测量眼内肿瘤的最大基底尺寸（LBD）对于预后参数而言是重要的。为了评估真彩色超广角眼底摄影在测量肿瘤中的潜在价值，我们比较了使用真彩色超广角眼底摄影机和间接眼底镜检查以及标准化眼科超声检查所得到的LBD测量结果之间，对脉络膜和视网膜肿瘤的LBD进行测量。使用真彩色超广角眼底摄影对龙仁医院148名患者的148个脉络膜和视网膜肿瘤的LBD进行了测量，并与B型超声波测量和间接眼底镜检查所得到的测量结果进行了比较。经过配对t检验和布兰特－阿尔特曼图分析表明，超广角眼底摄影图像测量结果在统计上与临床估计结果以及超声波测量结果没有显著差异。结果还显示，尽管没有统计学意义，但当肿瘤边界清晰、高度小于3毫米或肿瘤有色素时，超广角眼底摄影测量结果倾向于大于超声波测量结果。使用超广角眼底摄影测量的LBD结果与超声波和临床估计结果有很好的相关性，可以作为测量脉络膜和视网膜肿瘤LBD的可靠工具。©2023. 作者。

Measurement of the largest basal dimension (LBD) of intraocular tumors is important as a prognostic parameter. To evaluate the potential value of true color ultra-widefield fundus photography for measuring tumors, we compared LBD measurements of choroidal and retinal tumors using a color ultra-widefield fundus camera with clinical estimation based on indirect ophthalmoscopy and standardized ophthalmic ultrasound.The LBD of 148 choroidal and retinal tumors in 148 patients seen at Tongren Hospital were measured using ultra-widefield fundus photography and compared with measurements obtained using B-scan ultrasonography and clinical estimates based on indirect ophthalmoscopy.Paired t-tests and Bland-Altman plots reveal that measurements from ultra-widefield fundus photographic images are not statistically different from clinical estimates and ultrasound measurements. The results also showed that, although not statistically significant, when the tumor boundary was clear, the height was < 3 mm, or the tumor was pigmented, measurement from ultra-widefield fundus photography tended to be greater than those obtained by ultrasound.The LBD measurement using ultra-widefield fundus photography correlated well with ultrasonography and clinical estimation and could be used as a reliable tool for measuring the LBD of choroidal and retinal tumors.© 2023.
