Differentiating Mild Papilledema and Buried Optic Nerve Head Drusen Using Spectral Domain Optical Coherence Tomography – Corrected Proof
Purpose: To evaluate the clinical utility of spectral domain optical coherence tomography (SD-OCT) in differentiating mild papilledema from buried optic nerve head drusen (ONHD).Design: Comparative case series.Participants: Sixteen eyes of 9 patients with ultrasound-proven buried ONHD, 12 eyes of 6 patients with less than or equal to Frisén grade 2 papilledema owing to idiopathic intracranial hypertension. Two normal fellow eyes of patients with buried ONHD were included.Methods: A raster scan of the optic nerve and analysis of the retinal nerve fiber layer (RNFL) thickness was performed on each eye using SD-OCT. Eight eyes underwent enhanced depth imaging SD-OCT. Images were (Read more...)
