Eleven (28%) of 39 patients with glaucoma capsulare responded to topical dexamethasone treatment with pressure elevation of 6 mm Hg or more. It seems that glaucoma capsulare is not genetically identical with primary open-angle glaucoma and should be regarded as secondary glaucoma. Interestingly, most responders (eight out of 11) had, in addition to glaucoma capsulare in one eye, primary open-angle glaucoma in the fellow eye.
