Optical coherence tomography and autofluorescence findings in chronic phototoxic maculopathy secondary to snow-reflected solar radiation
A professional mountain trekker presented with gradual, moderate visual decline in one eye. The subnormal vision could not be explained by the examination of anterior and posterior segment of either eye, which was unremarkable. Optical coherence tomography and autofluorescence imaging revealed subtle defects in the outer retina, which correlated with the extent of visual disturbance. A novel pr...
متن کاملOuter Retinal Changes on Spectral-Domain Optical Coherence Tomography Pre- and Post-Silicone Oil Removal.
BACKGROUND AND OBJECTIVE To evaluate outer retinal changes present on spectral-domain optical coherence tomography (SD-OCT) in eyes pre- and post-silicone oil (SiO) removal (SOR). PATIENTS AND METHODS Retrospective case series of patients who underwent pars plana vitrectomy with SiO instillation and had SD-OCT completed pre- and post-SOR. SD-OCT parameters included presence of subretinal flui...
متن کاملOuter retinal tubulation: a novel optical coherence tomography finding.
OBJECTIVE To describe tubular structures found in the outer retina seen in a variety of retinal disorders. METHODS Sixty-nine eyes of 63 patients were examined with spectral-domain optical coherence tomography. Optical coherence tomography C-scans were correlated with their corresponding B-scans. The prevalence, number, size, and shape of the tubular structures were determined. RESULTS Bran...
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...
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 ...
