Cumulative Incidence of Converting from Clinically Unilateral to Bilateral Exfoliation Syndrome

Abstract

A large proportion of patients with clinically unilateral ES will not convert to bilateral involvement in long-term follow-up. Immunohistochemical studies suggest that local factors must either expedite ES or slow it down in one eye to explain the frequently longstanding asymmetric involvement, and a difference in initial aqueous outflow facility might be examined as one candidate.
