Background: To observe the short-term efficacy of vitrectomy for wide-angle observation system without perfluorocarbon liquid (PFCL )in the treatment of rhegmatogenous retinal detachment(RRD) with Proliferative vitreous retinopathy (PVR ) ≦C2.
Methods: Retrospective analysis of the case data of patients with rhegmatogenous retinal detachment who did not use or use perfluorocarbon liquid during vitrectomy, including age, sex, course of disease, PVR classification, preoperative and stepwise best corrected positive vision , Perfluorocarbon liquid in the perfluorocarbon liquid group, the reposition state of the retina, the difference in visual acuity recovery and retina reset rate within and between groups.
Results: There was no statistically significant difference in baseline data (age, sex, course of disease, PVR grade) between the non-perfluorocarbon liquid group and the perfluorocarbon liquid group (P> 0.05). The rate of initial reset at the time of discharge from the non-perfluorocarbon liquid group was 92.9%. The retinal reposition rate at 6 months after surgery was 100%. The rate of initial reduction at discharge was 93.5% in the group using perfluorocarbon liquid, and the final retinal reduction rate at 6 months after surgery was 100%. There was no statistically significant difference in logMAR BCVA of postoperative follow-up time between the two groups (P> 0.05). Without the use of perfluorocarbon liquid, there was no postoperative perfluorocarbon liquid residue, and the residual rate of perfluorocarbon liquid in the perfluorocarbon liquid group was 14.5%.
Conclusion: Vitrectomy without the use of perfluorocarbon fluids under the wide-angle observation system is the first choice to treat rhegmatogenous retinal detachment with PVR≤C2.
