    1. Evaluation of changes in choroidal vascularity during acute anterior uveitis attack in patients with ankylosing spondylitis by using binarization of EDI-optical coherence tomography images

      Evaluation of changes in choroidal vascularity during acute anterior uveitis attack in patients with ankylosing spondylitis by using binarization of EDI-optical coherence tomography images

      Background To evaluate the effect of the first acute anterior uveitis (AAU) attack on the choroid by using an image binarization tool on images from enhanced depth imaging (EDI)-optical coherence tomography (OCT) scans in patients with ankylosing spondylitis (AS). Methods In this study, three groups were formed: uveitic eyes (UE; n = 20) of patients with AS, the non-uveitic eyes (NUE; n = 20) of these patients, and the eyes of healthy controls (n = 20). EDI-OCT images were obtained during the first AAU attack and at three months after treatment in patients with AS. An image binarization tool (ImageJ software; Bethesda ...

    2. Choroidal vascularity index determined by binarization of enhanced depth imaging optical coherence tomography images in eyes with intermediate age-related macular degeneration

      Choroidal vascularity index determined by binarization of enhanced depth imaging optical coherence tomography images in eyes with intermediate age-related macular degeneration

      Purpose To evaluate choroidal structural changes in patients with intermediate age-related macular degeneration using choroidal vascularity index. Methods The eyes of patients with intermediate age-related macular degeneration and controls were evaluated with enhanced depth imaging optical coherence tomography images. Subfoveal choroidal area was segmented into luminal area and stromal area by the binarization technique on enhanced depth imaging optical coherence tomography images using ImageJ software. Choroidal vascularity index was defined as the ratio of luminal area to total circumscribed subfoveal choroidal area. Results Fifty-seven eyes with intermediate age-related macular degeneration and 60 healthy control eyes were included in the study ...

    3. Effect of Optical Coherence Tomography Patterns on One-year Outcomes of Aflibercept Therapy for Diabetic Macular Edema

      Effect of Optical Coherence Tomography Patterns on One-year Outcomes of Aflibercept Therapy for Diabetic Macular Edema

      Objective: To evaluate the outcomes of aflibercept based on different morphologic patterns on optical coherence tomography (OCT) for diabetic macular edema (DME). Study Design: Observational study. Place and Duration of Study: Beyoglu Eye Training and Research Hospital, Turkey from February 2016 to March 2018. Methodology: Records of 115 eyes of 115 patients who were treated with aflibercept for DME were reviewed. Eyes were classified based on OCT features as diffuse retinal thickening (DRT, n=37), cystoid macular edema (CME, n=40), and serous retinal detachment (SRD, n=38). Best-corrected visual acuity (BCVA) and central subfield retinal thickness (CST) at baseline ...

    4. Neurodegeneration in ocular and central nervous systems: optical coherence tomography study in normal-tension glaucoma and Alzheimer disease

      Neurodegeneration in ocular and central nervous systems: optical coherence tomography study in normal-tension glaucoma and Alzheimer disease

      Background/aim: To evaluate, in vivo, the optical coherence tomography (OCT) of the retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC) in patients with normal-tension glaucoma (NTG) and those with Alzheimer disease (AD) in comparison with healthy subjects. Materials and methods: This cross-sectional study included 18 patients with NTG, 20 with AD, and 20 control subjects. An ophthalmologic examination and OCT scans of both eyes were performed in all patients. Results: There was a significant reduction in peripapillary RNFL thickness and macular GCC thickness and a significant increase in the global loss volume (GLV) rate in both the ...
