[Videooculography in evaluation of oculomotor function in patients with mass lesions of pineal region, midbrain and pons].

Aim of this study was to assess feasibility of videooculography in evaluation of oculomotor function and its dynamics in patients with mass lesions of pineal region, midbrain and pons. Computed videooculography was performed in 48 patients with tumors of pineal region and midbrain, 9 patients with pontine hematomas and 10 healthy volunteers. 25 patients with midbrain and pineal neoplasms were followed after tumor resection or open biopsy. We evaluated amplitude of eye movements in normal and impaired oculomotor function. 4 grades decreases of amplitude upwards, downwards, medially and laterally were emphasized. In early postoperative period statistically significant decrease of amplitude in patients with clinical deterioration was observed. Application of videooculography allows reliable quantitative assessment of oculomotor function, registration and storage of examination data and follow-up of oculomotor function for observation of tendencies in course of disease.
