    4. Optical Coherence Tomography Angiography of Two Choroidal Nevi Variants

      Optical Coherence Tomography Angiography of Two Choroidal Nevi Variants
      Optical coherence tomography angiography (OCT-A) is a recently established noninvasive technology for evaluation of the retinal and choroidal vasculature. The literature regarding the findings in choroidal nevi is scarce. We report the OCT-A findings associated with two different variants. Subject one had decreased vascular flow signal in the choroidal, choriocapillaris, deep retinal, and superficial retinal layers. Subject two had decreased vascular flow signal in the choroidal, choriocapillaris, and deep retinal ...

    5. Improving lateral resolution and image quality of optical coherence tomography by the multi-frame superresolution technique for 3D tissue imaging

      Improving lateral resolution and image quality of optical coherence tomography by the multi-frame superresolution technique for 3D tissue imaging
      The multi-frame superresolution technique is introduced to significantly improve the lateral resolution and image quality of spectral domain optical coherence tomography (SD-OCT). Using several sets of low resolution C-scan 3D images with lateral sub-spot-spacing shifts on different sets, the multi-frame superresolution processing of these sets at each depth layer reconstructs a higher resolution and quality lateral image. Layer by layer processing yields an overall high lateral resolution and quality 3D ...

    6. Differences in OCT Assessment of Bruch Membrane Opening Compared to Stereoscopic Photography for Estimating Cup-to-Disc Ratio

      Differences in OCT Assessment of Bruch Membrane Opening Compared to Stereoscopic Photography for Estimating Cup-to-Disc Ratio
      Purpose To compare the vertical and horizontal cup-to-disc ratio (VCDR, HCDR) by an updated optical coherence tomography (OCT) Bruchs membrane opening (BMO) algorithm and stereoscopic optic disc photograph readings by glaucoma specialists. Design Reliability analysis. Methods 195 eyes (116 glaucoma and 79 glaucoma suspects) of 99 patients with stereoscopic photos and OCT scans of the optic discs taken during the same visit were compared. Optic disc photos were read by ...

    7. Optical coherence tomography angiography: A comprehensive review of current methods and clinical applications

      Optical coherence tomography angiography: A comprehensive review of current methods and clinical applications
      OCT has revolutionized the practice of ophthalmology over the past 1020 years. Advances in OCT technology have allowed for the creation of novel OCT-based methods. OCT-Angiography (OCTA) is one such method that has rapidly gained clinical acceptance since it was approved by the FDA in late 2016. OCTA images are based on the variable backscattering of light from the vascular and neurosensory tissue in the retina. Since the intensity and ...

    8. Combination of anterior segment optical coherence tomography modalities to improve accuracy of rectus muscle insertion location - ScienceDirect

      Combination of anterior segment optical coherence tomography modalities to improve accuracy of rectus muscle insertion location - ScienceDirect
      Anterior segment optical coherence tomography (AS-OCT) is useful for locating the extraocular muscle insertion prior to strabismus surgery; however, its accuracy decreases in reoperations. This masked retrospective study investigated whether a combination of AS-OCT modalities improves accuracy. The distance between the corneoscleral limbus and extraocular muscle insertion was measured with AS-OCT, first using the standard grayscale modality alone and then refined with the color modality. The AS-OCT measurement was considered ...

    9. Characterization of Soft Contact Lens Fitting Using Ultra-Long Scan Depth Optical Coherence Tomography

      Characterization of Soft Contact Lens Fitting Using Ultra-Long Scan Depth Optical Coherence Tomography
      Objectives . To evaluate the centration and movement of soft contact lenses and to verify the repeatability of two repeated measurements of the lens centration and movement using ultra-long scan depth optical coherence tomography (UL-OCT). Methods . A 1-day Acuvue Define lens was tested on both eyes of 10 subjects (5 males and 5 females; mean age, 31.6 years). The centration and blink-induced movement of the contact lens were measured using ...

    10. Multimodal images of chronic branch retinal vein occlusion

      Multimodal images of chronic branch retinal vein occlusion
      Two illustrative cases of chronic branch retinal vein occlusion are presented with multimodal imaging, including commercially available optical coherence tomography angiography. In these two patients, retinal ischemia and collateral vessels were well imaged without the need to use traditional fluorescein angiography. Optical coherence tomography angiography provides useful information for the diagnosis and management of patients with branch retinal vein occlusion and other retinal vascular diseases.

    11. The application of optical coherence tomography angiography in uveitis and inflammatory eye diseases

      The application of optical coherence tomography angiography in uveitis and inflammatory eye diseases
      Since its introduction in the early 1990s, optical coherence tomography (OCT) has evolved in resolution and technological advances, and in recent years its initial application of assessing the morphology of a tissue has been implemented by the study of its functional blood flow, through optical coherence tomography angiography (OCTA). This novel technique details capillary networks by comparing the amount of light returned from static and moving targets without the need ...

    12. Role of high resolution optical coherence tomography in diagnosing ocular surface squamous neoplasia with coexisting ocular surface diseases

      Role of high resolution optical coherence tomography in diagnosing ocular surface squamous neoplasia with coexisting ocular surface diseases
      Purpose Coexistence of an ocular surface disease can mask the typical features of ocular surface squamous neoplasia (OSSN). The purpose of this study was to evaluate high resolution optical coherence tomography (HR-OCT) as an adjunct in the detection and differentiation of OSSN within coexisting ocular surface pathologies. Methods Retrospective study of 16 patients with ocular surface disease and lesions suspicious for OSSN that were evaluated with HR-OCT. HR-OCT images of ...

      Reflectometry and Optical Coherence Tomography for Non-invasive High Resolution Tear Film Thickness Evaluation and Ophthalmic Imaging (Thesis)
      Dry eye debilitates the patients physically, limit their ability to perform daily tasks, cause clinical depression, and compromise quality of life. Accurate diagnosis of the dry eye and the research on the pathological mechanism and treatment both depend largely on the available measurement techniques. The development of new measurement techniques helps better understanding of the disease and paves the way for accurate early diagnosis and better treatment. The purpose of ...
