Abstract
BackgroundTo investigate the anatomic and functional outcomes of pars plana vitrectomy (PPV) with partial tamponade of filtered air for rhegmatogenous retinal detachment (RRD) caused by superior retinal breaks.MethodsRetrospective, comparative, consecutive case series study. Patients with RRD caused by superior retinal breaks undergone PPV with partial tamponade (Group A) and whole tamponade (Group B) of filtered air were included. The main outcomes were primary and final success rates, best corrected visual acuity (BCVA), and rate of postoperative cataract surgery.ResultsForty-one patients (41 eyes) were included in Group A and 36 patients (36 eyes) were included in Group B. There were no significant differences in primary or final success rates between Groups A and B (P = 0.618 and P = 1.000, respectively). The patients in Group A experienced quicker postoperative vision improvement (from the Week 1 follow-up) than the patients in Group B (from the Month 3 follow-up). The postoperative cataract surgery rate of Group A (7/31) was lower than that of Group B (13/26) (P = 0.031).ConclusionsPPV with partial tamponade of air is effective in achieving a high anatomic success rate, quicker postoperative vision improvement, and lower rate of postoperative cataract surgery in RRD caused by superior retinal breaks.

To investigate the anatomic and functional outcomes of pars plana vitrectomy (PPV) with partial tamponade of filtered air for rhegmatogenous retinal detachment (RRD) caused by superior retinal breaks
Previous studies have suggested that the outcomes of air tamponade used in treating RRD were comparable with those of long-acting gas tamponade, which is consistent with our clinical observations [8, 11, 12]
The medical records of all patients at Zhongshan Ophthalmic Center who underwent 23/25-gauge PPV with filtered air tamponade from May 1, 2014 to September 1, 2015 to treat RRD caused by superior retinal breaks were reviewed retrospectively, and written consent for surgical treatment had been obtained from each subject
Summary
To investigate the anatomic and functional outcomes of pars plana vitrectomy (PPV) with partial tamponade of filtered air for rhegmatogenous retinal detachment (RRD) caused by superior retinal breaks. RRD caused by superior retinal breaks puts patients in an urgent condition in which prompt surgical intervention is necessary to prevent rapid vision deterioration. Considering the potential risks of silicone oil tamponade and the necessity of secondary removal, the tendency is to use gas tamponade for the repair of RRD caused by superior retinal breaks without giant retinal tears or severe proliferative vitreoretinopathy [7,8,9,10]. Previous studies have suggested that the outcomes of air tamponade used in treating RRD were comparable with those of long-acting gas tamponade, which is consistent with our clinical observations [8, 11, 12]. Eyes that received gas tamponade had blurred vision from refractive changes until the gas bubble was absorbed to be above the
