, the case is one of the utmost interest, not only on account of its unsus- pected presence and the relative infrequency of this variety of neo- plasm, but more especially because it took the course of greater resistance, pushing the sclera before it. ami was not attended by any growth or bulging within the globe, a fact which is beyond com- prehension, and a similar instance of which 1 am unable to find in ophthalmologieal literature. The opportunities of examining such a growth in this location in an early stage of its development are rare, and I only regret that 1 did not suspect its nature at the time I made the dissection and save the whole globe for future observation and study. It is fortunate for the patient that the removal of the eye has given him a better chance of escaping both local recurrence and metastatic deposits.
