Retrospective analyses of optical coherence tomography in recurrent macular edema following intravitreal therapy in patients with retinal vein occlusion.

Background: Optical coherence tomography has focused mainly on central subfield thickness to quantify macular edema in central and branch retinal vein occlusion. We examined macular fields other than the central subfield to determine if they are possibly independent indicators of recurrent macular edema.

Methods: Single center, retrospective, consecutive case study of patients with recurrent macular edema secondary to either central or branch retinal vein occlusion.

Sterile endophthalmitis rates and particle size analyses of different formulations of triamcinolone acetonide.

Purpose: To evaluate the rate of sterile endophthalmitis (SE) following intravitreal injection of three different formulations of triamcinolone acetonide (TA) in a single physician practice and also to assess the mean diameter and concentration of particles of the two TA formulations currently available commercially in the USA. It was hypothesized that TA formulations with smaller particles and/or greater concentrations would have a higher incidence of SE.

Methods: Single-site, interventional case series in which the medical records of 392 consecutive eyes receiving intravitreal TA as Triesence(®), Kenalog(®)-40, or preservative-free TA between September 2008 and October 2013 were retrospectively reviewed for the incidence of SE.
