Background and objective: To describe the sonographic features of senile scleral calcification using ultrasound biomicroscopy.
Patients and methods: Four patients in whom senile scleral calcifications were found incidentally on computed tomography studies underwent ultrasound biomicroscopy examination.
Results: The senile scleral calcification was bilateral in three patients and unilateral in one patient. In all patients, the calcified material created the anterior shadowing typical of calcified lesions. The ultrasound biomicroscopy study localized the senile scleral calcification to the subconjunctival layer, superficially above the sclera, and anterior to the horizontal muscles.
Conclusions: This is the first description of the ultrasound biomicroscopy features of senile scleral calcification. Ultrasound biomicroscopy may serve as a good tool for the accurate localization of the plaque.
