Abstract:
Objective To evaluate metamorphopsia and vision-related quality of life (VRQoL) and its influencing factor after vitrectomy for idiopathic macular hole (IMH).Methods This is a prospective and nonrandomized clinical cohort study.Thirty eyes of 30 IMH patients who received vitrectomy and inner limited membrane (ILM) peeling were included.The best-corrected visual acuity (BCVA),medical refraction test and optical coherence tomography (OCT) were performed.BCVA was recorded as logarithm of the minimum angle of resolution (logMAR).The macular hole index (MHI) was measured using OCT.The average logMAR BCVA and MHI in suffering eyes at baseline were 1.02± 0.07 and 0.47 ± 0.02,respectively.The uncorrected visual acuity of the fellow eyes was less than 0.1.Follow-up period was longer than 6 months.At 6 months after surgery,the central retinal thickness (CRT) was measured by OCT;vertical and horizontal metamorphopsia were measured by metamorphopsia charts;VRQoL was evaluated by Chinese VRQoL-25.Spearman correlation analysis was performed to analyze the relationship of VRQoL and postoperative BCVA,metamorphopsia and preoperative MHI.Results At 6 months after surgery,macular hole closure was confirmed by OCT in all patients.The vertical and horizontal metamorphopsia were (0.17± 0.03)° and (0.11 ± 0.03)°,respectively.The VRQoL-25 composite score was 79.81 ± 1.29.The average BCVA was 0.59±0.05.The average CRT was (155.10± 6.27) μm.The postoperative VRQoL was positive correlated with preoperative MHI (r=0.491,P=0.002),and negative correlated with preoperative BCVA (r=-0.445,P=0.014),postoperative BCVA (r=-0.530,P=0.003) and postoperative metamorphopsia (r=-0.532,P=0.006),but not correlated with the postoperative CRT (r=0.231,P＞0.05).Conclusions IMH patients improved their visual acuity after surgery,but still have metamorphopsia.VRQoL was negative correlated with metamorphopsia,positive correlated with preoperative MHI.
