Pneumatic retinopexy for retinal detachment associated with severe choroidal detachment.

Purpose: The purpose of this study was to evaluate the role of pneumatic retinopexy as an initial management of retinal detachment associated with hypotony, severe choroidal detachment, and vitritis.

Methods: Retrospective, interventional, noncomparative case series. We included nine eyes from nine patients (six women and three men) with retinal detachment associated with hypotony, severe choroidal detachment, and vitritis managed with pneumatic retinopexy (either SF6 or C3F8) as their initial management between January 1, 1992, and December 31, 2007.

Retinal pigment epithelial tears after intravitreal bevacizumab injection for exudative age-related macular degeneration.

Purpose: To determine the incidence of and the risk factors for the development of retinal pigment epithelial (RPE) tears after intravitreal bevacizumab (Avastin) injection for the treatment of exudative age-related macular degeneration (AMD).

Methods: A retrospective, multicentre, consecutive interventional case series of all patients with subfoveal exudative AMD treated with intravitreal bevacizumab between August 2005 and April 2007. The main outcome measures were pre- and post-RPE tear visual acuity and choroidal neovascular membrane lesion types, incidence of tears and time from first injection until development of the tear.

An extension of the Early Treatment Diabetic Retinopathy Study (ETDRS) system for grading of diabetic macular edema in the Astemizole Retinopathy Trial.

Purpose: To compare the effects of astemizole, an antihistamine, versus placebo on the 1-year course of diabetic macular edema (DME) and to illustrate use of a modified ETDRS system for grading areas of retinal thickening and hard exudates that may be useful in clinical trials of treatments for this disorder.

Methods: Between June 1994 and September 1997, at 2 clinics, 63 patients who had, in at least one eye (the study eye), DME that had not previously been treated with macular photocoagulation, and for which photocoagulation was not currently recommended by the investigator, were enrolled and randomly assigned to astemizole or placebo. Fifty-four of the 63 patients (86%, 26 in Clinic 1 and 28 in Clinic 2) completed 1 year of followup and had adequate 7-field stereoscopic film-based color fundus photographs of the study eye at the baseline and 1-year visits.
