简要总结
The purpose of this study is to evaluate whether postoperative postures influence persistent sub-foveal fluid after scleral buckle surgery
详细描述
In this study, we are to compare the difference of influence of two postoperative postures on the incidence and duration of persistent sub-foveal fluid after scleral buckle surgery for macula-off retinal detachment

研究组 & 干预措施
supine
postoperative postures: patients in this arm are assigned to adopt supine position for 24 hours after the surgery
干预措施: postoperative postures (Behavioral)

干预措施: postoperative postures (Behavioral)
结局指标
主要结局
duration of absorption of persistent sub-foveal fluid after surgery
时间窗: Time from the date of operation until the date of absorption of sub-foveal fluid determined by OCT. The estimated period of time over which the event (absorption of sub-foveal fluid ) is assessed is up to 1 year.
time interval from surgery to the date of disappearance of sub-foveal fluid on OCT
次要结局
- best corrected visual acuity(6 months after surgery)
