To evaluate the role of the vitreous in the management of diabetic macular edema with ranibizumab intravitreal injections in a pro re nata regimen. Prospective study of 50 consecutive eyes with diabetic macular edema treated with ranibizumab and 12 months of follow-up. Primary endpoint: to assess differences between non-vitrectomized and vitrectomized eyes in the number injections needed to control the edema.

Aim: Diabetic retinopathy staging system and progression predictors are soon to be considered insufficient for ophthalmologic practice. Given the growing evidence of the role of choroidal dysfunction, our purpose was to assess choroidal vascular changes with intravitreal ranibizumab (RBZ) treatment in diabetic macular edema (DME).

Methods: This was a prospective longitudinal cohort study.

Hereditary gelsolin amyloidosis is a rare subtype of hereditary systemic amyloidosis. An old male presented with the characteristic triad of symptoms, including bilateral facial palsy, cutis laxa, and corneal lattice amyloidosis. The diagnosis was confirmed by the detection of the mutation in gelsolin gene located on chromosome 9.

Aim: To evaluate the efficacy of switching from bevacizumab to ranibizumab or aflibercept in eyes with diabetic macular edema (DME) unresponsive to bevacizumab.

Methods: Single-center retrospective comparative study of patients with DME unresponsive to intravitreal bevacizumab that was switched to ranibizumab or aflibercept. Best-corrected visual acuity (BCVA) and central foveal thickness (CFT) were analysed prior to and 4 months after the switch.

Background: A new approach to address focal vitreomacular adhesion in patients with diabetic macular edema may control and stabilize diabetic macular edema with fewer anti-vascular endothelial growth factor injections.

Objectives: The aim of this study was to demonstrate that diabetic macular edema can be improved by inducing the release of a vitreomacular adhesion, with less than 2500 μm, with enzymatic vitreolysis.

Methods: From a retrospective analysis of clinical records from patients with diabetic retinopathy, patients with diabetic macular edema and vitreomacular adhesion <2500 μm were selected for a single-arm prospective study.

Purpose: To evaluate pars plana vitrectomy (PPV) outcomes in cases with tractional diabetic macular edema (tDME).

Methods: We conducted a single-center retrospective study with a follow-up of 12 months. Forty-six eyes with tDME of 38 patients submitted to PPV between 2013 and 2015 were assessed.
