[Possibilities of ultrasound methods in diagnostics of eyelid tumors]

To determine the informative value of ultrasound biomicroscopy (UBM) with A-scan for assessment of qualitative and quantitative characteristics of eyelid tumors less than 5 mm in size.

The study included 25 patients (25 eyes) with eyelid tumors less than 5 mm in size. In addition to standard ophthalmic examination, complex ultrasound diagnostics including B-scan, Color Doppler imaging and UBM with A-scan were performed. The localization, size, structure of eyelid tumors and the state of perifocal tissues were evaluated. All patients underwent surgical treatment with following histological examinations of dissected tissues. Due to qualitative analysis of the studied formations and small number of included patients, there was no need in statistical analysis of the data.

Complex application of UBM and A-scan allowed specifying the localization, size, structure of the small-sized tumors and detecting typical echographic signs of benign or malignant properties of the pathological process. Ultrasound data (UBM and A-scan) of eyelid tumors was highly correlated to histological features.

UBM with A-scan can be recommended for differential diagnostics of small-sized tumors and optimizing their management.
