The frequency of exfoliation syndrome was significantly higher in enucleated eyes from Finland than in eyes from Denmark, a study found. The study authors noted that their study confirms earlier studies indicating that exfoliation syndrome is rare in Denmark compared with other Nordic countries.
Ghassan Ayish Alyahya and colleagues at the University of Copenhagen compared the frequency of exfoliation syndrome in 304 eyes of Danish people and 240 eyes of Finnish people, all of which were enucleated because of absolute glaucoma. They also compared the rates of uveal melanoma in 39 enucleated eyes of Danish people and 149 enucleated eyes of Finnish people.
In eyes enucleated because of absolute glaucoma, exfoliation syndrome was found in 12 eyes from Denmark (3.9%) and in 16 eyes from Finland (41%). In the eyes with melanoma, exfoliation syndrome was found in two Danish eyes (0.8%) and in nine Finnish eyes (6%). The differences for both groups were statistically significant.
The study is published in the September issue of Acta Ophthalmologica Scandinavica.
