Ultrasound biomicroscopy findings in uveitic hypotony: a three-case report

Ocular hypotony is a serious but uncommon complication of uveitis, rarely documented with detailed imaging. Ultrasound biomicroscopy (UBM) provides high-resolution visualization of anterior and intermediate segment structures, helping to identify the underlying mechanisms and guide management. We present three cases of uveitic hypotony illustrating the contribution of UBM in determining the etiology and prognosis. Each case highlights distinct mechanisms, including cyclitic membrane formation, serous ciliary body detachment, and structural damage secondary to trauma. Clinical findings, UBM features, management strategies, and outcomes are described in detail to emphasize the diagnostic value of UBM in differentiating reversible from irreversible causes of hypotony. UBM is a valuable imaging tool in the assessment of uveitic hypotony, allowing precise identification of ciliary body changes and related complications. It helps distinguish acute reversible conditions such as ciliary detachment from chronic structural alterations like cyclitic membranes that carry a poor prognosis. Early detection through UBM may facilitate timely therapeutic interventions, preserve ocular integrity, and prevent progression to phthisis bulbi.
