Pigmentary glaucoma due to Soemmerring ring: A histopathologic study

We report a case of secondary pigmentary glaucoma due to Soemmerring rings in a patient with retinitis pigmentosa and describe the histopathologic findings. Unlike other cases of pseudophakic pigmentary glaucoma that are usually due to malpositioned intraocular lenses (IOLs) or bent haptics, this case had a well-positioned IOL in the capsular bag. The prominent Soemmerring ring appears to be the cause of the pigment release. Although Soemmerring rings have been associated with angle-closure glaucoma, they have not previously been shown to cause any form of open-angle glaucoma.
