Objective To investigate the visual function of idiopathic macular hole before and after macular surgery. Methods Vitreous-retinal surgery was performed in 19 patients(19 eyes) with idiopthic macular hole.Among them,3 eyes belonged to stage 2，10 eyes stage 3 and 6 eyes were stage 4. The visual function including international standard visual acuity,laser retinal visual acuity,photopic ERG intensity responses- and Humphrey 30 deg;-2 visual field were tested and compared before and after the surgery. Results (1)International standard visual acuity was from 0.01 to 0.1 preoperatively,and from 0.04 to 0.4 post operatively,the difference was not significant(P＞0.0 5).(2)Laser retinal visual acuity was from 0.12 to 0.4 preoperatively,and from 0.2 to 0.63 postoperatively,the difference was significant (P＜0.05).(3)In photopic ERG intensity responses:the Log K value of bwave decreased after surgery (P＜0.05),but no obvious change found in Rmax and n Value after operation.(4)Humphrey visual field examination revealed the thresholds for 0-10 deg; increased after surgery(P＜0.05),but not obvious for 15-30 deg;． Conclusion The visual function of the macular cones are increased by macular surgery for IMH.
