Vitreopapillary Traction As a Cause of Elevated Optic Nerve Head

Purpose: To identify vitreopapillary tractional forces as a possible cause of optic nerve head elevation.

Methods: Case reports. Two patients aged 64 and 84 years underwent detailed ocular examination and B-scan ultrasonography.

Results: 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.

Conclusions: Vitreopapillary traction can cause unilateral optic nerve head elevation. The posterior hyaloid should be evaluated in patients with optic nerve head elevation.
