    Optic Nerve Head Quantification in Idiopathic Intracranial Hypertension by Spectral Domain OCT

    Objective To evaluate 3D spectral domain optical coherence tomography (SDOCT) volume scans as a tool for quantification of optic nerve head (ONH) volume as a potential marker for treatment effectiveness and disease progression in idiopathic intracranial hypertension (IIH). Design and Patients Cross-sectional pilot trial comparing 19 IIH patients and controls matched for gender, age and body mass index. Each participant underwent SDOCT. A custom segmentation algorithm was developed to quantify ONH volume (ONHV) and height (ONHH) in 3D volume scans. Results Whereas peripapillary retinal nerve fiber layer thickness did not show differences between controls and IIH patients, the newly developed ...
