AIM: To evaluate the ocular parameter changes following scleral buckling(SB)for rhegmatogenous retinal detachment(RRD).

METHODS: This retrospective, non-randomized case-control study included 46 eyes of 23 patients who underwent SB for RRD. Best corrected visual acuity(BCVA), diopter, intraocular pressure(IOP), anterior chamber depth(ACD), the number of corneal endothelial cells, axial length and the degree of exophthalmos were evaluated in the operated eyes and the follow eyes postoperatively at 3mo.

RESULTS: After SB surgery, retina reattachment was achieved without any obvious complications or adverse reactions in all follow-up patients. Among all parameters, the significant decrease in BCVA of 0.15(LogMAR BCVA, P=0.007), in anterior chamber depth(ACD)of 0.29mm(P=0.011)and increase in the degree of exophthalmos of 0.54mm(P=0.047)were observed; the surgery-induced changes for other parameters, including diopter, IOP, counts of endothelial cells and axial length, were not significantly different(P>0.05).

CONCLUSION: SB is a good technique for repairing RRD. It brings SB-induced changes in ACD and the degree of exophthalmos.
