Exfoliation Syndrome

Abstract

In Norway we are not fully satisfied with the results obtained in our chronic open-angle glaucoma treatment. This may be due to the fact that 80% to 90% of our "primary" open-angle glaucomas also exhibit exfoliation syndrome ("pseudoexfoliation of the lens capsule").^1-3As suggested by Vogt,⁴this type of glaucoma may be called glaucoma capsulare. It is usually classified as a secondary glaucoma, as exfoliative substance has been demonstrated in the intratrabecular spaces, probably interfering with the drainage of aqueous humor causing rise in intraocular pressure.^5,6A difference in trabecular meshwork pigmentation is found between primary open-angle glaucoma and glaucoma capsulare eyes, the latter being more heavily pigmented.^7,8A recent study by Tarkkanen⁹indicates that a difference also may exist in prognosis. It is well known that the incidence of exfoliation syndrome in patients with "primary" open-angle glaucoma is reported differently in different countries; ranging
