Immediate postoperative use of a topical agent to prevent intraocular pressure elevation after pars plana vitrectomy with gas tamponade.

Objective: To determine whether a single topical aqueous suppressant applied immediately after pars plana vitrectomy with long-acting gas tamponade prevents intraocular pressure (IOP) elevation.

Methods: Fifty patients who met the inclusion criteria and underwent pars plana vitrectomy with long-acting gas tamponade were randomized to receive a combination of timolol maleate and dorzolamide hydrochloride, long-acting timolol alone, dorzolamide alone, or placebo at the conclusion of surgery. The IOP was checked by a portable, handheld tonometer (Tono-Pen) at the conclusion of surgery and at 5 hours, 1 day, and 1 week after surgery.

Salvage external beam radiotherapy of retinal capillary hemangiomas secondary to von Hippel-Lindau disease: visual and anatomic outcomes.

Objective: To examine the visual and anatomic outcomes of patients with retinal capillary hemangiomas secondary to von Hippel-Lindau (VHL) disease treated with globe-salvaging fractionated external beam radiotherapy (EBRT) after progression of hemangiomas despite initial therapy.

Design: Retrospective noncomparative consecutive case series.

Participants: Review of medical records of 5 patients with retinal capillary hemangiomas secondary to VHL disease.
