Govetto's staging system (stages 1-4) for epiretinal membrane (ERM) based on optical coherence tomography images is a useful predictor of monocular visual function; however, an association between Govetto's stage and binocular vision has not been reported. This study aimed to investigate the factors associated with Govetto's stage among the monocular and binocular parameters. This retrospective study included consecutive patients with treatment-naïve eyes with unilateral ERM without pseudo-hole. We investigated Govetto's stage, degrees of aniseikonia and metamorphopsia, foveal avascular zone area, central retinal and choroidal thickness, vertical ocular deviation, stereopsis, and binocular single vision (BSV). We compared the parameters between the BSV-present and BSV-absent groups and investigated correlations between Govetto's stage and the monocular and binocular parameters. Twenty-eight eyes of 28 patients were examined (age, 66.6 ± 10.2 years). In multivariate correlation analyses, Govetto's stage correlated with BSV (P = 0.04, β = - 0.36) and central retinal thickness (P < 0.001, β = 0.74). Of the eyes, 18 were assigned to the BSV-present group and 10 to the BSV-absent group. Govetto's stage was significantly more advanced in the BSV-absent group than in the BSV-present group (3.2 ± 0.8 vs 2.5 ± 0.7, P = 0.03). Of the 28 patients, 11 (39%) showed small-angle vertical deviations (1-12Δ). In conclusion, our findings showed that Govetto's stage correlated with binocular vision in patients with monocular ERM. Govetto's staging is a useful parameter for predicting not only monocular but also binocular vision.
Govetto 基于光学相干断层扫描图像的内界膜（ERM）分期系统（1-4 期）是预测单眼视力的有用指标；然而，Govetto 分期与双眼视觉之间的关系尚未报道。本研究旨在探讨与单眼和双眼参数相关的 Govetto 分期的因素。这项回顾性研究包括连续的未经治疗的单侧 ERM 且无假性孔的患者。我们研究了 Govetto 分期、双眼像差和变形程度、中心凹无血管区面积、中心视网膜和脉络膜厚度、垂直眼球偏斜、立体视和双眼单视（BSV）。我们比较了 BSV 存在和 BSV 缺失组之间的参数，并探讨了 Govetto 分期与单眼和双眼参数之间的相关性。共检查了 28 例 28 只眼（年龄 66.6±10.2 岁）。在多变量相关分析中，Govetto 分期与 BSV（P=0.04，β=-0.36）和中心视网膜厚度（P<0.001，β=0.74）相关。在这些眼中，18 只被分配到 BSV 存在组，10 只被分配到 BSV 缺失组。BSV 缺失组的 Govetto 分期明显比 BSV 存在组更严重（3.2±0.8 比 2.5±0.7，P=0.03）。在 28 例患者中，11 例（39%）存在小角度垂直偏斜（1-12Δ）。总之，我们的研究结果表明，在单眼 ERM 患者中，Govetto 分期与双眼视力相关。Govetto 分期不仅是预测单眼视力的有用指标，也是预测双眼视力的有用指标。
