Purpose
To demonstrate the value of ultrasound biomicroscopy (UBM) in the evaluation of anterior segment trauma and its role in guiding treatment decisions and surgical planning. Blunt or penetrating ocular injuries may cause structural damage that is not fully appreciated on routine examination, especially in the presence of media opacity. Subtle findings such as zonular dialysis, cyclodialysis clefts, angle recession, iris defects, or small retained foreign bodies may be overlooked. UBM provides high-resolution imaging that enhances diagnostic accuracy, reveals occult pathology, and assists in grading injury severity and planning appropriate intervention.
Setting
Anterior segment trauma can present with a wide spectrum of findings, ranging from mild structural changes to vision-threatening complications. Blunt or penetrating injuries may result in hyphema, iridodialysis, cyclodialysis, angle recession, zonular dialysis, traumatic cataract, lens subluxation, or retained anterior segment foreign bodies. Many of these findings may be subtle, masked by media opacity, or difficult to assess clinically.
Methods
This prospective case series included patients with blunt or penetrating anterior segment trauma after repair examined at Watany Eye Hospital and the Watany Research and Development Center. All patients underwent full ophthalmic evaluation, including visual acuity, slit-lamp examination, and intraocular pressure measurement when feasible. Ultrasound biomicroscopy was performed using a 35 MHz probe with an immersion technique to assess the cornea, angle, iris, ciliary body, lens position, zonular status, and detect foreign bodies. Surgical findings and postoperative outcomes were correlated with UBM results when applicable.
Results
UBM enabled high-resolution visualization of anterior segment structures and revealed occult pathology not detectable on slit-lamp examination or on other imaging modalities that require clear media. It accurately identified the extent of zonular damage, cyclodialysis clefts, angle recession, and hidden foreign bodies. Precise localization and measurement of anterior segment foreign bodies significantly facilitated surgical planning and safe removal.
Conclusions
Ultrasound biomicroscopy is a powerful and indispensable tool in the evaluation of anterior segment trauma. By revealing hidden injuries and clarifying structural damage, it transforms uncertainty into actionable insight, directly guiding treatment decisions and optimizing surgical planning for better patient outcomes.
