Cystoid macular edema after pars plana vitrectomy for retained lens fragments

To describe the incidence and clinical course in patients with cystoid macular edema (CME) following pars plana vitrectomy (PPV) for retained lens fragments.

Retina group, private practice.

This retrospective study reviewed the medical records of 91 patients who had PPV for retained lens fragments. The patients were followed for at least 6 months. Patients with concomitant eye diseases that adversely affected macular examination or macular function were excluded.

Four (8%) of 50 eyes with a sulcus-fixated posterior chamber intraocular lens (PC IOL) implanted at cataract extraction and 19 (46%) of 41 eyes with aphakia or an anterior chamber IOL developed CME (P

Sulcus placement of a PC IOL at cataract extraction was associated with a reduced risk for CME. The prognosis for eyes that develop CME after PPV for retained lens fragments is guarded. Long-term therapy should be considered because of the high rate of recurrence.
