The clinical spectrum of microcystic macular edema.
PURPOSE Microcystic macular edema (MME), originally described in British literature as microcystic macular oedema (MMO), defines microcysts in the inner nuclear layer (INL) of the retina. Microcystic macular edema was described in multiple sclerosis (MS), but can be found in numerous disorders. The presence of MME has important prognostic and therapeutic implications; however, the differential ...
متن کاملSimultaneous segmentation of retinal surfaces and microcystic macular edema in SDOCT volumes
Optical coherence tomography (OCT) is a noninvasive imaging modality that has begun to find widespread use in retinal imaging for the detection of a variety of ocular diseases. In addition to structural changes in the form of altered retinal layer thicknesses, pathological conditions may also cause the formation of edema within the retina. In multiple sclerosis, for instance, the nerve fiber an...
متن کاملOCT Classification of Clinically Significant Macular Edema
Diabetic macular edema is the commonest cause of visual loss in patients with non proliferative diabetic retinopathy and a common cause of visual loss in PDR. According to Early Treatment Diabetic Retinopathy study, early detection and laser treatment of clinically significant macular oedema decreases the risk of moderate visual loss by 50%. Though laser has been the standard of care till recen...
متن کاملDevelopment of a Semi-Automatic Segmentation Method for Retinal OCT Images Tested in Patients with Diabetic Macular Edema
PURPOSE To develop EdgeSelect, a semi-automatic method for the segmentation of retinal layers in spectral domain optical coherence tomography images, and to compare the segmentation results with a manual method. METHODS SD-OCT (Heidelberg Spectralis) scans of 28 eyes (24 patients with diabetic macular edema and 4 normal subjects) were imported into a customized MATLAB application, and were ma...
متن کاملDiabetic macular edema: an OCT-based classification.
PURPOSE More than ten years after ETDRS, Optical Coherence Tomography (OCT) greatly enhanced our ability to detect macular thickening and has brought new insights on the morphology of edema and on the presence of vitreal traction. In this study we propose a new classification of macular edema based on OCT findings to better catalogue and follow this complex clinical entity. METHODS Since Janu...
