Relationship between Optic Nerve Head Drusen Volume and Structural and Functional Optic Nerve Damage
Purpose: To assess the relationships between optic nerve head drusen (ONHD) volume, retinal nerve fiber layer (RNFL) thickness and visual field (VF) loss. Methods: Patients with ONHD and no other ocular or systemic conditions that can affect RNFL or VF were enrolled. Serial enhanced depth imaging (EDI) optical coherence tomography (OCT) B-scans of the optic nerve head (interval between scans, ~30 [mu]m) were obtained from each participant. ONHD volume was calculated for each eye by delineating the ONHD masses in each OCT B-scan using 3-dimensional reconstruction software. Results: Forty-seven eyes (28 patients) with ONHD were included (mean age, 57 ...
