VITREOPAPILLARY TRACTION AS A CAUSE OF ELEVATED OPTIC-NERVE HEAD

PURPOSE: To identify vitreopapillary tractional forces as a possible c ause of optic nerve head elevation. METHODS: Case reports. Two patient s aged 64 and 84 years underwent detailed ocular examination and B-sca n ultrasonography, RESULTS: Both patients had a unilateral elevated op tic nerve head with normal color vision, normal pupillary responses, a nd full kinetic perimetry, Biomicroscopic and B-scan ultrasonographic evaluation confirmed the presence of vitreopapillary traction. CONCLUS IONS: Vitreopapillary traction can cause unilateral optic nerve head e levation. The posterior hyaloid should be evaluated in patients with o ptic nerve head elevation.
