  • Look Inside

We evaluated the morphological features of the ciliary body in 33 eyes with narrow chamber angle using an ultrasound biomicroscope, UBM. The ciliary body was in apposition with the posterior iris surface in 26 eyes, 88%. A similar apposition was present in 3 of 9 normal eyes (33%) and in 2 of 7 eyes with primary open angle glaucoma (28%) . This apposition was more pronounced in eyes with shallow anterior chamber of less than 2.20mm. The observed finding suggests that anterior displacement of the iris root by the ciliary body may be one of the causative factors of narrow chamber angle in Japanese eyes.
