Visual Evoked Potantial Measurements For Preoperative Evaluation With Vitreous Hemorrage
Gazi Üniv. Tıp Fak. Göz Hast AD.
In our study 30 patients with unilateral hypertansive vitreus hemorrage were evaluated preoperatively and prediction of visual prognosis was done by visual evoked potential measurements. Monopolar thecnique and 10-20-30 Hz frequencies were used. Maculary functions were evaluated by 10 Hz frequency. 20 Hz was used to evaluate paramaculary area (5°- 15° temporal arcuate). Global optic nerve functions were investigated with 30 Hz frequency.
