Changes in peripheral anterior chamber depth of a case of relapsing polychondritis with recurrent secondary angle closure glaucoma section sign.

A case of relapsing polychondritis showed IOP elevations three times during the follow-up due to the angle-closure mechanism. The peripheral anterior chamber depth (ACD) showed a good correlation with IOP elevation, but central ACD did not. The peripheral ACD could be more related to IOP elevation than central ACD.
