Single wound, in situ tying technique for iris repair.

The authors describe a technique for placing and tying interrupted iris sutures in virtually any area of the iris using only a single limbal paracentesis wound. The tying is performed with conventional knot-forming techniques outside the eye before the throws are pulled into the anterior chamber and tightened with the desired 180 degrees tension on the suture ends. During suture tying, the iris stays in situ rather than being stretched and distorted.

Tricholemmoma of the eyelid.

Tricholemmoma is a benign cutaneous tumor that shows differentiation characteristic of the outer hair sheath. The usual site of occurrence is the face, including the nose and eyelid. Four cases of tricholemmoma involving the eyelid margin to a variable extent are presented and the clinical and pathologic findings are reviewed. In three of the four cases, a histopathologic misdiagnosis of squamous cell carcinoma was initially made. In one case, this resulted in a greater sacrifice of normal lid tissue than was necessary, although the reconstruction yielded a good result. In the subsequent cases, the entity of tricholemmoma was well appreciated before definitive oculoplastic surgery and the referring diagnosis of squamous cell carcinoma was refuted.

Delayed hypotony, shallow anterior chamber, and choroidal detachment in the postoperative cataract eye. A comparative study of closure with 7-0 silk, 9-0 silk, and 9-0 nylon.

To determine the time relationships between hypotony, choroidal detachment, and shallowing of the anterior chamber, an initial 64 eyes closed with 7-0 black silk were studied with applanation tensions, indirect ophthalmoscopy, and slit lamp examinations before surgery and for six weeks after cataract extraction. Applanation tension less than 6 mm Hg was detected in 72% of eyes, choroidal detachment in 44%, and shallowing of the anterior chamber in 28%. Low intraocular pressure was always detected at the same time or before either choroidal detachment or shallow anterior chamber. The peak period when pressure dropped to less than 6 mm Hg was shortly before 12 to 14 day suture removal or the day after. Suture tract leakage appears to be the predominant mechanism triggering this hypotony. Hypotony is prolonged past the leakage period, probably by ciliary body detachment. This 7-0 silk closure group is compared with 53 eyes closed with 9-0 virgin silk and 45 eyes closed with 9-0 nylon. Both of these latter groups showed substantially lower incidences of hypotony, choroidal detachment, and shallowing of the anterior chamber.
