The histologic appearance of a consecutive series of 200 neovascular membranes was analyzed. Specific angiographic manifestations of exudative age-related macular degeneration such as classic or occult choroidal neovascularization, vascularized pigment epithelial detachment, tear of the retinal pigment epithelium, polypoidal choroidal vasculopathy and deep retinal vascular anomalous complex cor...

Macrophages are rapidly conditioned by cognate and soluble signals to acquire phenotypes that deliver specific functions during inflammation, wound healing and angiogenesis. Whether inhibitory CD200R signaling regulates pro-angiogenic macrophage phenotypes with the potential to suppress ocular neovascularization is unknown. CD200R-deficient bone marrow derived macrophages (BMMΦ) were used to de...

Diabetes is a common endocrine disorder associated with peripheral microvascular diseases such as proliferative retinal microangiopathy (or diabetic retinopathy), which may lead to blindness. Unfortunately, diabetic microvascular abnormalities in the choroid are underestimated in clinical practice. Recent literature has revealed that the severity of diabetic retinopathy is aggravated by choroid...

Tumors provide an extremely abnormal microenvironment that stimulates neovascularization from surrounding vessels and causes altered gene expression within vascular cells. Up-regulation of vascular endothelial growth factor (VEGF) receptors has allowed selective destruction of tumor vessels by administration of a chimeric protein consisting of VEGF121 coupled to the toxin gelonin (VEGF/rGel). W...

Pachychoroid neovasculopathy is a form of type 1 (subretinal pigment epithelium) neovascularization characterized by the involvement of dilated choroidal vessels in areas of increased choroidal thickness. This disease was originally described in three white female patients. Here we report the multimodal evaluation of a clinical case of PN in a white male patient.

PURPOSE To compare measurements of the foveolar choroidal blood circulation in subjects with nonexudative, age-related macular degeneration (AMD) with those of control subjects. METHODS Laser Doppler flowmetry was used to assess relative choroidal blood velocity (ChBVel), volume (ChBVol), and flow (ChBFlow) in the center of the fovea. Measurements were obtained in 20 eyes of 20 subjects with ...

PURPOSE To study the prevalence, tomographic features, and clinical characteristics of focal choroidal excavation (FCE) in eyes with exudative age-related macular degeneration (AMD). METHODS We examined 243 consecutive eyes with exudative AMD with a prototype swept-source optical coherence tomography (OCT) system. Three-dimensional images of the macular area, covering 6 × 6 mm(2), were recons...
