Purpose: In vitro and in vivo studies did not detect toxicity to the retinal pigment epithelium cells using intravitreal ziv-aflibercept. Our purpose is to ascertain the 3-month safety and efficacy in wet age-related macular degeneration (AMD) treated with intravitreal ziv-aflibercept.
Methods: Prospectively, consecutive patients with wet AMD underwent ziv-aflibercept intravitreal injection (1.25 mg/0.05 mL) from March 2015 to November 2015. Monitoring of best-corrected visual acuity, intraocular inflammation, cataract progression and by spectral domain optical coherence tomography were carried out at baseline day 1, 1 week, 1 month, 2 months and 3 months after injections.
Results: 30 eyes were treated (22 Caucasians, 8 Indians; 16 men, 14 women; 14 right eyes and 16 left eyes) with mean age of 74.3 years with 11 treatment-naïve cases and 19 having had treatment-non-naïve. Best-corrected visual acuity improved from baseline logMAR 1.08-0.74 at 1 week, 0.72 at 1 month, 0.67 at 2 months and 0.71 at 3 months (p<0.001 for all time periods). Central macular thickness in microns decreased from 332.8 to 302.0 at 1 week, 244.8 at 1 month, 229.0 at 2 months and 208.2 at 3 months (p<0.001 for all time periods). There were no signs of intraocular inflammation, or change in lens status or increase in intraocular pressure throughout the study.
Conclusions: Off label use of ziv-aflibercept improves visual acuity, without detectable ocular toxicity and offers a cheaper alternative to the same molecule aflibercept, especially in low/middle-income countries and in countries where aflibercept (Eylea) is not available.

Background: Age-related macular degeneration (AMD), a condition of multifactorial origin, is a major cause of irreversible vision loss in industrialized countries. The dry late stage of the disease, known as geographic atrophy (GA), is characterized by progressive loss of photoreceptor cells and retinal pigment epithelial cells in the central retina. An estimated 300 000 to 550 000 people in Germany suffer from GA.

Purpose: The purpose of this study was to develop ground-truth histology about contributors to variable fundus autofluorescence (FAF) signal and thus inform patient selection for treating geographic atrophy (GA) in age-related macular degeneration (AMD).
Methods: One woman with bilateral multifocal GA, foveal sparing, and thick choroids underwent 535 to 580 nm excitation FAF in 6 clinic visits (11 to 6 years before death). The left eye was preserved 5 hours after death.

We hypothesized that a strategy employing tissue-specific endothelial cells (EC) might facilitate the identification of tissue- or organ-specific vascular functions of ubiquitous metabolites. An unbiased approach was employed to identify water-soluble small molecules with mitogenic activity on choroidal EC. We identified adenosine diphosphate (ADP) as a candidate, following biochemical purification from mouse EL4 lymphoma extracts.

Background: Human anterior lens capsules (ALCs) have great potential in the treatment of multiple eye diseases, including corneal ulcers, glaucoma, age-related macular degeneration and macular holes. ALCs are also regarded as promising scaffolds for various ocular cells. Here, we investigated different decellularization methods for removing lens epithelial cells (LECs) that adhered to ALCs.
