In the article by Castillo et al (http://www.aaojournal.org/ article/S0161-6420(14)00728-3/fulltext), the authors provide a thoughtful review of “the accuracy of optical coherence tomography (OCT) [compared] with alternative tests for monitoring neovascular age-related macular degeneration (nAMD) and detecting disease activity among eyes previously treated for this condition.” The topic is impo...

PURPOSE To evaluate the predictive factors of long-term visual outcomes in neovascular age-related macular degeneration (nAMD) treated with antivascular endothelial growth factor (anti-VEGF) agents. METHODS Unicentric retrospective review of patients with nAMD treated with anti-VEGF agents. Visual outcomes, 12 and 60 months after diagnosis, were evaluated. In an attempt to identify predictive...

Subretinal fibrosis is a result of a wound healing response that follows choroidal neovascularization in neovascular age-related macular degeneration (nAMD). Although anti-vascular endothelial growth factor therapy has become a standard treatment that improves visual acuity in many nAMD patients, unsuccessful treatment outcomes have often been attributed to the progression of subretinal fibrosi...

Purpose. The etiology of neovascular age-related macular degeneration (nAMD) cannot be completely explained by identified environmental risk factors or single-locus gene variants. This study was to explore the potential interactions among gene variants on nAMD in Chinese population. Methods. 43 SNPs located in different genes were genotyped in 932 Chinese individuals (464 nAMD patients and 468 ...

Infiltrating macrophages are critically involved in pathogenic angiogenesis such as neovascular agerelated macular degeneration (nAMD). Macrophages originate from circulating monocytes and three subtypes of monocyte exist in humans: classical (CD14(+)CD16(-)), non-classical (CD14(-)CD16(+)) and intermediate (CD14(+)CD16(+)) monocytes. The aim of this study was to investigate the role of circula...

dynamics with NAMD on the IBM Blue Gene/L system S. Kumar C. Huang G. Zheng E. Bohm A. Bhatele J. C. Phillips H. Yu L. V. Kalé NAMD (nanoscale molecular dynamics) is a production molecular dynamics (MD) application for biomolecular simulations that include assemblages of proteins, cell membranes, and water molecules. In a biomolecular simulation, the problem size is fixed and a large number of ...

BACKGROUND Growth differentiation factor 6 (GDF6) has been reported to be a novel disease gene for age-related macular degeneration (AMD) in Caucasians. This study aimed to investigate whether rs6982567 was associated with neovascular AMD (nAMD) or polypoidal choroidal vasculopathy (PCV) in a Han Chinese cohort. METHODS A total of 612 participants (251 PCV patients, 157 nAMD patients and 204 ...

To examine the association of systemic, ocular and genetic risk factors in neovascular age-related macular degeneration (nAMD) in a large cohort of Asian patients, and to further compare risk factors between those with typical AMD and polypoidal choroidal vasculoapthy (PCV) subtypes. We recruited 456 cases and 1,824 controls matched for age, gender and ethnicity. Data on systemic and ocular ris...

PURPOSE To evaluate changes in the multifocal electroretinogram (mfERG) in patients with neovascular age-related macular degeneration (nAMD) undergoing ranibizumab treatment. METHODS This was an observational, longitudinal, prospective study. Treatment-naive patients with nAMD who met the inclusion and exclusion criteria underwent a course of monthly injections of ranibizumab over 3 months. A...

Cellular responses to hypoxia are mediated by the hypoxia-inducible factors (HIF). In normoxia, HIF-α proteins are regulated by a family of dioxygenases, through prolyl and asparagyl hydroxylation, culminating in proteasomal degradation and transcriptional inactivation. In hypoxia, the dioxygenases become inactive and allow formation of HIF transcription factor, responsible for upregulation of ...
