Are the effects of hemodialysis on ocular parameters similar during and after a hemodialysis session?

Purpose: To evaluate the changes in several ocular parameters, including choroidal thickness, during and after hemodialysis.

Methods: Twenty-seven eyes of 27 patients with chronic renal failure undergoing hemodialysis were included. The patients underwent an ophthalmic examination, including intraocular pressure, central corneal thickness, iridocorneal angle, subfoveal choroidal thickness, and blood pressure, just before a hemodialysis session, during the second hour of the session, and half an hour after the end of the session.

Primary 23-gauge vitreoretinal surgery for rhegmatogenous retinal detachment.

Aim: To report the effectiveness and safety of primary 23-Gauge (G) vitreoretinal surgery for rhegmatogenous retinal detachment (RRD).

Methods: In this retrospective study, 49 eyes of 49 consecutive patients who underwent primary 23-G transconjunctival sutureless vitrectomy (TSV) for RRD between January 2007 and July 2009 at our institution were evaluated.

Results: Mean follow-up time was 8.
