Cases of Pseudophakic Pseudoexfoliation in Glaucoma Patients

We present cases of primary open angle glaucoma patients without previous history of pseudoexfoliation who developed pseudoexfoliative materials on the anterior surface of the intraocular lens after cataract surgery. Among 5 unilateral pseudophakic pseudoexfoliation cases, 3 showed a more advanced state of glaucoma in the affected eye. The other 2 cases showed progression of glaucoma in the affected eye after the development of pseudophakic pseudoexfoliation, while the unaffected eyes remained stable. In the latter 2 cases, control of intraocular pressure was difficult, and more glaucoma medication was needed in the affected eye. Pseudophakic pseudoexfoliation in glaucoma patients with no history of pseudoexfoliation syndrome or pseudoexfoliative glaucoma has not been reported. In our cases, the eyes which developed pseudophakic pseudoexfoliation showed a more advanced state of glaucoma, more difficulty controlling intraocular pressure, and faster progression of glaucoma. More observation is needed, but we cautiously postulate that pseudophakic pseudoexfoliation may have a role as a clinical risk factor in the prediction of glaucoma progression.
