Detailed imaging of the ciliary body region by means of ultrasound biomicroscopy can provide information that is crucial for further treatment, whereas clinical evaluation and 10-MHz standard B scan are less helpful. BACKGROUND: To evaluate the suitability of ultrasound biomicroscopy (UBM) for elucidating the causes of ocular hypotony. PATIENTS AND METHODS: A retrospective chart review was performed to determine the usefulness of UBM in the evaluation of ocular hypotony. UBM, B scan, and a detailed clinical examination had been performed. Sixty patient charts with prolonged ocular hypotony of different causes were reviewed from January 1994 to December 1998. The information obtained by the UBM was classified into three groups: 'diagnostic' (group 1); 'helpful' (group 2); and 'not helpful' (group 3). RESULTS: Of the 60 eyes, 45 UBM examinations (75%) were in group 1, nine eyes (15%) were assigned to group 2, and six eyes (10%) were in group 3. The duration of hypotony had no influence. CONCLUSIONS: In cases of ocular hypotony, the cause was related to ciliary body pathologies in 80%. Only UBM could distinguish tractional from dehiscence ciliary body detachment which required a different management approach. UBM with its high resolution imaging of the anterior segment - including the ciliary body - is highly suitable for diagnostic clarification.
