Features of Ultrasound Biomicroscopy and Optical Coherence Tomography in the Diagnosis of Forein Bodies Injuries of Anterior Segment of Eye

Abstract

Purpose. To evaluate the features of ultrasound biomicroscopy (UBM) and anterior segment optical coherence tomography (AS-OCT) in cases of foreign bodies (FB) injuries. Materials and methods. 25 patients (25 eyes) with suspected foreign bodies of AS were observed. Besides of the standard ophthalmological examination UBM and AS-OCT were performed. Results. Using the biomicroscopy nonpenetrating corneal injury with glass (2 eyes), metal (1 eye) and wood (1 eye) were diagnosed in 4 patients, but their exact location was difficult. AS-OCT allowed to specify the location and size of the foreign body (FB) and determined the penetration of cornea in 1 case. Penetrating wound of AS with glass (3 eyes), metal (16 eyes), plastic (1 eye) were diagnosed in 21 patients using biomicroscopy. X-ray examination was performed in 13 patients, in 5 of them FB of AS was revealed and suspected Fb in 3 cases. We determined FB of lower eyelid in 1 case. AS-OCT confirmed the presence of FB in almost all cases (20 eyes) independently of nature of FB and only in 1 case FB was not visualized. The localization, the size of the FB and the condition of surrounding tissues were determined using UBM and OCT. Data of AS-OCT - and UBM were correlated with those of X-ray examination. Conclusions. In cases of foreign bodies injuries of anterior segment AS-OCT and UBM allow to determine the location, the size of FB, their relationship with the surrounding tissues. Due to the diagnostic features of UBM and AS-OCT in patients with foreign bodies injuries of AS, the management of these patients has been identified.
