Ultrasound biomicroscopic features of iris retraction syndrome.
OBJECTIVE
To examine anatomic relationships of anterior and posterior chamber structures in iris retraction syndrome using ultrasound biomicroscopy.


METHODS
Four eyes of four patients with iris retraction syndrome were imaged using high-frequency, high-resolution, anterior segment ultrasound biomicroscopy. In two patients, scans were obtained before and after medical therapy.


RESULTS
Three patients presented with iris retraction configuration and one with iris bombe. In the latter case, iris bombe converted to iris retraction and back to iris bombe with the administration and later withdrawal of aqueous suppressants. Ciliochoroidal effusion was present in all eyes.


CONCLUSIONS
Ciliochoroidal effusion is a constant feature of iris retraction syndrome. The hypotony associated with this disorder may result in part from aqueous hyposecretion related to ciliary body detachment. Ultrasound biomicroscopy is a useful aid in the diagnosis and follow-up of eyes with iris retraction syndrome.
