Ultrasound biomicroscopy in diagnosis of anterior segment pathology
Summary
Purpose
To demonstrate the role of ultrasound biomicroscopy (UBM) for the diagnosis of anterior segment pathology.
Methods
UBM was performed in 7 patients with corneal opacity (6 eyes) and with anterior chamber (AC) opacity (1 eye).
Results
In first case with total hyphema UBM demonstrated thickening of the iris. Second case with post-contusional corneal edema and hyphema demonstrated signs of iridodialysis and cyclodialysis. Third patient with central corneal scar had a signs of intraocular epithelial proliferation. With UBM the epibulbar cyst extension into anterior chamber was confirmed in fourth clinical case. In patient with fungal corneal ulcer (fifth case) UBM demonstrated central corneal defect and anterior chamber opacities. Lipodermoid was found in sixth clinical case. UBM helped to confirm that the sclera was not involved. In seventh case with corneal nebula after ocular burns UBM demonstrated iridocorneal adhesion and retrocorneal fibrous membrane. UBM results in all clinical cases determined tactics of treatment.
Conclusions
UBM is a safe and effective diagnostic tool in the management of eyes with disorders of the anterior segment especially when visualisation is limited and multiple traumatic injures are involved.
