Evaluation of Dry Cautery Efficacy in Choroidotomy and Drainage of Sub retinal Fluid by Primary Scleral Buckling Procedure

Background and Objectives: Considering the fact that choroidotomy during scleral buckling is occasionally associated with some complications, this study was performed on patients at Tabriz Nikookari Hospital, to evaluate the efficacy of dry cautery in drainage of subretinal fluid during scleral buckling procedure. Materials and Methods: In a clinical trial, 36 eyes underwent scleral buckling for primary retinal detachment. After sclerotomy, choroid and retinal pigment epithelium were perforated by dry cautery, subretinal space was opened, and fluid drained from the hole. The success rate and all intra- and post-operative complications, followed at least for 3 months after operation; the statistical data were analyzed by McNemarʹs test. Results: This technique was successful for drainage in 31 (86%) of 36 eyes (p< 0.0001). Operative and post-operative complications that are occationally assotiated with the drainage of subretinal fluid, including subretinal hemorrhage, retinal break or incarceration in sclerotomy site, were not seen. Conclusion: The dry cautery after sclerotomy was used for successful subretinal fluid drainage and was not accompanied with any complications. We suggest performing this type of sudy in other centers and recommend reporting results to evaluate therapeutic role of this procedure.
