Diabetic retinopathy among Brazilian Xavante Indians.

Background: To describe the frequency of diabetic retinopathy (DR) and its associated variables in Brazilian Xavante Indians.

Methods: A population-based survey carried out in two Xavante Reservations between 2008 and 2012, included 948 Indians aged 20 years or more, identified 246 individuals with type 2 diabetes. A non-probabilistic cluster sample of 140 diabetic individuals were submitted to ophthalmologic examination.

Scleral thickness following fluocinolone acetonide implant (Retisert).

Purpose: To evaluate whether intravitreal fluocinolone acetonide (FA) implantation (Retisert) leads to scleral thinning.

Methods: Scleral thickness was measured at the pars plana region (4 quadrants) with anterior segment OCT (Visante) in FA implanted eyes (18) with noninfectious posterior uveitis in comparison to eyes with prior vitrectomy (8), and normal eyes without prior surgery (30).

Results: Mean scleral thickness in normal (nonsurgical) eyes was 0.

Evaluation of injection frequency and visual acuity outcomes for ranibizumab monotherapy in exudative age-related macular degeneration.

Objective: To evaluate the visual outcomes for intravitreal ranibizumab administered on an as-needed basis for exudative age-related macular degeneration (AMD) and to investigate the relationship between injection frequency and visual outcome in this setting.

Design: Retrospective, interventional case series.

Participants: A total of 131 eyes with treatment-naïve, exudative AMD undergoing ranibizumab monotherapy.

Dynamic evaluation of sutureless vitrectomy wounds: an optical coherence tomography and histopathology study.

Purpose: To investigate the in vitro dynamic wound morphology of fresh 25- and 23-gauge sutureless sclerotomy wounds.

Design: Experimental study; laboratory investigation.

Participants: Sixteen eyes of New Zealand white rabbits.

Evaluation of wound closure in oblique 23-gauge sutureless sclerotomies with visante optical coherence tomography.

Purpose: To investigate the in vivo real-time wound morphology of fresh 23-gauge sutureless oblique sclerotomy wounds with anterior segment optical coherence tomography (OCT).

Design: Prospective, observational case series.

Methods: Subjects underwent three-port pars plana vitrectomy with a 23-gauge trocar/cannula microincision surgical system at the Cole Eye Institute.
