Optic disc and visual test findings in patients with migraine.

This study was conducted to determine whether the optic disc appearance and the visual field parameters of patients with migraine vary from those of age-matched controls. Twenty-two patients with migraine and 20 control participants were enrolled in the study. The automated visual field tests by Humphrey Field Analyzer® and optic disc images by Topcon® fundus camera were obtained from each participant. Horizontal and vertical cup-to-disc ratios were calculated by a manual, planimetric technique performed by two independent observers. The visual field indices including mean deviation (MD) and pattern standard deviations (PSD) were documented. No difference was found in the average cup-to-disc ratio between patients with migraine and control participants. However, MD and PSD of the groups were different. The average MD in the migraine group was -0.86+1.21, and in the control group was 0.10+1.03 (p=0.009). The average PSD in the migraine group was 2.11+0.68 and in the control group was 1.68+0.44 (p=0.024). In conclusion, this study demonstrated that patients with migraine had decreased sensitivity in their visual fields compared to the control participants.
