Brief summary

This study aims to evaluate the central foveal thickness and visual outcomes of the standard internal limiting membrane (ILM) peeling technique in comparison with the ILM abrasion technique in the primary epiretinal membrane (ERM) surgery. The hypothesis was that abrasion of the ILM with a diamond-dusted membrane scraper at ERM surgery may be more effective than the standard ILM peeling technique in terms of visual acuity and CRT.

Interventions

- Historical patient records from Ankara Ulucanlar Eye Training and Research Hospital between 2/01/2014 and 30/09/2018 were reviewed. - Patients who underwent epiretinal membrane (ERM) surgery with inner limiting membrane (ILM) peeling were included in the study. - While one of the surgeons (M. Citirik) performed the AIP technique, the other surgeon (MY. Teke) performed the SIP technique, where each surgery takes around one hour. - In AIP Technique, after the dye aspiration, a diamond-dusted membrane scraper (DMSS, Dorc, Dutch) was brushed over the macula within an area of two-disc diameter surrounding the ERM. Initially, a flap was created using a gentle sweep of a diamond-dusted membrane scraper across the ILM surface. To avoid formation of irregular abrasions and tearing of underlying tissue, DDMS was gently angled with its more rounded surface exposed along the tip’s exterior angle when brushing the ILM. - The optical coherence tomography (OCT) images were examined by a retina specialist who was masked to the patient and visual acuity outcomes. Retinal architecture and central retinal thickness (CRT) measurements were evaluated with the OCT.
