Minimal segmental scleral buckling surgery for rhegmatogenous retinal detachment

Objective To compare the therapeutic effects of minimal segmental scleral buckling surgery and conventional scleral buckling in rhegmatogenous retinal detachment.Methods In this research,the postoperative retinal reattachment rate,best corrected visual acuity and complications of 60 eyes with rhegmatogenous retinal detachment treated during March 2008 to March 2009 were retrospectively studied. Of the 60 eyes,20 eyes were performed with minimal segmental scleral buckling surgery(group A) compared with the control group of 40 other randomly chosen eyes performed with conventional scleral buckling surgery(group B).Results The primary reattachment rate was 90% in group A and 95% in group B. Best corrected visual acuity was 0.48±0.33 in group A and 0.48±0.28 in group B. PVR developed in 5% of the eyes in group A and 10% in group B. There are no significantly differences between the two groups in all three aspects (P=0.4642,0.9662 and 0.5089,respectively). Complications happened in both groups,of which 3 eyes intraocular hypertensions ,1 eye macular oedema and 1 eye diplopia in group B while 1 eye diplopia in group A. The refraction change was statistically difference between the two groups (P=0.0019),while the changes of anterior chamber depth,axial length and astigmatism were not (P= 0.5444、0.8732、and 0.0582,respectively).Conclusion Extraocular pressure operation is an effective surgical method to treat retinal detachment,and the minimal segmental scleral buckling surgery can cure rhegmatogenous retinal detachment well which has less injury and can avoid some of the complications,but the long-term efficacy remains to further observation.
