Although neovascular (wet) age-related macular degeneration (AMD) only accounts for 10-20% of all AMD, the majority (about 90%) of severe vision loss associated with AMD is due to this form. Results from recent studies have implied that vascular endothelial growth factor (VEGF), particularly VEGF(165), plays a predominant role in the development of ocular neovascularization and vascular leakage...

Anti-VEGF-A therapy has proven to be effective for many neovascular diseases. However, drug resistance to anti-VEGF-A treatment can develop. Also, not all patients with neovascular diseases are responsive to anti-VEGF-A treatment. The mechanisms underlying these important issues remain unclear. In this study, using different model systems, we found that inhibition of VEGF-A directly upregulated...

We assessed the feasibility of transplanting a sheet of retinal pigment epithelial (RPE) cells differentiated from induced pluripotent stem cells (iPSCs) in a patient with neovascular age-related macular degeneration. The iPSCs were generated from skin fibroblasts obtained from two patients with advanced neovascular age-related macular degeneration and were differentiated into RPE cells. The RP...

Purpose. Cyclectomy/trabeculectomy and Ahmed glaucoma valve implant are operations suggested for refractory glaucomas. In this study, we have evaluated the outcomes that we observed with these two techniques in neovascular glaucoma patients. Material and Methods. Thirty-five eyes with neovascular glaucomas were included in this study. Ahmed Glaucoma valve (group A) was applied to ten eyes, whil...

We report seven cases of subretinal neovascularisation with inferior posterior staphyloma. The upper border of the shallow staphyloma, detected by B-mode echography, invaded the macular area, and there was a neovascular net at the edge of the staphyloma. Three of the cases showed chorioretinal atrophy at the upper edge of the staphyloma in the same location as the neovascular net. Our cases wer...

The purpose of this study was to describe the surgical outcomes and safety of intracameral bevacizumab during trabeculectomy in eyes with neovascular glaucoma. Pilot study included four eyes (four patients) with refractory neovascular glaucoma submitted to fornix-based trabeculectomy with adjunctive use of bevacizumab in the anterior chamber during the procedure. Patients were previously treate...

PURPOSE Age-related macular degeneration (AMD) is a multifactorial disease involving genetic and environmental factors. Most of the genetic factors identified so far involve the nuclear genome. Recently, two studies in North America and Australia reported an association between advanced AMD and the mitochondrial T2 haplogroup. Our purpose was to assess this association in a large French populat...

Baicalin is a flavonoid derived from the dried root of Scutellaria baicalensis. In this study, oxygen-induced retinopathy was used to characterize the anti-angiogenic properties of baicalin in mice. Pups were exposed to a hyperbaric oxygen environment to induce retinal angiogenesis and were subjected to intraperitoneal injection of baicalin. Avascular area, neovascular tufts, and neovascular lu...

OBJECTIVES To assess durability of visual and anatomic gains with 2.0 mg ranibizumab in recalcitrant neovascular age-related macular degeneration (AMD). METHODS Phase I-II trial of 88 patients with recalcitrant neovascular AMD treated as needed every 4 (cohort A) or 6 weeks (cohort B) following three monthly doses. ETDRS refraction and spectral-domain OCT-guided as-needed re-treatments. RES...

While anti-vascular endothelial growth factor (VEGF) therapy affords patients with neovascular age-related macular degeneration (AMD) a dramatically improved prognosis compared to all prior treatments, the chronic nature of the disease and the uncertainties regarding long-term dosing strategies represent important therapeutic challenges. Large randomized trials established the efficacy and safe...
