目的：观察不同年龄段中心性浆液性脉络膜视网膜病变(CSC)患者患眼及其无症状对侧眼的影像学特征。

方法：回顾性研究。选取2023-04/09在我院眼科确诊的CSC患者76例88眼及单眼CSC患者无症状对侧眼35例35眼纳入研究。根据年龄分为中青年组(<40岁)、中年组(40-50岁)和中老年组(>50岁)，观察不同年龄段CSC患者患眼及其无症状对侧眼的影像学特征。

结果：中青年组患者患眼中心凹下脉络膜厚度(SFCT)(487.30±83.33 μm)明显大于中年组(414.17±96.02 μm，P<0.05)和中老年组(409.4±107.42 μm，P<0.05)。中老年组患者患眼脉络膜新生血管(CNV)发生率明显高于中年组(P<0.0167)。中青年组患者对侧眼SFCT(511.29±40.89 μm)明显大于中老年组(364.76±82.26 μm，P<0.05)。纳入患者患眼涡静脉吻合率高于90%，且对侧眼均存在涡静脉吻合或扩张。

结论：不同年龄段CSC患者患眼及其无症状对侧眼影像学表现存在差异，SFCT普遍增厚，且随着年龄增长逐渐变薄，中老年患者患眼CNV发生率最高，同时，CSC患者患眼及其无症状对侧眼普遍存在涡静脉吻合及扩张。

METHODS: Retrospective study. A total of 76 cases(88 eyes)of CSC patients diagnosed in the ophthalmology department of our hospital from April to September, 2023 and 35 cases(35 eyes of asymptomatic fellow eyes of patients with unilateral CSC)were selected for the study. According to age, they were divided into young and middle-aged groups(<40 years old), middle-aged groups(40-50 years old)and middle-aged and elderly groups(>50 years old). The imaging features of the affected eyes of CSC patients of different ages and their asymptomatic fellow eyes were observed.

RESULTS: The subfoveal choroidal thickness(SFCT)of CSC eyes in the young and middle-aged patients(487.30±83.33 μm)was significantly greater than that of the middle-aged group(414.17±96.02 μm, P<0.05)and the middle-aged and elderly group(409.4±107.42 μm, P<0.05). The incidence of choroidal neovascularization(CNV)in CSC patients of the middle-aged and elderly group was significantly higher than that in the young and middle-aged group(P<0.0167). The SFCT of the asymptomatic fellow eye of the unilateral CSC patient in the young and middle-aged group(511.29±40.89 μm)was significantly larger than that of the middle-aged and elderly group(364.76±82.26 μm, P<0.05). Among them, the vortex vein anastomosis rate in eyes with CSC is higher than 90%, and vortex vein anastomosis or dilatation is present in all asymptomatic fellow eyes of CSC patients.

CONCLUSION: There are differences in the imaging manifestations of CSC-affected eyes and their asymptomatic fellow eyes of different age groups. SFCT is generally thickened and gradually becomes thinner with the growth of age. The incidence of CNV in CSC-affected eyes is the highest in the middle-aged and elderly group. In addition, vortex vein anastomosis and dilatation are common in CSC-affected eyes and asymptomatic fellow eyes.
