Age-related macular degeneration: choroidal ischaemia?
AIM Our aim is to use ultrasound to non-invasively detect differences in choroidal microarchitecture possibly related to ischaemia among normal eyes and those with wet and dry age-related macular degeneration (AMD). DESIGN Prospective case series of subjects with dry AMD, wet AMD and age-matched controls. METHODS Digitised 20 MHz B-scan radiofrequency ultrasound data of the region of the ma...
متن کاملVascular ischaemia and reperfusion injury.
Although restoration of blood flow to an ischaemic organ is essential to prevent irreversible tissue injury, reperfusion per se may result in a local and systemic inflammatory response that may augment tissue injury in excess of that produced by ischaemia alone. Cellular damage after reperfusion of previously viable ischaemic tissues is defined as ischaemia-reperfusion (I-R) injury. I-R injury ...
متن کاملChoroidal neovascularization in eyes with choroidal vascular hyperpermeability.
PURPOSE We describe the clinical and genetic characteristics of choroidal neovascularization (CNV) in eyes with choroidal vascular hyperpermeability (CVH). METHODS This cross-sectional study consisted of 438 consecutive patients who underwent fluorescein and indocyanine green angiography for macular disease. We used the genotypes of 1576 age-related macular degeneration (AMD) cases and 3248 g...
متن کاملIntravitreal Angiogenesis Inhibitors for Choroidal Vascular Conditions
Angiogenesis inhibitors (e.g., ranibizumab, bevacizumab, pegaptanib, aflibercept) are being evaluated for the treatment of disorders of choroidal circulation. Ophthalmic disorders affecting the choroidal circulation include age-related macular degeneration (AMD), central serous chorioretinopathy (CSC), pathologic myopia, presumed ocular histoplasmosis syndrome, angioid streaks, idiopathic choro...
متن کاملAssociation between choroidal morphology and anti-vascular endothelial growth factor treatment outcome in myopic choroidal neovascularization.
PURPOSE To investigate associations between outcome of anti-vascular endothelial growth factor (VEGF) therapy and choroidal morphology in eyes with myopic choroidal neovascularization (CNV). METHODS Fifty-two eyes of 46 patients with myopic CNV received a single intravitreal anti-VEGF injection, followed by as-needed injections. Baseline choroidal thickness was measured at the fovea and 1.5 a...
