Two-Year Outcomes After Variable Duration of Drug Cessation in Patients With Maculopathy Associated With Pentosan Polysulfate Use.

The findings of this cohort study suggest that functional and structural deficits continue to progress in PPS-associated maculopathy even after drug cessation. Additional study is needed to determine whether these findings can be generalized to other patients with PPS-associated maculopathy and whether longer follow-up could determine subsequent disease course.
