Abstract: | Purpose. To evaluate the peripapillary RNFL (p-RNFL) thickness changes after vitrectomy for epiretinal membrane (ERM). The relationship between p-RNFL thickness change and visual function was assessed. Methods. Thirty-five eyes from 35 patients with ERM who underwent vitrectomy with internal limiting membrane (ILM) removal were included. Average p-RNFL and the four quadrants thickness were measured by spectral-domain optical coherence tomography (SD-OCT) before and at one, three, and six months after surgery. Results. At six months after surgery, p-RNFL thickness of the temporal and inferior quadrant was decreased in the operated eyes compared with fellow eyes (p<0.05). Pattern standard deviation (PSD) was higher than that of fellow eyes (p = 0.002). The temporal and inferior quadrant p-RNFL thickness showed a relationship with both best-corrected visual acuity (BCVA) outcome and the six-month PSD (p<0.05, respectively). Conclusions. The selective decrease in the temporal and inferior p-RNFL thickness after vitrectomy for ERM removal could indicate inner retinal damage related to ILM peeling. |
