Effect of intravitreal dexamethasone solution on the reduction of macular thickness in pseudophakic diabetic patients in a public hospital in Brazil: a randomized clinical trial.

Purpose: To determine the effect of short-term 4 mg/mL dexamethasone solution treatment in diabetic macular edema (DME).

Patients And Methods: Twenty-seven pseudophakic diabetic patients with visual impairment caused by DME were randomized to receive 0.01 mL (40 μg), 0.

Cryotherapy vs laser photocoagulation in scleral buckle surgery: A randomized clinical trial.

Objective: To compare the reattachment rate and visual acuity results among patients with rhegmatogenous retinal detachment who underwent scleral buckle surgery with retinopexy by intraoperative cryotherapy (cryopexy) vs postoperative (1 month later) laser photocoagulation (laserpexy).

Methods: Eighty-six patients with rhegmatogenous retinal detachment scheduled for scleral buckle surgery were randomly assigned to the cryopexy or laserpexy group.

Main Outcome Measures: The primary outcome was the 1-week reattachment rate.
