(Pseudo)exfoliation Syndrome (2564 words) |
 | In a Finnish population, exfoliation syndrome was found in 10% of patients aged 60 to 69, 21% of those aged 70 to 79, and 33% of those aged 80 to 89.26 In a Finnish screening, Rouhiainen and Ter=E4svirta66 found exfoliation syndrome in either eye of 8.5% of 65-year-olds and 13.2% of 75-year-olds. |
| Exfoliation material appears to be produced by the equatorial lens epithelium, iris pigment epithelium, and non-pigmented ciliary epithelium.11,13,139,202,207,212,304-309 At these locations, it is commonly found within epithelial cells in association with abnormal basement membrane.310 The lens capsule itself appears normal, although it may contain amorphous material. |
| The exfoliation material on the surface of the lens is believed to result partially from deposition of material produced by the iris and ciliary body and partially from material produced by the lens epithelium which passively diffuses through the anterior lens capsule. |
