Abstract
Objective To study the effectiveness of scleral buckling without subretinal fluid drainage for macula-on rhegmatogenous retinal detachment (RRD), and to analyze the correlation between best-corrected visual acuity (BCVA) and the height of foveal subretinal fluid as well as the thickness of central retina measured by optical coherence tomography. Methods The medical records of 27 patients (27 eyes) who underwent scleral buckling without subretinal fluid drainage for macula-on RRD were retrospectively analyzed. The BCVA, height of foveal subretinal fluid and central subfield thickness (CST) were evaluated preoperatively and 1 week, 1 month, 3 months, 6 months and 12 months postoperatively. Results Postoperative BCVA of all eyes were improved significantly (P 0.05). Conclusions Scleral buckling without subretinal fluid drainage for macula-off RRD improved the BCVA, especially in the first 3 months postoperatively. The postoperative alterations of subretinal fluid and central foveal retinal thickness had no correlation with BCVA.
