What's the Choroid Got to Do With Angle Closure?

Arch Ophthalmol. 2009;127(5):693-694. doi:10.1001/archophthalmol.2009.80

Angle-closure glaucoma (ACG) is often considered to be a simple disease that is cured by laser iridotomy. However, recent studies with new imaging modalities are providing insights into the more complex nature of ACG. Kumar and colleagues1 at the Singapore National Eye Center confirm previous reports2-4 that eyes with primary angle closure can demonstrate abnormal separations between the choroid and sclera on ultrasonic biomicroscopy (UBM). These findings are consistent with the hypothesis that expansion of the choroid contributes to the development of primary angle closure in some eyes.
