Case report: The diagnostic and surgical value of UBM in phacolytic glaucoma secondary to traumatic lens subluxation.

This case report highlights the diagnostic and surgical value of ultrasound biomicroscopy (UBM) in managing phacolytic glaucoma with traumatic lens subluxation, a rare combination requiring differentiation from other lens-induced glaucomas. UBM precisely identified three pathognomonic features: (1) subluxated lens with reduced thickness yet open angles, (2) cortical liquefaction, and (3) zonular insufficiency, thus overcoming the limitations of conventional imaging modalities. The patient underwent successful phacoemulsification with capsular tension ring implantation, achieving 20/20 vision and normalized intraocular pressure (IOP) at 1-month follow-up.
