Retinal periarteritis secondary to syphilis.

A 43-year-old black woman showed ophthalmoscopic evidence of retinal arteriolitis two weeks after being treated for uniocular panuveitis. Angiographic examination suggested that these deposits were not intraluminal or endothelial atherosclerotic emboli or plaques, but were deposits in the outer walls of retinal arterioles. Sequential ophthalmoscopic and angiographic examinations at one-month intervals for 12 months showed no progression or change in location of these deposits.

Prevention of corneal opacification in open sky vitrectomy: Part I. An in vitro study.

We tested the effects of various physiologic solutions with known osmotic pressures on maintenance of corneal transparency in vitro and compared them with the effects of other solutions that exert both oncotic and osmotic pressures. Normal saline solution, 5% glucose and normal saline solution, tissue culture 199, and plasma were bathing solutions tested. Increases in hydration and endothelial cell damage for the various media were compared.

Surgical treatment of exotropia after surgically produced pseudoparalysis of the medial rectus muscle.

The characteristic clinical findings of pseudoparalysis of the medial rectus muscle include exotropia in primary position, widened medial fissure on the affected side, limitation of adduction on the affected side, an A-pattern exotropia, and a paradoxical forced-traction test. We have devised a surgical technique to restore good movement of the eye in adduction. The priniciple behind the technique is that all adhesions between Tenon's capsule covering the muscle and conjunctiva, and between muscle and sclera must be found and cut posterior to the fornix.
