Abstract
Objective To evaluate the significance of multifocal electroretinography(mERG) before and after surgery of vitreous macular traction syndrome(VTS)for restoration of macular function. Methods Eleven eyes of 11 cases with VTS were collected.Before and after vitrectomy the mERG examinations were performed and the changes of central macular retinal amplitude response density were analyzed and compared. Results The follow-up time was 6 months, the difference of macular fovea retinal amplitude response density was statistically significant between before and after surgery(t=3.320, P=0.005). After surgery, the central macular retinal amplitude response density increased and the function of macular area gradually restored. Conclusion After VTS, the central macular retinal amplitude response density increase and the function of macular area gradually is restored. Key words: Vitrectomy; Syndrome, traction, vitreous, macular
