Choroidal neovascularisation (CNV) in the context of exsudative age-related macular degeneration (nAMD) can be divided into type 1 (occult) and type 2 (classical) membranes. Retinal angiomatous proliferation (RAP) or polypoidal choroidal vasculopathy (PCV) are "rare subtypes" of chorioretinal neovascularisation and are distinguished by their distinct morphology and the sometimes worse response to therapy. Chorioretinal anastomosis, severe exsudates with serosanguinous pigment epithelial detachment and, in PCV, orange-red lesions in the papillomacular bundle can be diagnostic...

Retinitis Pigmentosa (RP) has been reported to be associated with retinal hemangioma, retinal angiomatous proliferation, polypoidal choroidal vasculopathy and vasoproliferative tumours. However there is no previous report of choroidal nevus in an eye with RP. We describe such a case in which the eye with RP had a choroidal nevus at the macula. The coexistence of these two entities in the same eye emphasizes the need of careful examination of patients with RP. The presence of choroidal nevus warrants additional investigations such as B scan ultrasonography and a close follow-up to pick up changes in the nevus size and morphology...

Pathological neovascularization, a leading cause of blindness, is seen in retinopathy of prematurity, diabetic retinopathy, and age-related macular degeneration. Using a mouse model of hypoxia-driven retinal neovascularization, we find that fibroblast growth factor 21 (FGF21) administration suppresses, and FGF21 deficiency worsens, retinal neovessel growth. The protective effect of FGF21 against neovessel growth was abolished in adiponectin (APN)-deficient mice. FGF21 administration also decreased neovascular lesions in two models of neovascular age-related macular degeneration: very-low-density lipoprotein-receptor-deficient mice with retinal angiomatous proliferation and laser-induced choroidal neovascularization...

PURPOSE: To determine the incidence and clinical characteristics of angiographic subtypes of polypoidal choroidal vasculopathy (PCV). METHODS: It is a prospective, multicenter, cross-sectional study. Patients with newly diagnosed exudative macular degeneration are classified into PCV, age-related macular degeneration (AMD), and retinal angiomatous proliferation. Polypoidal choroidal vasculopathy is further classified into two subtypes depending on the presence (Type 1: polypoidal choroidal neovascularization) or absence (Type 2: typical PCV) of feeder vessels on indocyanine green angiography...

PURPOSE: To identify signs occurring more frequently in retinal angiomatous proliferation (RAP) lesions compared with other types of choroidal neovascularization (CNV) in age-related macular degeneration. METHODS: In this cross-sectional retrospective study, 30 patients were evaluated. These signs were correlated with the type of CNV: shunting of blood flow to the lesion by fluorescein angiography, late leakage by indocyanine green angiography, intraretinal cysts and retinal pigmented epithelium interruption along the retinal pigmented epithelium detachment with a hyperreflective oval area by spectral domain optical coherence tomography, and presence of reticular pseudodrusen by infrared light...

BACKGROUND: Retinal angiomatous proliferations (RAP) are a subgroup of exsudative or "wet" age-related macular degeneration (wAMD) with devastating reduction of visual acuity in later stages. Intravitreal ranibizumab provides good therapy, but is considered to be less effective than in other choroidal neovascularizations (CNV). OBJECTIVE: We investigated the efficacy of ranibizumab in late-stage III RAP with retinochoroidal anastomosis compared to the outcome of other CNV lesions...

We present a multi-functional optical coherence tomography (OCT) imaging approach to study retinal changes in the very-low-density-lipoprotein-receptor (VLDLR) knockout mouse model with a threefold contrast. In the retinas of VLDLR knockout mice spontaneous retinal-chorodoidal neovascularizations form, having an appearance similar to choroidal and retinal neovascularizations (CNV and RNV) in neovascular age-related macular degeneration (AMD) or retinal angiomatous proliferation (RAP). For this longitudinal study, the mice were imaged every 4 to 6 weeks starting with an age of 4 weeks and following up to the age of 11 months...

AMD is a major cause of blindness in the elderly. Previous sequencing studies of AMD susceptibility genes have revealed the association of rare coding variants in CFH, CFI, C3 and C9 in European population; however, the impact of rare or low-frequency coding variants on AMD susceptibility in other populations is largely unknown. To identify the role of low-frequency coding variants on exudative AMD susceptibility in a Japanese population, we analyzed the association of coding variants of 34 AMD candidate genes in the two-stage design by a multiplex PCR-based target sequencing method...

OBJECTIVE: To present the clinical relevance of the anatomical classification of the neovascular form of Age-Related Macular Degeneration (AMD). METHODS: Critical analysis of the current situation in the management of patients with neovascular AMD, by reviewing the available scientific evidence with regards to the classification of the types of neovascular lesion by angiography and optical coherence tomography (OCT). RESULTS: The classification of the neovascular lesion type secondary to AMD by OCT in type 1 lesions (under the pigment epithelium), type 2 (subretinal), and type 3 (retinal angiomatous proliferation), provides an added value in allowing to establish a long-term visual prognosis, an estimate of the number of treatments that a certain case may require, and a stratification of the risk for secondary geographic atrophy...
