    1. Relationship between angiographic and optical coherence tomographic (OCT) parameters for quantifying choroidal neovascular lesions

      Explore SpringerLink Home Ophthalmology

      Background To correlate the volume of various spaces on optical coherence tomography (OCT) with fluorescein angiographic (FA) parameters in neovascular age-related macular degeneration (AMD). Methods Sixty-five consecutive cases of active subfoveal choroidal neovascularization (CNV) associated with AMD were retrospectively collected. Area and greatest linear dimension of CNV lesion components were calculated on FA. Corresponding StratusOCT image sets were analyzed using custom software (termed OCTOR), which allows manual measurement of the volume of the neurosensory retina, subretinal fluid, subretinal tissue, and pigment epithelial detachment (PED). Results Area of occult CNV on FA correlated with PED (R = 0.62) and subretinal fluid ...

      Aim: To compare the retinal morphologic characteristics of eyes with choroidal neovascularization (CNV) secondary to pathologic myopia versus eyes with CNV secondary to age-related macular degeneration (AMD), using quantitative optical coherence tomography (OCT) subanalysis.Methods: Twenty-one eyes of 21 patients newly diagnosed with CNV secondary to pathologic myopia, and 43 consecutive cases of eyes with newly diagnosed subfoveal CNV secondary to AMD were retrospectively collected. In all patients, StratusOCT images and fluorescein angiograms (FA) were available for analysis. StratusOCT images were analyzed using custom software (termed "OCTOR"), which allowed calculation of the thickness/volume of the neurosensory retina, subretinal fluid ...

    3. Quantitative Subanalysis of Optical Coherence Tomography after Treatment with Ranibizumab for Neovascular Age-Related Macular Degeneration

      PURPOSE. To investigate the effects of ranibizumab on retinal morphology in patients with neovascular age-related macular degeneration (AMD) using optical coherence tomography (OCT) quantitative subanalysis. METHODS. Data from 95 patients receiving intravitreal ranibizumab for neovascular AMD were collected. StratusOCT images were analyzed using custom software that allows precise positioning of prespecified boundaries on every B-scan. Changes in thickness/volume of the retina, subretinal fluid (SRF), subretinal tissue (SRT), and pigment epithelial detachments (PEDs) at week 1 and at months 1, 3, 6, and 9 after treatment were calculated. RESULTS. Total retinal volume reached its nadir at month 1, with an ...
