Ultrasound biomicroscopy in the diagnosis and management of intraocular gnathostomiasis.
OBJECTIVE
To describe the use of ultrasound biomicroscopy in the identification of an intraocular nematode in a case of suspected nematode-induced uveitis


METHODS
Observational case report.


METHODS
UBM was performed under topical anesthesia in a patient with acute painful uveitis suspected to result from an intraocular nematode. Clinical examination did not reveal the nematode.


RESULTS
Over a 6-minute time span, serial UBM examinations revealed the nematode to move from the iris root into the posterior chamber through the zonules. Subsequently, it was seen adhering to the cornea and could be removed surgically, resulting in symptom relief.


CONCLUSIONS
UBM is a useful tool in diagnosis and management of parasitic uveitis.
