- Brief Summary
ARP is performed by a transperitoneal approach(I; head-down angle 25) and a retroperitoneal approach(R; head-down angle 5). *l approach has significantly less effect on IOP. *The influence of pneumoperitoneum pressure on IOP is not greater than that of head down position. *We investigated risk factors for increased IOP. As a results, the younger the age, and the heavier the weight are the risk factor for increasing the intraocular pressure only in the I approach group
