To compare the postoperative anatomic success rates and the frequency of complications between prone or supine postoperative positioning after transconjunctival sutureless vitrectomy (TSV) for rhegmatogenous retinal detachment (RRD).


All patients underwent primary 27-gauge TSV for the treatment of primary RRD. Patients were divided into two groups as follows: group A was patients instructed to keep strict postoperative prone positioning for a minimum of 8 days. Group B was patients instructed to keep the prone positioning on the day of the surgery followed by supine positioning for minimum of 7 days from the day after surgery.


Sixty-two eyes were enrolled (group A: 32, group B: 30). There was no significant difference in baseline data between two groups. The initial and final anatomical success rates were 93.8% and 100% in group A and 93.3% and 100% in group B, respectively (p = 1, p = 1, respectively). Posterior synechia of the iris occurred in one eye in group A and in two eyes in group B (p = 0.61). Macular pucker and retinal fold did not occur in either group. Preoperative intraocular pressure (IOP; mmHg) was 14.5 ± 2.9 in group A and 14.5 ± 2.6 in group B (p = 0.92). Intraocular pressure (IOP) was not statistically different between the groups during the follow-up period (p = 0.36, p = 0.07, respectively).


Supine positioning may be an option as a postoperative positioning after TSV and gas tamponade for the treatment of RRD.
