Optical coherence tomographic characteristics of microaneurysms in diabetic retinopathy.
PURPOSE To characterize microaneurysms in diabetic retinopathy (DR) depicted by spectral-domain optical coherence tomography (SD-OCT). DESIGN Retrospective, observational case series. METHODS We surveyed a consecutive series of 76 eyes from 60 patients with DR (22 mild nonproliferative diabetic retinopathy [NPDR]; 43 moderate NPDR; 9 severe NPDR; 2 proliferative diabetic retinopathy [PDR]) ...
متن کاملNoninvasive detection of microaneurysms in diabetic retinopathy by swept-source optical coherence tomography
BACKGROUND AND OBJECTIVES A method of identifying retinal vascular microaneurysms (MAs) in nonproliferative diabetic retinopathy (NPDR) using swept-source optical coherence tomography (SS-OCT). PATIENTS AND METHODS SS-OCT images were acquired in 17 eyes with NPDR using prototype SS-OCT device and fluorescein angiography (FA) images were obtained simultaneously. MAs identified on SS-OCT slabs ...
متن کاملCorrelation of leaking microaneurysms with retinal thickening in diabetic retinopathy.
AIM To investigate the contribution of fluorescein angiographic leaking microaneurysms (leak-MA) versus non-leaking microaneurysms (non-leak-MA) to retinal thickening in diabetic retinopathy. METHODS A consecutive series of 38 eyes from 24 patients with diabetic retinopathy was included. Leak-MA and non-leak-MA in each eye were selected in pairs at corresponding topographic location. Leaking ...
متن کاملSubnanometer optical coherence tomographic vibrography.
The ability to quantify and visualize submicrometer-scale oscillatory motions of objects in three dimensions has a wide range of application in acoustics, materials sciences, and medical imaging. Here we demonstrate that volumetric snapshots of rapid periodic motion can be captured using optical coherence tomography (OCT) with subnanometer-scale motion sensitivity and microsecond-scale temporal...
متن کاملOptical Coherence Tomographic Findings in Berlin’s Edema
PURPOSE To describe optical coherence tomography (OCT) findings in a patient with Berlin's edema following blunt ocular trauma. CASE REPORT A 26-year-old man presented with acute loss of vision in his left eye following blunt trauma. He underwent a complete ophthalmologic examination and OCT. Fundus examination revealed abnormal yellow discoloration in the macula. OCT disclosed thickening of ...
