To analyse the choroidal thickness (CT) and vessel pattern of myopic patients with dome-shaped macula (DSM) and their association with the DSM axis and serous retinal detachment (SRD).
Retrospective study. The CT and vessel pattern were assessed on optical coherence tomography (OCT), OCT-angiography and ultra-wide-field photography.
27 eyes of 18 subjects (mean age: 65 years) were included. Compared with the 11 eyes (41%) with horizontal DSM, the 16 eyes (59%) with vertical DSM had a shorter axial length (25.8±2 mm vs 28.3±2.5 mm; p=0.01), a higher mean macular bulge height (624.4±207 µm vs 255.4±160.3 µm; p=0.0001) and a thicker CT (183.1±91.1 µm vs 72±38.3 µm; p<0.001). Large choroidal vessels crossed the macular area in 75% of eyes with vertical DSM vs 27% of eyes with horizontal DSM (p=0.02), whereas a watershed zone framing the macula was more often seen in horizontal DSM (72% vs 25%, p=0.02). Thirteen eyes (48%) had an SRD that was not associated with the DSM axis, the mean bulge height, the CT or the vessel pattern.
The presence of an SRD did not correlate with the DSM axis, the CT or the vessel pattern. However, the rate of large choroidal vessels crossing the macula was higher in vertical DSM than in horizontal DSM.
分析盘状黄斑变性（DSM）伴大近视患者的脉络膜厚度（CT）和血管模式及其与 DSM 轴位和浆液性视网膜脱离（SRD）的关系。
回顾性研究。使用光学相干断层扫描（OCT）、OCT 血管造影和超广角摄影评估 CT 和血管模式。
纳入 18 名患者（平均年龄：65 岁）的 27 只眼。与 11 只（41%）水平型 DSM 相比，16 只（59%）垂直型 DSM 的眼轴更短（25.8±2mm 比 28.3±2.5mm；p=0.01），黄斑隆凸高度更高（624.4±207µm 比 255.4±160.3µm；p=0.0001），CT 更厚（183.1±91.1µm 比 72±38.3µm；p<0.001）。75%垂直型 DSM 眼的大脉络膜血管穿过黄斑区，而 27%水平型 DSM 眼有此现象（p=0.02），而水平型 DSM 更常见黄斑区周围分水岭（72%比 25%，p=0.02）。13 只眼（48%）有 SRD，与 DSM 轴位、隆凸高度、CT 或血管模式均无关。
SRD 的存在与 DSM 轴位、CT 或血管模式无关。然而，垂直型 DSM 中穿过黄斑的大脉络膜血管比例高于水平型 DSM。
