Background Chronic activation of the innate immune system is a hallmark of retinal degenerative diseases, including age-related macular degeneration (AMD). Overt microglia and macrophage reactivity, as well as dysregulation of the alternative complement system, trigger and sustain retinal degeneration. It is now accepted that there exists a vicious cycle of mononuclear phagocyte reactivity, abnormal intrinsic complement activation, damage of Bruch's membrane, dysfunction of the retinal pigment epithelium, photoreceptor degeneration and choroidal neovascularization (CNV)...

Ocular neovascularization underlies major blinding eye diseases such as "wet" age-related macular degeneration (AMD). Despite the successes of treatments targeting the vascular endothelial growth factor (VEGF) pathway, resistant and refractory patient populations necessitate discovery of new therapeutic targets. Using a forward chemical genetic approach, we identified the heme synthesis enzyme ferrochelatase (FECH) as necessary for angiogenesis in vitro and in vivo FECH is overexpressed in wet AMD eyes and murine choroidal neovascularization; siRNA knockdown of Fech or partial loss of enzymatic function in the Fech(m1Pas) mouse model reduces choroidal neovascularization...

INTRODUCTION: Pathological formation of blood vessels plays a key role in the growth and metastasis of tumors and also in several serious ophthalmological diseases such as wet age-related macular degeneration (AMD) or diabetic retinopathy. In AMD treatment, aflibercept (tradename EYLEA(®)) is used to deactivate the underlying pathological neovascularisation. Aflibercept is a recombinant fusion protein which binds to vascular endothelial growth factor (VEGF) receptors, thereby inhibiting VEGF pathway activation...

Age-related macular degeneration(AMD) is one of the main leading causes of irreversible vision damage in patients over 50 years old. Genetic factors play an important role in the occurrence and development of AMD. Since the significant correlation between complement factor H (CFH) gene and AMD was found, the pharmacogenomics of CFH polymorphism was paid close attention by academic circles. Among which, studies concerning CFH Y402H were more deeply. Studies have found CFH Y402H genotypes might lead to differences toward the outcome of PDT and anti-VEGF treatment...

OBJECTIVE: Economic evaluations in wet age-related macular degeneration (ARMD) is hampered as often utility values for solely one eye are used, mostly the better-seeing eye (BSE). Moreover, frequently chosen methods rely on patient values and/or disease specific measures, while economic evaluations prefer generic quality of life (QoL) measures based on societal preferences. The generic QoL utility instrument EQ-5D has shown to be insensitive for differences in visual acuity. The aim of this study was therefore to provide societal utility values, using the generic SF-6D, for health states acknowledging both BSE and worse-seeing eye (WSE)...

PURPOSE: The advent of spectral domain optical coherence tomography has led to superb imaging capabilities in addition to enhanced visualization of the retinal layers. Such advancements have led to the identification of a variety of new retinal conditions, including outer retinal tubulations (ORTs). ORTs are ovoid hyporeflective spaces located in the outer retina. The pathogenesis is unclear but seems to involve sublethal injury to the photoreceptors leading to a compensatory reorganization of the photoreceptor layer with the neighboring ellipsoid zone resulting in a hyperreflective border surrounding a central lumen...

Tumor necrosis factor alpha (TNFα)-induced angiogenesis plays important roles in the progression of various diseases, including cancer, wet age-related macular degeneration, and rheumatoid arthritis. However, the relevance and role of vascular cell adhesion molecule-1 (VCAM-1) in angiogenesis have not yet been clearly elucidated. In this study, VCAM-1 knockdown shows VCAM-1 involvement in TNFα-induced angiogenesis. Through competitive blocking experiments with VCAM-1 Ig-like domain 6 (VCAM-1-D6) protein, we identified VCAM-1-D6 as a key domain regulating TNFα-induced vascular tube formation...

BACKGROUND: People who suffer from wet age-related macular degeneration (AMD) risk central vision loss. Treatment with anti-VEGF is the only available option at present that preserves vision and no definitive cure currently exists. Patients feel that they are compelled to accept this treatment because they might otherwise become blind. AIM: To identify and describe nursing actions performed by nurses that create a sense of good nursing care in patients with wet (AMD)...

A critical target tissue in age-related macular degeneration (AMD) is the retinal pigment epithelium (RPE), which forms the outer blood-retina barrier (BRB). RPE-barrier dysfunction might result from attenuation/disruption of intercellular tight junctions. Zonula occludens-1 (ZO-1) is a major structural protein of intercellular junctions. A connexin43-based peptide mimetic, αCT1, was developed to competitively block interactions at the PDZ2 domain of ZO-1, thereby inhibiting ligands that selectively bind to this domain...
