3-year-data of combined navigated laser photocoagulation (Navilas) and intravitreal ranibizumab compared to ranibizumab monotherapy in DME patients.

Purpose: The prospective, comparative evaluation of combined navigated laser photocoagulation and intravitreal ranibizumab in the treatment of diabetic macular edema has shown advantage of a combination therapy compared to ranibizumab monotherapy at year 1 with significantly reduced injections. The purpose of this retrospective study was to determine the long-term visual gains and need of injections in a 3 year-follow-up period.

Methods: Retrospective analysis of patients of the original study in the long-term follow-up from month 12 to 36.

Odorant Receptor 51E2 Agonist β-ionone Regulates RPE Cell Migration and Proliferation.

The odorant receptor 51E2 (OR51E2), which is well-characterized in prostate cancer cells and epidermal pigment cells, was identified for the first time as the most highly expressed OR in human fetal and adult retinal pigment epithelial (RPE) cells. Immunofluorescence staining and Western blot analysis revealed OR51E2 localization throughout the cytosol and in the plasma membrane. Additionally, immunohistochemical staining of diverse layers of the eye showed that the expression of OR51E2 is restricted to the pigment cells of the RPE and choroid.

Anti-VEGF treatment and peripheral retinal nonperfusion in patients with central retinal vein occlusion.

Purpose: To evaluate the association between the size of peripheral retinal nonperfusion and the number of intravitreal ranibizumab injections in patients with treatment-naïve central retinal vein occlusion (CRVO).

Methods: Fifty-four patients with treatment-naïve CRVO and macular edema were included. Each patient underwent a full ophthalmologic examination including optical coherence tomography imaging and ultrawide-field fluorescein angiography.

Peripheral retinal non-perfusion and treatment response in branch retinal vein occlusion.

Aim: To evaluate the association between the size of peripheral retinal non-perfusion and the number of intravitreal ranibizumab injections in patients with treatment-naive branch retinal vein occlusion (BRVO) and macular edema.

Methods: A total of 53 patients with treatment-naive BRVO and macular edema were included. Each patient underwent a full ophthalmologic examination including optical coherence tomography (OCT) imaging and ultra wide-field fluorescein angiography (UWFA).

Evaluation of the New "SAVE" Protocol in Diabetic Macular Edema Over the Course of Anti-VEGF Treatment.

Background: To evaluate a recently established grading protocol for diabetic macular edema (DME) over the course of intravitreal anti-VEGF treatment with ranibizumab.

Methods: Fluorescein angiography images and optical coherence tomography scans before treatment and after 3 monthly applied intravitreal ranibizumab injections were retrospectively graded for each included study eye according to the recently introduced "SAVE" grading protocol ("S"= subretinal fluid; "A"= "area of retinal thickening"; "V"="vitreo-retinal abnormalities"; "E"="etiology of leakage focal versus non-focal") and correlated with best-corrected visual acuity (BCVA) in letters (lett).

Results: Five of the 39 included study eyes had subretinal fluid ("S") before treatment which resolved during treatment.
