To evaluate the correlation between metamorphopsia and outer retinal morphologic changes after successful vitrectomy for rhegmatogenous retinal detachment (RRD).
Forty eyes from 40 patients with macula-off (26 eyes) or macula-on (14 eyes) RRDs that underwent pars plana vitrectomy were included. Metamorphopsia was quantified with M-CHARTS. The relationship between the integrity of the outer retinal layers examined by spectral domain optical coherence tomography and metamorphopsia at 6 and 12 months postoperatively was evaluated.
Metamorphopsia was significantly more frequent in eyes with macula-off RRD (88%) than in eyes with macula-on RRD (21%) at 6 months postoperatively (P < 0.001) and became significantly less frequent in macula-off RRD eyes from 6 months to 12 months (64%) postoperatively (P = 0.041). Horizontal metamorphopsia scores in eyes with continuous interdigitation zone and ellipsoid zone bands were significantly smaller than in eyes with a disrupted interdigitation zone band and a continuous ellipsoid zone band or in eyes with disrupted ellipsoid zone and interdigitation zone bands (P = 0.003 and P <0.001, respectively), which was consistent with the results of vertical metamorphopsia scores.
Restoration of both the ellipsoid zone and interdigitation zone bands seems to be an important factor for the reduction of metamorphopsia after successful vitrectomy for macula-off RRD.
评估孔源性视网膜脱离（RRD）成功玻璃体切除术后变形视与视网膜外层形态学改变之间的相关性。
纳入40例接受玻璃体切除术的黄斑脱离（26只眼）或黄斑未脱离（14只眼）RRD患者的40只眼。使用M-CHARTS对变形视进行量化。评估术后6个月和12个月时通过光谱域光学相干断层扫描检查的视网膜外层完整性与变形视之间的关系。
术后6个月时，黄斑脱离RRD眼（88%）的变形视明显比黄斑未脱离RRD眼（21%）更常见（P < 0.001），且术后6个月至12个月时黄斑脱离RRD眼的变形视明显减少（64%）（P = 0.041）。具有连续指状交叉带和椭圆体带的眼的水平变形视评分明显低于具有中断的指状交叉带和连续椭圆体带的眼或具有中断的椭圆体带和指状交叉带的眼（分别为P = 0.003和P <0.001），这与垂直变形视评分结果一致。
对于黄斑脱离RRD成功玻璃体切除术后减少变形视而言，椭圆体带和指状交叉带的恢复似乎是一个重要因素。
