Abstract
Wide-angle viewing systems (WAVSs) were originally established for pars plana vitrectomy. However, their application to scleral buckling surgery was recently reported. In this study, we compared the outcomes of scleral buckling using a noncontact WAVS with that of scleral buckling using conventional indirect ophthalmoscopy for rhegmatogenous retinal detachment. The clinical records of 39 eyes (39 patients) with rhegmatogenous retinal detachment primarily treated between November 2012 and June 2014 at the Vitreo-Retina Surgical Division Clinic at the Department of Ophthalmology, Keio University Hospital were retrospectively reviewed. Scleral bucking was performed using WAVS with surgical placement of an endoilluminator in 16 eyes and indirect ophthalmoscopy in 23 eyes. The patients in these groups were consecutive over different intervals. The preoperative demographics, success rate of retinal reattachment, intraoperative findings, and postoperative complications were evaluated. There were no significant differences in pre- or postoperative conditions between groups, and similar surgical outcomes were achieved with the WAVS and conventional procedures. However, compared with the conventional procedure, the WAVS procedure resulted in fewer intraoperative corneal epithelial disorders (p = 0.049) and decreased the surgical duration of segmental buckling (p = 0.02); therefore, it may be suggested as an effective alternative procedure.
Highlights
Wide-angle viewing systems (WAVSs) were originally established for pars plana vitrectomy
We included 23 eyes of 23 patients (18 men and 5 women; average age, 45.3 ± 1 2.5 years; range, 23–68 years) who underwent scleral buckling with conventional indirect ophthalmoscopy and 16 eyes of 16 patients (10 men and 6 women; average age, 41.3 ± 14.0 years; range, 24–65 years) who underwent scleral buckling with WAVS
The surgical procedure was selected depending on the period; the conventional procedure was selected in the initial period and WAVS was selected in the later period
Summary
Wide-angle viewing systems (WAVSs) were originally established for pars plana vitrectomy Their application to scleral buckling surgery was recently reported. We compared the outcomes of scleral buckling using a noncontact WAVS with that of scleral buckling using conventional indirect ophthalmoscopy for rhegmatogenous retinal detachment. An attempt to improve the method of scleral buckling by the substitution of indirect ophthalmoscopy with a noncontact wide-angle viewing system (WAVS) was recently made[1,2,3], no study has compared the surgical outcomes of the two procedures. In this study, we compared the two procedures with regard to the success rate of retinal reattachment, intraoperative findings, and postoperative complications in order to elucidate the effectiveness of WAVS-assisted scleral buckling and establish its use
