Abstract
Purpose: To report the rate and rationale for vitrectomy (PPV) following retinal detachment (RD) repair with pneumatic retinopexy (PnR).
Participants: IRIS® Registry (Intelligent Research in Sight) patients undergoing PnR from 04/01/2013 to 12/31/2021.
Methods: Billing codes were used to apply inclusion/exclusion and define three groups for comparison following PnR. Group 1 eyes had a non-RD PPV following PnR. Group 2 did not require a surgical procedure following PnR. Group 3 had RD that required surgical repair following PnR.
Main outcome measures: Subsequent PPV for indications other than RD repair, follow-up duration and visual acuity (VA).
Results: 9,488 eyes of 9,401 patients met the study criteria. Mean age was 65 and most were males (60.2%). 9,107 of these eyes were analyzed according to the inclusion/exclusion criteria. Group 1 included 556 eyes, Group 2 included 5,351, and Group 3 included 3,200. In Group 1, PPV alone was performed in 30.8% (171 eyes), internal limiting membrane was removed in 25.7% (143 eyes), and epiretinal membrane was removed in 18.3% (102 eyes). Panretinal or focal endolaser photocoagulation was performed with a PPV in 13.3% (74 eyes) and 11.9% (66 eyes), respectively. Average baseline VA in Group 1 (0.35 logMAR, 20/45) was similar to Group 2 (0.33 logMAR, 20/43). Mean final VA was lower (0.33 logMAR (20/43) versus 0.21 logMAR (20/32), p<0.001), mean follow-up duration was longer (1,556 days versus 1,227, p<0.001), and more were male (63.3% versus 56.1%, p=0.006). Mean follow-up duration was longer than Group 3 (1,401 days, p=0.002) while final VA was similar to Group 3 (0.38 logMAR (20/48), p=0.50). 64.9% (5,907 eyes) were reattached using PnR and 9.4% (556) of these required a non-RD PPV.
Conclusions: Nearly one in 10 eyes required a non-RD PPV following reattachment with PnR. VA outcomes were similar to eyes requiring surgical repair for RD. The possible need for PPV after reattachment with PnR should be addressed when counseling patients.
