RESUMO
Intraocular metallic-appearing foreign bodies in the anterior segment were seen in six eyes after cataract extraction by two-handed phacoemulsification. These fragments produced no symptoms and had no clinically significant effect on visual function. Similar-appearing foreign bodies were experimentally produced by applying ultrasound power with a phacoemulsification handpiece to the surface of a cyclodialysis spatula in vitro. Microscopic examination of the phaco handpiece tip and cyclodialysis spatulas revealed numerous surface irregularities, suggesting a possible source of these fragments. These results suggest that instrument touch during phacoemulsification may be the cause of the fragments. Long-term follow-up of these patients is required to determine the overall effect of the fragments.

Uveitis is an extraintestinal complication of ulcerative colitis and Crohn's disease. In most cases, its course parallels that of the underlying bowel disease and improves with its therapy. Occasionally, the two processes are not synchronous. In either case, the uveitis has usually been considered to be dependent on the presence of the colon. This report describes a patient who developed uveitis shortly after colectomy and ileal-rectal sleeve anastomosis for ulcerative colitis, indicating that the continuing presence of the colonic mucosa is not necessary for development of the associated ocular inflammation.

Acute retinal necrosis represents a distinct, recently recognized clinical syndrome. Four patients who presented with rapid visual loss associated with uveitis and coalescent areas of retinal necrosis, followed by development of retinal detachments were examined. This paper emphasizes the following: (1) unilateral involvement does occur, (2) the distribution of lesions can be peripheral or central, and (3) early lesions are not associated with retinal vascular abnormalities either clinically or angiographically. Signs and symptoms are suggestive of an infectious process, possibly viral.
