Purpose:
To correlate the ultrasound biomicroscopy (UBM) appearance of eyelid lesions with the results of histopathologic examination.
Methods:
Fifty-two patients with eyelid lesions were evaluated using 50-MHz UBM, and the UBM scans were compared with the histopathologic findings. The obscuration of the normal lid sonographic layers and invasion into adjacent tissues were criteria suggesting malignancy.
Results:
UBM characteristics of different eyelid lesions are presented. The sensitivity of UBM in detecting malignancy ranged from 78% to 86%, whereas the specificity ranged from 37% to 69%.
Conclusion:
This study of eyelid lesions shows that UBM can help differentiate between various benign and malignant lid lesions.
