Clinical characteristics of primary pars plana vitrectomy combined with air filling for rhegmatogenous retinal detachment

Abstract

To detect the prognostic factors associated with initial reattachment after primary pars plana vitrectomy (PPV) with air tamponade for rhegmatogenous retinal detachment (RRD). We retrospectively reviewed 92 eyes of 92 patients with RRD. All eyes underwent PPV with air tamponade and a follow-up of at least 6 months. Initial anatomical success was defined as reattachment of the retina by a single operation. We performed univariate analysis to detect the presence of any difference between eyes with a successful initial reattachment and those that failed. We also performed multivariate logistic regression analysis to assess the influence of each preoperative factor on initial success. The rate of initial reattachment success was 93.5%. The percentage of retinal detachment involving the inferior quadrants in the initial success group was less than that in the initial failure group, and the difference was statistically significant (P = 0.043). There were no significant differences noted for other factors, such as symptom duration (P = 0.078) or location of retinal breaks (P = 0.065). Multiple logistic regression analysis using preoperative factors indicated that older age (odds ratio, 0.90; 95% confidence interval, 0.82–0.97; P = 0.010) and non-involvement of inferior quadrants (odds ratio, 9.90; 95% confidence interval, 1.36–71.92; P = 0.023) were significantly associated with initial success. PPV combined with air may be an effective treatment for some simple RRDs (proliferative vitreoretinopathy [PVR] grade ≤ C1). Non-involvement of the inferior quadrants and older age at presentation are associated with a greater likelihood of anatomic success. The volume of air in the eye after surgery is also very important, which may also affect the reduction of retinal detachment.

A Short-Time Real-World Study of Two Perfluoropropane Tamponade Methods in Pars Plana Vitrectomy for Retinal Detachment

“…We explored the efficacy, safety, and operative parameters of two C3F8 tamponade methods combined with PPV for RD in this study. In previous studies, the rate of retinal reattachment after Vitrectomy combined with C3F8 tamponade was 91.2%∼96.2% [6, 12‒14]. In our study, the single-surgery retinal reattachment rates of pure group and mixed group were 97.4% and 96.8%, respectively.…”

“…Compared with the logMAR BCVA at baseline, both the two groups did not show significant change (respectively, 0.03 ± 0.98 vs. 0.14 ± 1.01, p = 0.837 vs. p = 0.183). For the slow absorption of long-acting gas like C3F8, it is hard to restore the patients’ vision in a short time [ 13 ]. Therefore, we studied patients with follow-up data more than 1 month after surgery.…”
