[Potential association of pseudoexfoliation syndrome (PEX) with age-related macular degeneration (ARMD)].
OBJECTIVE
Authors report an unexpected association between PEX and ARMD. It was an additional result of a study, that analysed possible systemic symptoms of pseudoexfoliation material in visceral organs. They reviewed literature data for both, concerning epidemiology and physiopathogeny.


METHODS
We conducted an age-and sex matched study of 142 patients in Brittany, 71 PEX and 71 controls, 31 men and 40 women in the 2 groups. The statistical study was performed with Epi Info 6.0 software using the X2 of Mantel-Haenszel Test.


RESULTS
Statistical positive relation was found between PEX and ARMD (p=0.02), both increasing with age.


CONCLUSIONS
Part of epidemiology seems to be similar in PEX and ARMD, especially environment role (particularly solar radiations), individual factors, and genetic predisposition. For the first time, in may 1999, a genetic localization of PEX was discovered on the chromosome II, and nearly of one loci of ARMD multiple localizations.
