Serous retinal detachment with retinal pigment epithelium tear after PreserFlo MicroShunt surgery: a case report

This is the first reported case of RPE tears and serous retinal detachment following Preserflo MicroShunt surgery. These findings highlight that a rapid and significant reduction in IOP, even without reaching absolute hypotony, might disrupt choroidal circulation and RPE integrity, particularly in eyes with predisposing factors, such as atopic dermatitis and long-term steroid use. Early recognition of CD and timely intervention to elevate IOP are crucial for preventing vision-threatening complications.
