Demographic data and parameters of the visual field, retinal nerve fiber layer thickness, and optic disc morphology of the subjects.

VF defect: Visual field defect after robot-assisted laparoscopic radical prostatectomy Gender(M/F): Gender(Male/Female) BMI: Body mass index. VF interval: Time interval between the surgery and the initial visual field test Operation time: Duration of robot-assisted laparoscopic radical prostatectomy OPP: Ocular perfusion pressure; OPP = mean arterial pressure—intraocular pressure * Mean blood pressure is an average value of the mean arterial pressure during the surgery. **OPP is calculated as mean values of the both eyes in the 18 subjects without VF defect and mean values of the unilateral 7 eyes with VF defect in the other 7 subjects and integrated during the operation time.
