Hydatid Cyst of the Orbit.
—At the Ophthalmological Society of London, December 13, 1888, Dr. Rockliffe brought forward a case of suppurating hydatid cyst of the orbit. The patient, a laborer aged 33, had first noticed an affection of the sight of the left eye in 1882. He had several attacks of inflammation in it, and the vision gradually deteriorated till, in April, 1887, he was quite blind with it. There was then marked protrusion, some ptosis, and the action of all the ocular muscles, except the external rectus, was very limited. Nothing definite was made out as to the condition of the orbit. Eighteen months later, having had more attacks of pain, the patient consented to an operation. An exploratory puncture with a scalpel having given no results, the orbit was more freely opened up and, the eye being removed, a suppurating hydatid cyst was found at the apex
