A Clinical Study On The Treatment Of Rhegmatogenous Retinal Detachment By Foldable Capsular Bucle Pressing And Traditional Scleral Buckling

BackgroundRetinal detachment（RD）refers to the separation of the retinal neural sensory layer（RNSL）from the retinal pigment epithelium（RPE）caused by trauma or diseases.RD can cause severe visual damage and high blindness rate.It can be divided into rhegmatogenous retinal detachment（RRD）and non-rhegmatogenous retinal detachment.RRD is the most common form of retinal detachment clinically.It refers to the "rupture" of the retina and the passage of liquefied vitreous under the retina through a hole,resulting in RD.Surgery is the main treatment for RRD.At present,scleral bucking（SB）,pars plana Vitrectomy（PPV）and pneumatic retinopexy are the three main surgical methods for RD.Foldable capsular Bucle（FCB）is an improvement on SB,which is currently recognized as the standard surgical method for the treatment of simple RRD.ObjectiveTo compare the clinical effect of FCB and SB in the treatment of RRD,and the secondary objective was to analyze and evaluate the economic measures of treatment and postoperative quality of life.MethodsThe clinical data of 32 uncomplicated retinal detachment patients who received foldable capsular bucle from July 2018 to December 2020 and uncomplicated retinal detachment patients who received conventional scleral pressing scleral buckling were retrospectively analyzed.Patients treated with foldable capsular bucle were classified as group B and patients treated with conventional scleral pressure were classified as group V.Preoperative and postoperative examination data were recorded,including B-ultrasonography,fundus photography and retinal hiatus reduction.The two groups were compared for surgical success in terms of the best corrected visual acuity（BCVA）,intraocular pressure（IOP）,and persistent subretinal fluid（SRF）for at least 12 weeks postoperatively.Results32 eyes in group B and 29 eyes in group V.The best corrected visual acuity（BCVA）and intraocular pressure（IOP）were improved in both groups at 3 months follow-up,and the final postoperative success rate was 100% in both groups.No serious complications related to FCB occurred in patients with successful retinal reattachment in group B.In group B,9 eyes showed persistent SRF postoperatively,while in group V,1 eye showed persistent SRF.ConclusionIn the treatment of simple RRD,FCB and SB can effectively improve BCVA status and IOP of patients.FCB group surgical anesthesia method is safer,does not need to pull the extraocular muscle,there is no risk of ocardial reflex.The procedure takes less time and the clinician has a shorter learning curve.Postoperative complications are controllable and safe.It is suitable for people who are easy to be nervous,the elderly,children and so on.
