Long-term follow-up of leiske closed-loop anterior chamber intraocular lenses.

Purpose: To provide long-term follow-up on the rates of endothelial cell loss in eyes with retained closed-loop anterior chamber intraocular lenses (IOLs).

Setting: Private practices, Chicago, Illinois, USA.

Methods: In 1980 to 1982, 3 surgeons performed 587 intracapsular cataract extractions with implantation of Leiske closed-loop anterior chamber IOLs.

Surgical management of subluxed posterior-chamber intraocular lenses.

Objective: To formulate a systematic approach to the surgical management of subluxed posterior-chamber intraocular lenses (IOLs).

Design: We reviewed the records of 31 consecutive patients who underwent anterior-segment surgery for IOL subluxation. Presumed anatomic causes of IOL subluxation were identified in 28 cases (90%).

Studies on the site of action of vasopressin in inducing adrenocorticotropin secretion.

Hypophysectomized rats bearing three transplanted pituitaries under the kidney capsule responded to synthetic lysine vasopressin or pitressin with a significant elevation of plasma corticosterone, whereas hypophysectomized rats with no grafts did not. This response was completely abolished by pretreatment of animals with dexamethasone but was unaltered by central hypothalamic destruction. Corticotropin-releasing factor content of the hypothalamic median eminence, hypophyseal stal-, or pars nervosa of the posterior pituitary of intact rats was unchanged 5 or 10 min after ip injection of vasopressin compared to the basal level.
