      Stabilized retinal imaging with adaptive optics
      A system provides an optical image of an object. A first module tracks a reference feature of the object. A second module includes a source for an imaging beam, a scanning device to move the imaging beam along a portion of the object and a detection device receives a signal associated with an image of the portion of the object. The first module controls the position of the imaging beam relative to the reference feature to correct for the motion of the object. A third module detects a distortion of the object and compensates for the distortion.

    2. Real-time processing for Fourier domain optical coherence tomography using a field programmable gate array

      Teoman E. Ustun, Nicusor V. Iftimia, R. Daniel Ferguson, and Daniel X. Hammer Real-time display of processed Fourier domain optical coherence tomography (FDOCT) images is important for applications that require instant feedback of image information, for example, systems developed for rapid screening or image-guided surgery. However, the computational requirements for high-spe ... [Rev. Sci. Instrum. 79, 114301 (2008)] published Mon Nov 3, 2008.

    3. Foveal Fine Structure in Retinopathy of Prematurity: An Adaptive Optics Fourier Domain Optical Coherence Tomography Study

      purpose. To describe the fine structure of the fovea in subjects with a history of mild retinopathy of prematurity (ROP) using adaptive optics–Fourier domain optical coherence tomography (AO-FDOCT). methods. High-speed, high-resolution AO-FDOCT videos were recorded in subjects with a history of ROP (n = 5; age range, 14–26 years) and in control subjects (n = 5; age range, 18–25 years). Custom software was used to extract foveal pit depth and volume from three-dimensional (3-D) retinal maps. The thickness of retinal layers as a function of retinal eccentricity was measured manually. The retinal vasculature in the parafoveal region was assessed ...
