The value of ultrasound biomicroscopy in the diagnosis of eyelid lesions is not well known.
Method: For examination of the eyelid lesions, we used an ultrasound biomicroscope (Humphrey, Zeiss, Oberkochen) with high fre-quency sound heads (30 and 50 Hz). Available for this study were all patients with eyelid lesions, which were operated on consecu-tively between November 1998 and January 1999. The results of ultrasound biomicroscopy were correlated with the histologic ex-aminations of these lesions.
Results: Nineteen patients (14 female, 5 male) with a mean age of 57.1 years, range 8 to 86 years were available for this study. Histologi-cal investigation displayed basal cell carcinoma (6/19), chalazion (4/19), cysts (2/19) seborrheic keratosis (2/19), a granulomatous process (2/19), epidermoid cyst (1/19), a pilomatrixoma (1/19), and a sebaceous cyst (1/19). With ultrasound biomicroscopy we were able to demonstrate a cyst or a cystic tumor in five patients (26%); i.e. two patients with a cyst of the eyelid, two patients with chala-zion and one patient with an epidermoid cyst. In the patients with solid tumors of the eyelid the definite diagnosis cannot be differen-tiated with ultrasound biomicroscopy. The surface of the tumor of the patients with seborrheic keratosis was high reflective with pos-terior shadowing of the underlying tissue. In the patient with the pi-lomatrixoma we were able to demonstrate calcification within the tumor.
Conclusion: For evaluation of eyelid lesions caused by a cyst or a solid tumor, ultrasound biomicroscopy may be an additional diagnostic tool, e.g. for assessment of the margins of the tumor. However, up to now it is not possible to differentiate different lesions based on ul-trasonographic findings.
