Evaluation of Retinal Changes Using Optical Coherence Tomography in a Pediatric Case of Susac Syndrome
Susac syndrome is a rare occlusive vasculopathy affecting the retina, inner ear and brain. The cause is unknown, although it generally affects young women. This syndrome can be difficult to diagnose because its signs can only be revealed by detailed examination. These signs are not always concomitant, but may appear at different times. This report describes a pediatric case who was diagnosed wi...
متن کاملEvaluation 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 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 کاملRetinal vasculitis in Susac syndrome: case report.
A 29 year old male was admitted at the emergency room suffering from gradually worsening headache followed by nausea. In the hospital patient presented with lethargy, reduction of consciousness level and bilateral hypoacusis. Ophthalmic examination and fluorescein angiography showed retinal vasculitis. This finding was crucial to the diagnosis of Susac syndrome, a rare disease characterized by ...
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...
