Clinical Comparison Of Scleral Buckling Procedure For Retinal Detachment Under Microscope And Indirect Ophthalmoscope

Objective To explore the the similarities and differences between scleral buckling procedure(SBP) for rhegmatogenous retinal detachment under microscope and indirect ophthalmoscope in surgical indications, complications and success rate.Method Retrospectively analysed97consecutive patients’(97eyes)clinical data, undergoing scleral buckling procedure for rhegmatogenous retinal detachment performed by a single surgeon from Nov2010to Mar2013. According to surgical procedure, the patients were divided into two groups, SBP performing under indirect ophthalmoscope group(traditional group for short) and SBP performing under microscope group(microscope group for short).The traditional group included35patients whose procedure had done from Nov2010to Dec2011.The microscope group included62patients whose procedure had done from Jan2012to Mar2013. Two groups’homogeneity, surgical complications and success rate were compared.Results (1) The homogeneity comparison, including basic information relevant factors such as gender, age, course of disease and eye with desease and procedure decision related factors such as grade of PVR, subretinal proliferation cords, hole location and number of holes, indicated that the differences were not statistically significant (P>0.05), that is to say, two groups of patients can be considered homogeneous;(2) Success rate:Two groups’primary success rate were beyond90%(traditional group:94.28%, microscope group:90.32%), the differences were not statistically significant (P>0.05). Both groups had high success rate.(3)The comparison of two groups’surgical complications:high intraocular pressure existed in two groups postoperatively(traditional group:9eyes, microscope group:15eyes), but the differences were not statistically significant (P>0.05). The traditional group had one subretinal hemorrhage, and the microscopic group had one subretinal hemorrhage,one vitreous hemorrhage and one intraocular lens clamping.Conclusion The procedure for retinal detachment, taking scleral buckling, cryotherapy and drainage as the basic steps, which can be done under indirect ophthalmoscope can also be done under microscope. And at the same time it can achieve the same success rate, without increasing the surgical complications. And the procedure under microscope is easy to learn, operating convenient and has erect image comparatively.
