Purpose: To assess pattern reversal visual evoked potentials (PRVEP) changes in patients with proptosis.Abstract
Methods: This was a cross-sectional, hospital-based study including 40 patients with either unilateral or bilateral proptosis who fulfilled the inclusion and exclusion criteria and gave informed written consent. The period of study was 18 months. The tools used were Hertel’s exophthalmometer and visual evoked potential.
Result: The result of the present study was, increase in grades of proptosis, resulting in increased delay in PRVEP P-100 latency and decreased N70-P100 amplitude.
Conclusion: PRVEP is an important tool for the diagnosis of optic nerve involvement in proptosis.
