Correlation between Macular Volume and Focal Macular Electroretinogram in Patients with Retinitis Pigmentosa

Investigative Opthalmology & Visual Science, 2008
To determine whether a significant correlation exists between the morphology of the macula measured by optical coherence tomography (OCT) and the amplitude of focal macular electroretinograms (fmERGs) in patients with retinitis pigmentosa (RP).fmERGs were recorded in 43 patients with RP and 43 age-similar normal subjects, with a 15 degrees stimulus ...

Simultaneous segmentation of retinal surfaces and microcystic macular edema in SDOCT volumes [PDF]

SPIE Proceedings, 2016
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.
