Objective To observe the changes of anatomic structure and visual function after surgery in highly myopia patients with macular hole and retinal detachment (MHRD). Methods Twentyfive patients (25 eyes) with MHRD who underwent vitreous and internal membrane peeling surgery combined with silicone oil tamponade, were enrolled in this study. All the patients had undergone the examinations of logarithm of minimal angle of resolution (logMAR) visual acuity, optical coherence tomography (OCT), MP-1 microperimetry and multifocal electroretinogram (mf-ERG) before and three months after surgery. The visual acuity, structure of macular hole and macula, fixation point, mean sensitivity (MS) within 10° of macular area and four quadrants including supertemporal, supernasal, intranasal and infratemporal, average response densities of N1 and P1 waves at all 6 rings before and after surgery were observed. Results Three months after surgery, the logMAR visual acuity improved (t=8.265， P＜0.05). Twentyfour eyes (96%) were anatomically reattached, one eye (4%) was not anatomically reattached completely. The results of MP-1 microperimetry showed that foveal fixation was found in two eyes (8%), weak foveal fixation was found in four eyes (16%), paracentral fixation was found in 19 eyes (76%). There were four eyes (16%) with stable fixation, nine eyes (36%) with relatively unstable fixation and 12 eyes (48%) with unstable fixation. The MS value within 10° of macular area was 9.031±4.245 dB. The MS value difference among four quadrants was statistically significant (F=7.40，P=0.015). The mf-ERG results showed that the average response densities of N1 and P1 waves at all 6 rings were increased (P＜0.05). Conclusion The macular hole heals, retina remains reattached, visual acuity, and fixation are improved in the most of MHRD eyes after surgery.
