Sato T, Mori R, Takahashi S, et al. - In eyes with epiretinal membrane (ERM) after surgery, researchers studied the anatomical and functional changes in areas containing paravascular abnormalities (PVA). The study sample consisted of 28 eyes with concurrent idiopathic ERM and PVA. Postoperatively, best-corrected visual acuity and central macular thickness have been improved significantly. According to this prospective study, after ERM surgery, PVA improves not only anatomically but functionally. Vitrectomy can enhance retinal sensitivity in PVA areas as well as central vision.
