AIM:To demonstrate an improved surgical technique of whole piece consecutive internal limiting membrane(ILM) peeling without preservation of the epi-fovea to treat high myopic foveoschisis(MF).METHODS:A 23-gauge 3-port pars plana vitrectomy was performed on 16 patients with high MF.A parallel arc line along the vascular arcades was scraped out with a curved membrane scraper DSP.Next,an ILM forceps was used to catch hold of the incisal edge of the ILM flap,and the action of releasing and separating was subsequently taken toward the direction of the macular fovea.Next,the ILM forceps was used to grasp the released area,and the whole area coherent ILM peeling covering the macular fovea was implemented thereafter.Finally,the ILM was folded backwards and peeled off in the arc direction.RESULTS:At the final visit,the average central macular thickness decreased remarkably from 423.76±177.67 to 178.24±66.21 μm.The mean logarithm of the minimum angle of resolution best-corrected visual acuity of 1.37±0.59 was significantly alleviated to 0.74±0.59.CONCLUSION:The wide range of whole piece consecutive ILM peeling without preservation of the epifovea is proven to be effective and significantly reduced the occurrence of retinal tear and macular hole.
