Evaluation of Optical Coherence Tomography Angiography Findings in Patients with Branch Retinal Vein Occlusion
Purpose: To analyze the correlation of optical coherence tomography angiography (OCTA) findings with visual acuity (VA) in patients with branch retinal vein occlusion (BRVO). Methods: This cross-sectional study was performed on 20 eyes of 20 patients with unilateral BRVO involving the macula referred to the ophthalmology clinic of Rassoul Akram Hospital. OCTA imaging was conducted for all patie...
متن کاملRetinal assessment using optical coherence tomography.
Over the 15 years since the original description, optical coherence tomography (OCT) has become one of the key diagnostic technologies in the ophthalmic subspecialty areas of retinal diseases and glaucoma. The reason for the widespread adoption of this technology originates from at least two properties of the OCT results: on the one hand, the results are accessible to the non-specialist where m...
متن کاملSpeckle Noise Reduction for the Enhancement of Retinal Layers in Optical Coherence Tomography Images
Introduction One of the most important pre-processing steps in optical coherence tomography (OCT) is reducing speckle noise, resulting from multiple scattering of tissues, which degrades the quality of OCT images. Materials and Methods The present study focused on speckle noise reduction and edge detection techniques. Statistical filters with different masks and noise variances were applied on ...
متن کاملNoninvasive, In Vivo Assessment of Mouse Retinal Structure Using Optical Coherence Tomography
BACKGROUND Optical coherence tomography (OCT) is a novel method of retinal in vivo imaging. In this study, we assessed the potential of OCT to yield histology-analogue sections in mouse models of retinal degeneration. METHODOLOGY/PRINCIPAL FINDINGS We achieved to adapt a commercial 3(rd) generation OCT system to obtain and quantify high-resolution morphological sections of the mouse retina wh...
متن کاملCorrelation between Visual Acuity and Optical Coherence Tomography-Measured Retinal Thickness in Diabetic Macular Edema
Background and Objective: Diabetic macular edema (DME) is one of the common complications of diabetes which significantly accounts for preventable visual impairment and blindness. Central macular thickness (CMT) is a feature found in DME patients. This study aims to determine the relationship between optical coherence tomography (OCT)-measured CMT and visual acuity (VA) in patients with DME bef...
