    3. Different Concentrations of Aqueous Cytokines According to Diabetic Macular Edema Patterns as Determined Optical Coherence Tomography

      Different Concentrations of Aqueous Cytokines According to Diabetic Macular Edema Patterns as Determined Optical Coherence Tomography

      Objective: To evaluate the relationship between various cytokine levels in aqueous humor and diabetic macular edema (DME) types as determined by optical coherence tomographic (OCT) patterns. Methods: The study examined 76 patients with DME at early phase. Ten patients who underwent cataract surgery served as controls. Eyes with DME were divided into four groups, based on OCT patterns of DME, prior to intravitreal bevacizumab injection (IVB). Patterns included sponge-like diffuse retinal thickening (SDRT) (n=27), cystoid macular edema (CME) (n=18), serous retinal detachment (SRD) (n=15), and combined CME and SRD (n=16). Visual acuity, central macular thickness (CMT ...

    9. Angle closure glaucoma detection using fractal dimension index on SS-OCT images

      Angle closure glaucoma detection using fractal dimension index on SS-OCT images

      Optical coherence tomography (OCT) is a high resolution, rapid and non-invasive screening tool for angle closure glaucoma. In this paper, we propose a new strategy for automatic and landmark invariant quantification of the anterior chamber angle of the eye using swept source optical coherence tomography (SS-OCT) images. Seven hundred and eight swept source optical coherence tomography SS-OCT images from 148 patients with average age of (59.48 ± 8.97) were analyzed in this study. The angle structure is measured by fractal dimension (FD) analysis to quantify the complexity or changes of angle recess. We evaluated the FD index with biometric ...
