Factors associated with visual field defects of optic disc drusen.

ABSTRACT:

Purpose

To investigate the prevalence and risk factors for visual field defect in patients with optic disc drusen (ODD).

Methods

We assessed the visual field status of patients with ODD whose diagnosis were confirmed by spectral-domain optical coherence tomography (SD-OCT). Visual field defects were classified as normal, enlarged blind spot, or other defects. ODD were classified into either type 1 (without hyperreflective border and heterogenic internal reflectance) or type 2 (with hyperreflective border and lower internal reflectance). The prevalence and risk factors for each visual field defect was analyzed using logistic regression analysis and classification and regression tree (CART) modeling.

Results

Of the 40 eyes with ODD, 33 (83%) eyes were categorized as typ
