PURPOSE: In this study we compared the anatomic and functional outcomes of two steroid treatments on rhegmatogenous retinal detachment (RRD) combined with choroidal detachment (CD), namely treatment with oral prednisolone (1 mg/kg daily) for 3-7 days before vitrectomy or a single periocular injection of methylprednisolone (40 mg) 1-3 days before vitrectomy. We also analyzed the outcomes of the eyes with subsided CD and the eyes with persistent CD that underwent drainage of suprachoroidal fluids during the vitrectomy.METHODS: This was a prospective randomized study. Seventy five eyes with RRD combined with CD were divided into 2 groups based on the two different treatment regimens as above. The eyes in each group were further divided into 2 subgroups (A: CD subsided eyes; B: CD persistent eyes) according to the response of CD to the treatment of steroids. Retinal reattachment rates were measured at 6 months after the removal of silicone oil.RESULTS: At 6 months after silicone oil removal, the retinal reattachment rate was similar (p = 0.666) in the oral prednisolone group (91.7%, 33/36) and the periocular injection group (94.9%, 37/39). Similar retinal reattachment rates (p = 0.364) were also found in the CD subsided eyes (97.1%, 34/35) and the CD persistent eyes (90.0%, 36/40). The retinal reattachment rate was comparable among the subgroups (p = 0.395; oral prednisolone A group: 95.2%, 20/21; oral prednisolone B group: 86.7%, 13/15; periocular injection A group: 100%, 14/14; periocular injection B group: 92.0%, 23/25).CONCLUSIONS: For RRD combined with CD, eyes treated with a single periocular injection of methylprednisolone (40 mg, 1-3 days before pars plana vitrectomy) combined with the drainage of suprachoroidal fluids during the surgery had similar anatomic and functional outcomes compared to the eyes treated with oral prednisolone for 3-7 days before vitrectomy.
