Case in brief
A patient presented with phacolytic glaucoma associated with traumatic lens subluxation, a combination that can be difficult to distinguish from other lens-induced glaucomas. Ultrasound biomicroscopy (UBM) showed a subluxated, thinned lens with open angles, cortical liquefaction, and zonular insufficiency. The patient underwent phacoemulsification with capsular tension ring implantation. At 1-month follow-up, visual acuity was 20/20 and intraocular pressure had normalized.
What made this case unusual
The combination of phacolytic glaucoma and traumatic lens subluxation posed a diagnostic challenge; UBM demonstrated the lens and zonular findings despite limitations of conventional imaging.
Diagnostic / clinical pearl
In suspected lens-induced glaucoma with traumatic lens subluxation, UBM can clarify lens position, cortical liquefaction, zonular integrity, and angle status to support diagnosis and surgical planning.
