“…We recently reported a case that suggested a centripetal movement of the inner retinal layers from the movement of the vessel bifurcation points after ILM peeling. 16 We also found that a decrease in the size of the foveal avascular zone (FAZ) occurred postoperatively, as seen by optical coherence tomography angiography in Case 3. The decrease in FAZ area suggests that a centripetal movement of retinal layers occurs after ILM peeling.…”

PurposeTo report the findings in three cases in which the average foveal thickness was increased after a thin epiretinal membrane (ERM) was removed by vitrectomy with internal limiting membrane (ILM) peeling.MethodsThe foveal contour was normal preoperatively in all eyes. All cases underwent successful phacovitrectomy with ILM peeling for a thin ERM. The optical coherence tomography (OCT) images were examined before and after the surgery. The changes in the average foveal (1 mm) thickness and the foveal areas within 500 μm from the foveal center were measured. The postoperative changes in the inner and outer retinal areas determined from the cross-sectional OCT images were analyzed.ResultsThe average foveal thickness and the inner and outer foveal areas increased significantly after the surgery in each of the three cases. The percentage increase in the average foveal thickness relative to the baseline thickness was 26% in Case 1, 29% in Case 2, and 31% in Case 3. The percentage increase in the foveal inner retinal area was 71% in Case 1, 113% in Case 2, and 110% in Case 3, and the percentage increase in foveal outer retinal area was 8% in Case 1, 13% in Case 2, and 18% in Case 3.ConclusionThe increase in the average foveal thickness and the inner and outer foveal areas suggests that a centripetal movement of the inner and outer retinal layers toward the foveal center probably occurred due to the ILM peeling.

“…We have reported two cases that showed a decrease in the FAZ area and the papillofoveal distance after vitrectomy with ILM peeling for a VMT and thin ERM. 11 , 12 In this study, we compared the decrease of the FAZ area and papillofoveal distance with or without ILM peeling. A significant decrease in the FAZ area and papillofoveal distance was observed postoperatively only in the ILM-peeled eyes.…”

“… 1 , 5 , 8 Optical coherence tomography angiography (OCTA) was recently introduced as a noninvasive method that can obtain en face images of the capillary plexuses at different depths of the retina and choroid. 10 We have obtained OCTA images that showed a centripetal movement of identifiable capillaries toward the foveal center after vitrectomy with internal limiting membrane (ILM) peeling for a VMT 11 and for a thin ERM. 12 …”

PurposeThe aim of this study was to determine whether the centripetal displacement of the capillaries in the macular region after vitrectomy is caused by internal limiting membrane (ILM) peeling.MethodsEighteen patients with different types of retinal diseases but with a normal or approximately normal foveal contour underwent successful vitrectomy with (n=12) or without (n=6) ILM peeling. Optical coherence tomography angiography (OCTA) images of the inner retinal vascular plexus in the macular region were analyzed pre- and postoperatively. Four concentric polygonal areas were marked in the OCTA images with the corners selected to be easily identified by vessel bifurcations. The areas of the postoperative foveal avascular zone (FAZ) and the four polygonal regions at about 1 month postoperatively were compared to the baseline areas.ResultsVitrectomy was performed for eleven eyes with vitreomacular tractions, three with macular-on retinal detachments, and four with thin epiretinal membranes. A significant decrease in the FAZ area was observed postoperatively in only the ILM-peeled eyes (P=0.0002). The four polygonal areas in the ILM-peeled eyes decreased after surgery, and the decrease was fit by a linear regression line (R2=0.985–0.999; n=7). The time course of the postoperative decrease of the FAZ area was fit by a hyperbolic curve (R2=0.969–0.998; n=6). The average postoperative time required to reach one-half of the final FAZ area was 1.16 days (0.81–1.62 days).ConclusionThese findings suggest that ILM peeling causes an early centripetal displacement of the capillaries in the macular region.
