Combined exfoliation and pigment dispersion syndrome.
Both exfoliation syndrome and pigmentary dispersion syndrome can lead to secondary glaucoma. We treated five patients who had pigmentary dispersion and who subsequently developed exfoliation. In one patient who had bilateral pigment dispersion syndrome, the presence of exfoliation increased the difficulty of controlling intraocular pressure in the affected eye. In a monocular patient, exfoliation and pigmentary dispersion were concurrently present with characteristic defects of both pigmentary dispersion and exfoliation as seen by transillumination defects of the iris. A third patient had bilateral pigmentary dispersion and uncontrollable intraocular pressure in an eye with exfoliation. Despite argon laser trabeculoplasty, the pressure remained uncontrolled. Another patient had a filtering operation in the left eye, with gradually increasing intraocular pressure in the right eye. Exfoliation material complicated the pressure control in the unoperated on eye. Another patient had an eight-year history of glaucoma in the left eye for which filtering surgery was performed. Exfoliation was present in both eyes with controlled pressure in the filtered eye but uncontrolled pressure in the nonfiltered eye.
