    1. VALUE OF FRACTAL ANALYSIS OF OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IN VARIOUS STAGES OF DIABETIC RETINOPATHY

      VALUE OF FRACTAL ANALYSIS OF OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IN VARIOUS STAGES OF DIABETIC RETINOPATHY

      Purpose: To use fractal dimensional analysis to investigate retinal vascular disease patterns in patients with diabetic retinopathy using spectral domain optical coherence tomography angiography. Methods: A retrospective study was conducted which included 49 eyes from 26 control subjects and 58 eyes from 35 patients known to have diabetic retinopathy. Of the 58 eyes with known retinopathy, 31 were categorized as nonproliferative diabetic retinopathy (13 mild, 9 moderate, and 9 severe) and 27 were categorized as proliferative diabetic retinopathy. Optical coherence tomography angiography images were acquired using the RTVue XR Avanti (Optovue, Inc). Automated segmentation was obtained through both the superficial ...

    2. Correlation between Fluorescein Angiography and Spectral Domain Optical Coherence Tomography in the Diagnosis of Cystoid Macular Edema

      Aims: To compare the ability to detect cystoid macular edema (CME) and its late complications between Spectral Domain Optical Coherence Tomography (SD-OCT) and Fluorescein Angiography (FA). Methods: Retrospective, observational, case series. 85 eyes who had FA and SD-OCT performed on the same day at first visit and/or at follow-up visits were included. FA and SD-OCT images were evaluated for the evidences associated with CME and other structural changes of macula. FA and SD-OCT images were then superimposed to determine the relationships of diagnostic features between the two images. Main outcome measure was the correlation between FA and SD-OCT findings ...

    3. Correlation between Spectral Domain Optical Coherence Tomography Findings and Fluorescein Angiography Patterns in Diabetic Macular Edema

      Objective: To study the relationship between spectral domain optical coherence tomography (SD-OCT) findings and fluorescein angiography (FA) patterns in patients with diabetic macular edema (DME). Design: Retrospective, observational, cross-sectional study. Participants: We included 59 eyes from 59 patients with DME that had SD-OCT/scanning laser ophthalmoscope (SLO) and FA performed on the same day. Eyes with macular edema owing to other ocular diseases were excluded. Methods: The relationship between SD-OCT and FA findings was evaluated by superimposing and aligning the SLO images onto the FA photos. The SLO image of the OPKO/OTI Spectral OCT/SLO (OPKO-OTI, Miami, FL) corresponds ...

    4. Multidimensional en-Face OCT imaging of the retina

      Multidimensional en-Face OCT imaging of the retina
      Fast T-scanning (transverse scanning, en-face) was used to build B-scan or C-scan optical coherence tomography (OCT) images of the retina. Several unique signature patterns of en-face (coronal) are reviewed in conjunction with associated confocal images of the fundus and B-scan OCT images. ... [Opt. Express 17, 4112-4133 (2009)]

    5. Imaging Vitreo-Macular Interface Abnormalities In The Coronal Plane By Simultaneous Combined Scanning Laser And Optical Coherence Tomography

      Purpose: To describe vitreo-retinal imaging of eyes with vitreo-macular abnormalities using high-resolution coronal-plane optical coherence tomography (OCT) scanning combined with simultaneous scanning laser ophthalmoscope (SLO) imaging. Methods: A SLO-OCT (OTI, Canada) was used to scan patients with vitreo-macular interface abnormalities including epiretinal membranes, macular hole, incomplete posterior vitreous detachment, vitreo-macular traction syndromes and diabetic and cystoid macular edema. The longitudinal –B scan images and the transverse –C scan images in the coronal plane were used to describe vitreo-macular interface abnormalities. The SLO-OCT simultaneously produces a confocal image of the retina. Results: The longitudinal ‘B’ scan and en-face ‘C’ scan images ...

    6. Macular Holes and Macular Pucker: The Role of Vitreoschsis as Imaged By Optical Coherence Tomography/Scanning Laser Ophthalmoscopy

      Macular Holes and Macular Pucker: The Role of  Vitreoschsis as Imaged By Optical Coherence Tomography/Scanning Laser Ophthalmoscopy
      Purpose The pathogenesis of macular pucker and macular holes is poorly understood. Anomalous posterior vitreous detachment (PVD) and vitreoschisis have been proposed as possible mechanisms. This study used clinical imaging to seek vitreoschisis and study the topographic features of macular pucker and macular holes. Methods Combined optical coherence tomography and scanning laser ophthalmoscopy (OCT/SLO) was performed in 45 eyes with macular hole and 44 eyes with macular pucker. Longitudinal imaging was used to identify vitreoschisis and measure retinal thickness. The topographic features of eyes with macular hole with eccentric macular contraction were compared to 24 eyes with unifocal macular ...
