Abstract
Purpose To observe the efficacy and safety of pars plana vitrectomy (PPV) combined with filtered air tamponade in the treatment of rhegmatogenous retinal detachment (RRD) with inferior retinal breaks. Methods This retrospective study included 20 patients (20 eyes) with inferior retinal breaks in RRD; all underwent PPV combined with filtered air tamponade. Preoperative examinations included BCVA, IOP, anterior segment, fundus and locations, numbers, and sizes of retinal breaks and ocular B-mode ultrasonography. Postoperative examinations included BCVA, IOP, residual gas volume, retinal reattachment, and complications. Results After follow-up for 1 year, the primary retinal reattachment rate was 95% and the final reattachment rate was 100%. Pre- and postoperative BCVA averaged 1.51 ± 0.63 and 0.97 ± 0.58 logMAR, respectively; the difference was statistically significant (P < 0.001). Average pre- and postoperative IOP were not statistically different. The average volume of residual gas on the first day after the surgery was 77.5%; the gas was absorbed in all patients within 2 weeks; no significant postoperative complications were observed. Conclusion PPV combined with filtered air tamponade is a safe and effective treatment for RRD with inferior retinal breaks. Notably, the retinal reattachment rate is high, gas absorption is rapid, and incidence of complications is low.
Highlights
Rhegmatogenous retinal detachment (RRD) is characterized by the formation of retinal breaks, which is the separation between the retinal neuroepithelium and pigment epithelium layers [1]
An inert gas bubble has strong pressure on the eye, can remain in the vitreous cavity for an extended period, and can be spontaneously absorbed; inert gas expands inside the eyes, leading to increased postoperative intraocular pressure (IOP) and potential blindness [2]
We observed the efficacy and complications of pars plana vitrectomy (PPV) combined with filtered air tamponade in the treatment of RRD with inferior retinal breaks, in order to explore the safety and efficacy of PPV combined with filtered air tamponade in the treatment of RRD with inferior retinal breaks
Summary
Rhegmatogenous retinal detachment (RRD) is characterized by the formation of retinal breaks, which is the separation between the retinal neuroepithelium and pigment epithelium layers [1]. It is a clinically common cause of blindness. Air does not expand in the eye, exhibits a short retention time in the vitreous cavity, and is readily absorbed and there are fewer postoperative complications. Air exhibits a short retention time in the vitreous cavity, along with rapid absorption and an associated brief period of pressure on the retina, especially for inferior retinal breaks. We observed the efficacy and complications of PPV combined with filtered air tamponade in the treatment of RRD with inferior retinal breaks, in order to explore the safety and efficacy of PPV combined with filtered air tamponade in the treatment of RRD with inferior retinal breaks
