The Frequency of Fibrillopathia Epitheliocapsularis (So‐called Senile Exfoliation or Pseudoexfoliation) in Patients With Open‐angle Glaucoma

In this study we evaluated the frequency of pseudoexfoliation syndrome, the percentages of glaucoma and senile cataract in patients with and without pseudoexfoliation syndrome, and the percentages of pseudoexfoliation syndrome in patients with glaucoma and senile cataract in the Eastern Mediterranean area of Turkey. We examined 1356 persons over 40 years of age. Frequency of pseudoexfoliation syndrome in the greater than or equal to 50 years old age band was 7.2%, and there was a statistically significant difference between the sexes. Over 60 years of age, the frequency of pseudoexfoliation syndrome was 11.2%, the percentage of glaucoma in patients with pseudoexfoliation syndrome was 34.3%, the percentage of pseudoexfoliation syndrome in patients with glaucoma was 46.9%, the percentage of cataract in persons with pseudoexfoliation syndrome was 88.1%, and the percentage of pseudoexfoliation syndrome in persons with cataract was 17.7%. The differences between the percentage of glaucoma and cataract in patients with and without pseudoexfoliation syndrome, were both statistically significant (p less than 0.001).

“…This is close to unselected materials in which the reported incidence for subjects over 60 was 4.0-6.3 O/O (Aasved 1969). The corresponding frequencies among the relatives of patients with pseudoexfoliation were 8 and 14 O/o.…”

Studies on Relatives of Patients With Glaucoma Simplex and Patients With Pseudoexfoliation of the Lens Capsule

Pohjanpelta¹,

Hurskainen²

1972

The occurrence of glaucoma and pseudoexfoliation of the lens capsule was investigated in 185 relatives, aged over 40, of patients with glaucoma simplex, glaucoma capsulare and normotensive pseudoexfoliation. The aggregate frequency of glaucoma and suspected glaucoma in the first group was 49, in the middle group 33 and the last group 9O/o. Pseudoexfoliation of the lens capsule was seen in 3 O i o of the glaucoma simplex relatives and 8 O / o of the pseudoexfoliation relatives. The genetic aspects of the findings are discussed.

“…In every age group, our incidence figures are higher than those for the said three countries. It may be mentioned for comparison that in Norway the age group 80-89 years had an incidence of 7.6 O/O (Aasved 1971), against the respective incidence of 32.8 O/O in Finland. Since Aasved's and the present studies describe the incidence of pseudoexfoliation among the inmates of old people's homes, the results, in our opinion, are comparable, and they must be interpreted as showing that the incidence of pseudoexfoliation in Finland really is higher than in the countries studied by Aasved.…”

Pseudoexfoliation of the Lens Capsule and Liberation of Iris Pigment

Krause

Forsius

1973

A total of 220 inmates of old people's homes, all over 60 years of age, were examined for pseudoexfoliation of the lens capsule. The incidence recorded for the age group 60-69 years was 10°/o, 70-79 years 21.3O/o and 80-89 years 32.8 "/a. The intraocular tension of the eyes with pseudoexfoliation averaged 17.5 mmHg, against an average of 15.4 mmHg in normal eyes. After mydriatics, pigmented floaters were seen in the aqueous humour of 61.5 O / o of the normal eyes, and 83.3 "/o of the eyes with pseudoexfoliation. In these latter eyes, moreover, the pigment liberation was distinctly more marked. The trabecular region of the affected eyes was more pigmented than that of the normal eyes. The mechanism by which pseudoexfoliation possibly affects pigment liberation and trabecular pigmentation is discussed.
