[Pseudoexfoliation syndrome].
The Frequency of the Pseudoexfoliation-Syndrom (= PES) was investigated about two months in a prospective study of 1069 patients in the university eye hospital of Zurich. 7.35% of these patients had a PES with or without glaucoma. Among the clinic patients there were 9.9% and among the policlinic patients 6.26%. All our patients were elder than 60 years old, 58.9% between 70-85 years. There were 33.37% men and 66.63% women. 33% of the PES-patients had a tension over 22 mmHg. 42.86% of the patients had the highest tension over 30 mmHg. 33.33% (= 26 patients) had a PES without glaucoma and 66.66% (= 52 patients) a PES with glaucoma. 56.42% of the patients (= 44 patients) had in one eye PES and 43.58% (34 patients) in both eyes. 9.61% (= 5 pat.) had an absolute PES-glaucoma in one eye.
