Objective:
To investigate the relation of the visual function recovery and the postoperative form of the idiopathic macular holes.
Methods:
38 eyes with macular holes which were closed after one surgery were selected and were grouped into type of complete healed, partial healed and no healed by Optical Coherent Tomography (OCT). Scanning Laser Ophthalmoscope (SLO) examination were performed preoperatively and 1 month, 3 months and 6 months postoperatively to detect the sensitivity, areas of absolute scotoma, relative scotoma and central visual acuity.
Results:
Among type of complete healed group and type of partial healed group 6 months after vitrectomy the central vision, sensitivity, areas of absolute scotoma and relative scotoma had statistical significant improvement. The central vision and sensitivity improved postoperatively and areas of absolute scotoma and relative scotoma had no significant changes in type of no healed group. The extent of improvement of vision, sensitivity, absolute scotoma in type of complete healed group was more greater than type of partial healed group and no healed group. The fovea configuration of stage II macular holes was easier to recover completely.
Conclusions:
The recovery of the normal curvature of macular fovea is positive to the improvement of the visual function. The better the fovea contour recover, the more significantly the visual function improve. The early stage of macular holes (stage II) could get better improvement of visual function.
