Study Overview
Brief Summary
The purpose of this study is to evaluate whether postoperative postures influence persistent sub-foveal fluid after scleral buckle surgery
Detailed Description
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

Inclusion Criteria
- •rhegmatogenous retinal detachment (RRD)
- •macula off
- •treated by successful scleral buckle surgery
- •recent onset with symptom within 1 month
Exclusion Criteria
- •with failed previous surgery
- •intraoperative or postoperative injection of long-acting gas

Outcomes
Primary Outcomes
duration of absorption of persistent sub-foveal fluid after surgery
Time Frame: 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
Secondary Outcomes
- best corrected visual acuity(6 months after surgery)
