Abstract

PURPOSE

To investigate the efficacy of combined application of B-scan ultrasonography (US) and ultrawide field imaging (UWFI) in detecting retinal tears before cataract surgery.

METHODS

Of 1,277 cataract patients, 2,552 eyes were enrolled and received both B-scan US and UWFI examinations preoperatively. Three types of combination were applied: type 1 (union, B-scan US or centered UWFI), type 2 (intersection, B-scan US and centered UWFI), and type 3 (B-scan US and eye-steering UWFI). Sensitivity and specificity of detecting retinal tears by different methods were assessed.

RESULTS

Totally 4.55% (116/2,552) of eyes were presented with retinal tears. The sensitivity of B-scan US and UWFI was 87.93% and 84.48%, and specificity was 95.16% and 99.79%, respectively. By applying type 1 and type 2 combination, the sensitivity was 98.28% and 74.14%, and specificity was 95.03% and 99.92%, respectively. By type 3 combination, the sensitivity increased to 95.69% and specificity to 99.88%, both of which were comparable to indirect ophthalmoscopy regardless of the number, type, and location of tears ( P > 0.05). In eyes with any cataract type or axial length, type 3 combination also gained comparable performance to indirect ophthalmoscopy.

CONCLUSION

Combined application of B-scan US and eye-steering UWFI presented satisfactory performance in detecting retinal tears before cataract surgery.

摘要

目的

研究在白内障术前应用 B 型超声（B-scan US）和超广角成像（UWFI）联合检测视网膜裂孔的效果。

方法

纳入 1277 例白内障患者的 2552 只眼，均行术前 B-scan US 和 UWFI 检查。三种联合方式如下：联合 1 型（融合，B-scan US 或中心 UWFI）、联合 2 型（相交，B-scan US 和中心 UWFI）和联合 3 型（B-scan US 和眼球追踪 UWFI）。评估不同方法检测视网膜裂孔的灵敏度和特异度。

结果

共 4.55%（116/2552）的眼存在视网膜裂孔。B-scan US 和 UWFI 的灵敏度分别为 87.93%和 84.48%，特异度分别为 95.16%和 99.79%。应用联合 1 型和联合 2 型，灵敏度分别为 98.28%和 74.14%，特异度分别为 95.03%和 99.92%。应用联合 3 型，灵敏度提高至 95.69%，特异度提高至 99.88%，与间接检眼镜比较，无论裂孔数量、类型和位置，均差异无统计学意义（P＞0.05）。在任何白内障类型或眼轴长度的眼中，联合 3 型与间接检眼镜的表现也相当。
