Functional and morphological changes in diabetic macular edema over the course of anti-vascular endothelial growth factor treatment.

Purpose: To evaluate macular morphology and function in diabetic macular edema (DME) over the course of intravitreal anti-vascular endothelial growth factor (VEGF) treatment with Ranibizumab.

Methods: A consecutive series of 39 study eyes with centre-involving DME were included in this study. In all subjects, best-corrected visual acuity (BCVA) according ETDRS protocol, fluorescein angiography (FA), microperimetric macular sensitivity (MP) and Spectral Domain optical coherence tomography (SD-OCT) cross-sectional scans were obtained before treatment and after 3 monthly applied intravitreal Ranibizumab injections.

Improvement of diabetic retinopathy with intravitreal Ranibizumab.

This study indicates that in addition to the significant improvement in visual acuity and reduction of central retinal thickness in patients with center-involving diabetic macular edema, intravitreal anti-VEGF treatment with Ranibizumab may also lead to a significant stabilization or even improvement of diabetic retinopathy.

Pain and accuracy of focal laser treatment for diabetic macular edema using a retinal navigated laser (Navilas).

Aim: To investigate treatment-related pain and the accuracy of navigated laser photocoagulation in the treatment of clinically significant macular edema.

Methods: Focal laser treatment of diabetic macular edema in 54 consecutive patients was digitally planned on fundus images and performed using the navigated laser photocoagulation system Navilas(®) (OD-OS GmbH, Teltow, Germany). Treatment-related pain was quantified on a visual analog scale directly after treatment and compared with a matched control group who received conventional laser treatment (n = 46).
