The efficacy of corticosteroid administration prior to vitrectomy for macular rhegmatogenous retinal detachment with choroidal detachment

Objective To evaluate the efficacy of corticosteroid administration prior to vitrectomy for macular rhegmatogenous retinal detachment with choroidal detachment.Methods Of 68 cases of macular rhegmatogenous retinal detachment with choroidal detachment,29 cases (Group A)received intensive 1% pre-dinisolone acetate eye drops or intravenous injection of 15 mg Dexamethasone or both above,and 39 cases (Group B)received pars plana vitrectomy and didn' t undertake any corticosteroid treatment.Main outcome measures:the rate of single-operation anatomic reattachment success,the rate of postoperative redetachment and the visual acuity.Results 18 eyes(62%)in Group A got choroidal reattachment in a week. ,the single op-eration anatomical rate of choroidal reattachment was 83.7% for Group A and 90.7% for Group B.The rate of anatomic retinal reattachment was 86.2% for Group A and 89.7% for Group B,the difference between them did not reach statistical significance (P>0.05).The vision improvement was a little more in Group B than that in Group A., however the rate of redetachment was almost the same after following-up.Cunclusions vitrectomy as early as possible played an important role in treatment of macular rhegmatogenous retinal detachment with choroidal detachment; the existence of choroidal detachment didn't have an effect on the reattachment of reti-nal detachment and the improvement of visual acuity.The corticosteroid administration prior to vitrectomy had no clinical significance.
