Abstract:
Objective To investigate the factors associated with vision and hole closure for idiopathic macular hole (IMH) after vitrectomy surgery.Methods Eighty-nine eyes of 89 patients with IMH were enrolled in this retrospective study.There were 15 males and 74 females.The patients aged from 42 to 82 years,with the mean age of (64.13 ± 7.20) years.All subjects underwent best corrected visual acuity (BCVA) and optical coherence tomography (OCT) examinations.The BCVA ranged from 0.01 to 0.4,with the mean BCVA of 0.12 ± 0.09.The MH stages was ranged from 2 to 4,with the mean stages of 3.56 ± 0.77.The basal diameter ranged from 182 μm to 1569 μm,with the mean basal diameter of (782.52± 339.17) μm.The treatment was conventional 25G pars plana vitrectomy combined with phacoemulsification and intraocular implantation.Fortyone eyes received internal limiting membrane peeling and 48 eyes received internal limiting membrane grafting.The follow-up ranged from 28 to 720 days,with the mean follow-up of (153.73 ± 160.95) days.The visual acuity and hole closure were evaluated on the last visit and the possible related factors were analyzed.Results On the last visit,the BCVA ranged from 0.02 to 0.8,with the mean BCVA of 0.26±0.18.Among 89 eyes,vision improved in 45 eyes (50.56％) and stabled in 44 eyes (49.44％).Eighty-six eyes (96.63％) gained MH closure but 3 eyes (3.37％) failed.By analysis,patients of early stages of MH and smaller basal diameter of MH will gain better vision outcome (t=2.092,2.569;P＜ 0.05) and patients of early stage MH will gain high hole closure rate after surgery for IMH (t=-5.413,P＜0.05).However,gender,age,duration,preoperative BCVA,surgery technique,gas types and follow-up time had no relationship with the effect after surgery for IMH (P＞0.05).Conclusions Stages of MH and basal diameter of MH may be the factors associated with the visual outcome for idiopathic macular hole after surgery.However,age,gender,duration,surgery patterns,gas types and followup time showed no effects on operational outcomes.
