Objective To observe the macular structure changes and its relationship with visual function in patients with idiopathic macular hole (IMH). Methods Forty-seven patients (47 eyes) with IMH who underwent pars plana vitrectomy were enrolled in this study. All patients were examined including bestcorrected visual acuity (BCVA), slit-lamp microscopy, indirect ophthalmoscopy, B-scan ultrasonography, optical coherence tomography (OCT) and MP-1. All the patients underwent a standard three-port pars plana vitrectomy. The BCVA, mean light sensitivity (MS) in macular area, macular hole diameter, the photoreceptor inner and outer segment (IS/OS) junction defect, external limiting membrane (ELM) defect were observed on the 1st, 3rd and 6th months after surgery, and then the relationship of IS/OS junction defect, ELM defect, sensitive and BCVA were analyzed. Results The 1st, 3rd and 6th months after surgery, the logarithm of minimal angle of resolution (logMAR) BCVA (t=16.4, 35.7, 20.7; P<0.05) and MS (t=-13.8, -17.9, -2.5; P<0.05) were improved significantly; the macular hole diameter (t=7.7, 7.7, 7.7;P<0.05), IS/OS junction defect (t=24.1, 19.3, 27.4; P<0.05) and ELM (t=20.5, 6.7, 15. 8; P<0.05) defect were decreased significantly. Preoperative IS/OS junction defect and ELM defect were both related to sensitive (r=-0.55, -0.53; P<0.05), but uncorrelated with BCVA (r=0.13, 0.13; P>0.05). IS/OS junction defect and ELM defect 1st, 3rd and 6th months after surgery were both related to MS and BCVA (P<0.05). Conclusions The logMAR BCVA and MS increases, while IS/OS junction and defect ELM defect decreases after surgery in IMH patients. IS/OS junction defect and ELM defect after surgery were both related to sensitive and BCVA.
