Scleral Buckling Using a Non-contact Wide-Angle Viewing System with a 25-Gauge Chandelier Endoilluminator

다국어 초록 (Multilingual Abstract)

Purpose: To report the outcome of scleral buckling using a non-contact wide-angle viewing system with a25-gauge chandelier endoilluminator.
Methods: Retrospective analyses of medical records were performed for 17 eyes of 16 patients with primaryrhegmatogenous retinal detachment (RRD) without proliferative vitreoretinopathy who had undergone conventionalscleral buckling with cryoretinopexy using the combination of a non-contact wide-angle viewingsystem and chandelier endoillumination.
Results: The patients were eight males and five females with a mean age of 26.8 ± 10.2 (range, 11 to 47)years. The mean follow-up period was 7.3 ± 3.1 months. Baseline best-corrected visual acuity was 0.23 ±0.28 logarithm of the minimum angle of resolution units. Best-corrected visual acuity at the final visit showedimprovement (0.20 ± 0.25 logarithm of the minimum angle of resolution units), but the improvement was notstatistically significant (p = 0.722). As a surgery-related complication, there was vitreous loss at the end ofsurgery in one eye. As a postoperative complication, increased intraocular pressure (four cases) and herpessimplex epithelial keratitis (one case) were controlled postoperatively with eye drops. One case of persistentRRD after primary surgery needed additional vitrectomy, and the retina was postoperatively attached.
Conclusions: Scleral buckling with chandelier illumination as a surgical technique for RRD has the advantagesof relieving the surgeon’s neck pain from prolonged use of the indirect ophthalmoscope and sharing the surgicalprocedure with another surgical team member. In addition, fine retinal breaks that are hard to identifyusing an indirect ophthalmoscope can be easily found under the microscope by direct endoillumination.
