    7. Imaging chorioretinal vascular disease

      Since its first description more than 40 years ago, fluorescein angiography had a crucial role in the diagnosis and management of chorioretinal vascular disorders such as neovascular age-related macular degeneration. Although fluorescein angiography permits visualization of the retinal microcirculation in exquisite detail, visualization of the choroidal circulation is more limited. Moreover, fluorescein angiography provides only minimal information regarding the functional consequences of vascular disease and allows, at best, only semi-quantitative ...

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

      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 ...

    11. Macular Thickness Measurements in Normal Eyes With Time-Domain and Fourier-Domain Optical Coherence Tomography

      Purpose: To compare macular thickness measurements using time-domain optical coherence tomography (OCT) and Fourier-domain OCT. Methods: Thirty-two eyes from 32 normal patients underwent complete ophthalmic evaluation. Macular scanning using the StratusOCT and the RTVue-100 OCT were performed for a total of three times each on the same visit. The average retinal thicknesses of the nine macular sectors as defined by the Early Treatment Diabetic Retinopathy Study, along with the foveal ...

    12. Accuracy of Retinal Thickness Measurements obtained with Cirrus Optical Coherence Tomography

      Aim: To report the frequency and severity of retinal thickness measurement errors in a Fourier domain optical coherence tomography (FDOCT) device, Cirrus OCT. Methods: Data from 209 eyes undergoing Cirrus OCT imaging with the Macular Cube protocol were collected. For each eye, the position of the automated retinal boundary lines used by the Cirrus OCT software for thickness calculations was assessed using a 6-point categorical scale. The presence of errors ...

    1. With CIRRUS FastTrac, I can place a highest resolution 20x B-Scan precisely on the area I am treating at each successive visit to see the fine details of the patient’s response to treatment...It’s also very helpful for removing any eye motion from the larger cube scans without disturbing my patient flow because it works so quickly. My initial experience is that FastTrac is about 30 percent faster than other tracking methods I have used.
