Choroidal thinning has been suggested in Leber’s hereditary optic neuropathy (LHON). No study has been conducted of the choroid in relation to the retinal ganglion cell-inner plexiform layer (RGC-IPL). We sought to measure choroidal thickness in chronic LHON and to correlate thickness changes with the RGC-IPL. Chronic LHON, 11778 mitochondrial DNA (mtDNA) mutation, patients (26 eyes; mean age: 35.1 ± 16.1 years) were prospectively recruited at Doheny Eye Center, University of California Los Angeles from March 2016 to July 2017. Age-matched healthy controls (27 eyes; mean age: 32.4 ± 11.1 years) were enroled for comparison. Swept-source optical coherence tomography (SS-OCT) imaging was performed in chronic LHON patients and compared with age-matched healthy controls. The macular choroid was significantly thinner in chronic LHON (250.5 ± 62.2 μm) compared with controls (313.9 ± 60.2 μm; p < 0.0001). The peripapillary choroid was also significantly thinner in chronic LHON (135.7 ± 51.4 μm) compared with controls (183.0 ± 61.8 μm, p < 0.001). Choroidal thickness strongly correlated with retinal nerve fibre layer (RNFL) thickness in both the macular (R2 = 0.72; 95% CI, 0.57–0.84) and peripapillary regions (R2 = 0.53; 95% CI, 0.31–0.70). Choroidal thickness was also significantly correlated with macular RGC-IPL thickness (R2 = 0.51; 95% CI, 0.26–0.73). Choroidal thinning in chronic LHON correlated strongly with both RNFL and RGC-IPL thicknesses. These findings may suggest a pathophysiological mechanism involving vascular pathology of the choroid in relation to the retinal ganglion cell complex in LHON.

慢性 Leber's 遗传性视神经病变的脉络膜厚度和视网膜神经节细胞复合体:一项使用扫描源光学相干断层扫描的前瞻性研究

在 Leber 遗传性视神经病变 (LHON) 中已提出脉络膜变薄。尚未对脉络膜与视网膜神经节细胞内丛状层 (RGC-IPL) 进行研究。我们试图测量慢性 LHON 的脉络膜厚度,并将厚度变化与 RGC-IPL 相关联。2016 年 3 月至 2017 年 7 月在加州大学洛杉矶分校 Doheny 眼科中心前瞻性招募慢性 LHON、11778 线粒体 DNA (mtDNA) 突变患者(26 只眼;平均年龄:35.1 ± 16.1 岁)。年龄匹配的健康对照( 27 只眼;平均年龄:32.4 ± 11.1 岁)进行比较。在慢性 LHON 患者中进行扫描源光学相干断层扫描 (SS-OCT) 成像,并与年龄匹配的健康对照进行比较。慢性 LHON 患者黄斑脉络膜明显变薄 (250.5 ± 62. 2 μm) 与对照 (313.9 ± 60.2 μm; p < 0.0001) 相比。与对照组 (183.0 ± 61.8 μm, p < 0.001) 相比,慢性 LHON 的视盘周围脉络膜 (135.7 ± 51.4 μm) 也显着变薄。脉络膜厚度与黄斑区(R2 = 0.72;95% CI,0.57-0.84)和视乳头周围区域(R2 = 0.53;95% CI,0.31-0.70)的视网膜神经纤维层(RNFL)厚度密切相关。脉络膜厚度也与黄斑部 RGC-IPL 厚度显着相关(R2 = 0.51;95% CI,0.26-0.73)。慢性 LHON 的脉络膜变薄与 RNFL 和 RGC-IPL 厚度密​​切相关。这些发现可能表明了一种病理生理机制,涉及与 LHON 中视网膜神经节细胞复合体相关的脉络膜血管病理学。与对照组 (183.0 ± 61.8 μm, p < 0.001) 相比,慢性 LHON 的视盘周围脉络膜 (135.7 ± 51.4 μm) 也显着更薄。脉络膜厚度与黄斑区(R2 = 0.72;95% CI,0.57-0.84)和视乳头周围区域(R2 = 0.53;95% CI,0.31-0.70)的视网膜神经纤维层(RNFL)厚度密切相关。脉络膜厚度也与黄斑部 RGC-IPL 厚度显着相关(R2 = 0.51;95% CI,0.26-0.73)。慢性 LHON 的脉络膜变薄与 RNFL 和 RGC-IPL 厚度密​​切相关。这些发现可能表明了一种病理生理机制,涉及与 LHON 中视网膜神经节细胞复合体相关的脉络膜血管病理学。与对照组 (183.0 ± 61.8 μm, p < 0.001) 相比,慢性 LHON 的视盘周围脉络膜 (135.7 ± 51.4 μm) 也显着变薄。脉络膜厚度与黄斑区(R2 = 0.72;95% CI,0.57-0.84)和视乳头周围区域(R2 = 0.53;95% CI,0.31-0.70)的视网膜神经纤维层(RNFL)厚度密切相关。脉络膜厚度也与黄斑部 RGC-IPL 厚度显着相关(R2 = 0.51;95% CI,0.26-0.73)。慢性 LHON 的脉络膜变薄与 RNFL 和 RGC-IPL 厚度密​​切相关。这些发现可能表明了一种病理生理机制,涉及与 LHON 中视网膜神经节细胞复合体相关的脉络膜血管病理学。脉络膜厚度与黄斑区(R2 = 0.72;95% CI,0.57-0.84)和视乳头周围区域(R2 = 0.53;95% CI,0.31-0.70)的视网膜神经纤维层(RNFL)厚度密切相关。脉络膜厚度也与黄斑部 RGC-IPL 厚度显着相关(R2 = 0.51;95% CI,0.26-0.73)。慢性 LHON 的脉络膜变薄与 RNFL 和 RGC-IPL 厚度密​​切相关。这些发现可能表明了一种病理生理机制,涉及与 LHON 中视网膜神经节细胞复合体相关的脉络膜血管病理学。脉络膜厚度与黄斑区(R2 = 0.72;95% CI,0.57-0.84)和视乳头周围区域(R2 = 0.53;95% CI,0.31-0.70)的视网膜神经纤维层(RNFL)厚度密切相关。脉络膜厚度也与黄斑部 RGC-IPL 厚度显着相关(R2 = 0.51;95% CI,0.26-0.73)。慢性 LHON 的脉络膜变薄与 RNFL 和 RGC-IPL 厚度密​​切相关。这些发现可能表明了一种病理生理机制,涉及与 LHON 中视网膜神经节细胞复合体相关的脉络膜血管病理学。慢性 LHON 的脉络膜变薄与 RNFL 和 RGC-IPL 厚度密​​切相关。这些发现可能表明了一种病理生理机制,涉及与 LHON 中视网膜神经节细胞复合体相关的脉络膜血管病理学。慢性 LHON 的脉络膜变薄与 RNFL 和 RGC-IPL 厚度密​​切相关。这些发现可能表明了一种病理生理机制,涉及与 LHON 中视网膜神经节细胞复合体相关的脉络膜血管病理学。
