“…This is lower than previously reported incidence rates, which range from 13.6% to 24.2% [6, 22, 23, 26]. One reason for this divergence may be differences in both ERM severity and duration of time since ERM onset.…”

ObjectiveTo investigate the occurrence ratio, localization, and surgical outcomes of intraretinal cystic spaces in idiopathic epiretinal membranes (ERMs).MethodsWe retrospectively reviewed the charts of 432 eyes of 398 consecutive patients with idiopathic ERM who underwent vitrectomy and ERM peeling from January 2012 to September 2015. We selected cases with intraretinal cystic space prior to surgery, detected by spectral-domain optical coherence tomography. We then evaluated the effects of ERM peeling on intraretinal cystic spaces, best corrected visual acuity, and central retinal thickness at 6 months after surgery.ResultsTwenty-four eyes (5.5%) showed intraretinal cystic spaces before surgery, present in the inner retinal layer (the inner group) in 9 eyes, in the outer retinal layer (the outer group) in 6 eyes, and in both the inner and the outer retinal layers (the combined group) in 9 eyes. Additionally, 30 eyes with ERM but without any presence of intraretinal cystic space were selected randomly and classified as the no cyst group. At 6 months after surgery, the disappearance rate of cystic spaces was significantly greater for the outer group than for the inner group (83.3% and 11.1%, respectively, P = 0.011). The mean best corrected visual acuity improved significantly after surgery in the inner group, the outer group, and the no cyst group (P < 0.05 for all three groups) but did not improve in the combined group (P = 0.58). The mean central retinal thickness decreased significantly after surgery in the inner group, the combined group, and the no cyst group (P < 0.05).ConclusionsIntraretinal cystic spaces were observed in 5.5% of preoperative idiopathic ERM cases. Following surgery, the cystic spaces in the outer retinal layer disappeared at higher rates than those in the inner retinal layer, suggesting that the pathophysiologies of these cystic spaces are different.

“…Combined surgery was performed with phacoemulsification and IOL implantation immediately prior to vitrectomy by the same anterior segment surgeon (MK). A macular OCT image was obtained preoperatively using the Zeiss Stratus OCT unit (Carl Zeiss Meditech, Dublin, California, USA) 12. Biometry measurements were taken preoperatively using the Eye Cubed ultrasound system (Ellex, Eden Prairie, Minnesota, USA).…”

Purpose To correlate the frequency and extent of simultaneous inadvertent internal limiting membrane (ILM) peeling during idiopathic epiretinal membrane (ERM) removal with characteristics of ERM adherence demonstrated on pre-operative spectral domain optical coherence tomography (SD-OCT). Patients and methods This is a prospective, observational, case series of patients undergoing pars plana vitrectomy for idiopathic ERM. Inner retina-ERM adhesion was categorized as focal, broad or complete in five anatomic locations at macular area based on preoperative SD-OCT findings. The extent of spontaneous ILM peeling was quantified on a scale 0-100% in each of the aforementioned anatomic locations by the operating surgeons who were masked to the OCT characteristics. All operations were recorded with a high definition recording system and the area of simultaneous ILM peel was quantified by a second masked observer. The final extent of spontaneous ILM peel was calculated as the average of the two scores. Results Thirty consecutive subjects who underwent surgery for idiopathic ERM were included in the study. Evidence of simultaneous ILM peeling was identified in 80.3% of individuals. With regards to the type of ERM-macula adhesion, inadvertent ILM peel was observed in 70% of the patients who pre-operatively showed complete adhesion, in 43% with broad adhesion and in only 21% with focal adhesion (Po0.001). The extent of the spontaneous ILM peel during removal of ERM was also significantly dependent on the type of ERM-inner retina adhesion. Total simultaneous ILM peel was observed in 59% of locations with complete ERM-macula adhesion but only in 22% and 7% of locations with broad and focal adhesion respectively (Po0.001). Conclusions Simultaneous ILM peel is a frequent occurrence during ERM surgery, especially when there is complete or broad ERM adherence to the macula. The type of ERM-inner retina adhesion represents a valid predictor of the extent of simultaneous ILM peel during removal of ERM. Thorough evaluation of preoperative OCT may be a useful tool in determining a safer, more simplistic strategy in ERM surgery.
