Abstract Purpose:This study was performed to evaluate the factors of ocular hypertension for rhegmatogenous retinal detachment(RRD)after surgery.

Subjects and methods:We included 46 eyes of 45 consecutive patients(male, 28;female, 17;age 17〜79 years old, average 54.5 years old)who were followed up for at least six months after undergoing Pars plana vitrectomy(PPV)or scleral buckling(SB)between April 2021 and February 2022 at Tohoku University. We retrospectively investigated the factors influencing the postoperative intraocular pressure(IOP).

Results:During the postoperative course at 1 and 3 months after surgery, the PPV group had significantly higher IOP compared to the SB group(p=0.038 at 1 month, p=0.027 at 3 months, Mann-Whitney U test). However, at 1 month after surgery, only two cases in the PPV group had an IOP of 21 mmHg or higher, and no cases were observed at 3 months after surgery. In 34 cases(73.9%), the maximum postoperative IOP was observed within 2 weeks of the surgery:23 cases(71.9%)in the PPV group, and 11 cases(78.6%)in the SB group. In addition, 13 patients(28.3%)had an IOP of 30 mmHg or higher after the operation(12 patients in the PPV group, and one in the SB group)and was significantly higher in the PPV group(p=0.035, Fisher's exact test). Furthermore, an IOP of 30 mmHg or higher after the operation was no significant difference between the only PPV group(21 cases)and the PPV with SB group(11 cases). An IOP of 30 mmHg or higher after the operation was no significant difference between the group that injected silicone oil(6 cases)and a group that injected SF6(25 cases). Six months postoperatively, four patients had postoperative ocular hypertension, and required eye drops for glaucoma.

Conclusions:Postoperative ocular hypertension is more likely when PPV is performed for RRD surgery than when SB is used.
