Purpose: To evaluate the incidence, associated factors, and outcome of persistent subretinal fluid (SRF) after vitrectomy for macular hole-associated retinal detachment (MHRD).
Methods: A total of 158 eyes from 156 patients with MHRD who achieved macular hole closure after primary vitrectomy were included in the analysis; persistent SRF was defined as the presence of SRF for more than 1 month after first surgery. Preoperative and postoperative parameters were analyzed for their relationship with SRF development.
