    2. 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 ...

    4. Comparison of Clinically Relevant Findings from High-Speed Fourier-Domain and Conventional Time-Domain Optical Coherence Tomography

      Purpose To compare the sensitivities of high-speed Fourier-domain optical coherence tomography (FD-OCT) and conventional time-domain (TD) OCT for the detection of clinical findings important in the management of common vitreoretinal disorders. Design Prospective, observational study. Methods FD-OCT scans (128 B scans 512 A scans) were obtained using a prototype instrument (3 D-OCT; Topcon, Tokyo, Japan) in 50 eyes of 28 consecutive patients undergoing conventional high-resolution (6 B scans 512 A ...

    5. Signal Strength is an Important Determinant of Accuracy of Nerve Fiber Layer Thickness Measurement by Optical Coherence Tomography.

      Purpose: To investigate the effect of signal strength on the measurement of the retinal nerve fiber layer (RNFL) using optical coherence tomography (OCT). Methods: Eyes with known or suspected glaucoma or nonglaucomatous optic atrophy were scanned twice within the same visit using Stratus OCT's Fast Nerve Fiber Layer Thickness protocol. Only those eyes with 2 high-quality scans (signal strengths of at least 5 and different from each other, no ...

    6. Association Of The Extent Of Diabetic Macular Edema As Assessed By Optical Coherence Tomography With Visual Acuity And Retinal Outcome Variables.

      Purpose: To determine whether the extensiveness of diabetic macular edema using a 10-step scale based on optical coherence tomography explains pretreatment variation in visual acuity and predicts change in macular thickness or visual acuity after laser photocoagulation. Methods: Three hundred twenty-three eyes from a randomized clinical trial of two methods of laser photocoagulation for diabetic macular edema were studied. Baseline number of thickened optical coherence tomography subfields was used to ...

    10. Quantitative Optical Coherence Tomography Findings in Various Subtypes of Neovascular Age-Related Macular Degeneration

      PURPOSE. To compare the volume of various spaces visible on optical coherence tomography (OCT) images in different angiographic lesion subtypes of neovascular age-related macular degeneration (AMD). METHODS. Sixty-six cases of previously untreated, active subfoveal choroidal neovascularization (CNV) associated with AMD were retrospectively collected. CNV lesions were classified as occult with no classic CNV, minimally classic CNV, predominantly classic CNV, or CNV lesions with associated retinal angiomatous proliferation (RAP). Corresponding OCT ...

      Purpose To investigate the relationship between optical coherence tomography (OCT)-derived measurements of retinal morphology and visual acuity in patients with neovascular age-related macular degeneration (AMD). Design Retrospective cross-sectional study. Participants A total of 216 consecutive patients (216 eyes) newly diagnosed with neovascular AMD who underwent StratusOCT imaging at the time of diagnosis. Methods Best-corrected Snellen visual acuity was recorded for each patient. Raw exported StratusOCT images for each patient ...

    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.
