Comparison of the effect of ranibizumab and dexamethasone implant in diabetic macular edema with concurrent epiretinal membrane.

Objective: To compare the efficacy and safety of intravitreal ranibizumab (RZB) injections and intravitreal dexamethasone (DEX) implant in diabetic macular edema (DME) with concurrent epiretinal membrane (ERM).

Methods: This was a retrospective, observational, comparative study. Medical records of DME patients with concurrent ERM were retrospectively reviewed.

The Distribution of the Photoreceptor Outer Segment Length in a Healthy Population.

Purpose: To evaluate the effects of age and sex on the photoreceptor outer segment (PROS) length in healthy eyes, using spectral-domain optical coherence tomography (SD-OCT).

Methods: A total of 97 eyes of 97 healthy participants (spherical equivalent < ±1 diopters [D]) were scanned with SD-OCT. The patients were divided into 3 groups by age: group 1 (0-20 years), group 2 (21-40 years), and group 3 (41-60 years).
