Vitreopapillary traction as a cause of elevated optic nerve head.

Abstract

To identify vitreopapillary tractional forces as a possible cause of optic nerve head elevation. Case reports. Two patients aged 64 and 84 years underwent detailed ocular examination and B-scan ultrasonography. Both patients had a unilateral elevated optic nerve head with normal color vision, normal pupillary responses, and full kinetic perimetry. Biomicroscopic and B-scan ultrasonographic evaluation confirmed the presence of vitreopapillary traction. Vitreopapillary traction can cause unilateral optic nerve head elevation. The posterior hyaloid should be evaluated in patients with optic nerve head elevation.
