Pachychoroid refers to an anatomic choroidal characteristic with abnormally thick choroid or abnormally dilated Haller's vessels. Pachychoroid can range from mild forms which does not cause any problems to more serious ones that might cause vision loss.This study will recruit participants with pachychoroid, to learn more about how this condition develops, how it affects people in the long run, and what factors might make it worse.",[93],"Pachychoroid Disease","2026-06-10",{"date":96,"type":97},"2026-06-12","ACTUAL",{"date":99,"type":97},"2025-03-04",{"date":101,"type":89},"2029-08",{"name":5,"class":6},4]
