B scan US and eye-steering UWFI combo useful tool for retinal tear detection prior to cataract surgery, finds study

A study was done to investigate the efficacy of combined application of B-scan ultrasonography (US) and ultrawide field imaging (UWFI) in detecting retinal tears before cataract surgery. 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. Combined application of B-scan US and eye-steering UWFI presented satisfactory performance in detecting retinal tears before cataract surgery.
