PURPOSE
To evaluate the relation between recovery of visual function and microperimetric fixation area in eyes with idiophthic macular hole after vitrectomy. METHODS: We used SLO (Scanning laser microscope, Rodenstock, Germany) microperimetry to examine foveal retinal function and fixation area in 14 eyes with idiopathic macular hole following pars plana vitrectomy. The relation between those preoperative and postoperative best corrected visual acuity and fixation area was studied. RESULTS: The macular hole size was correlated with preoperative visual acuity (p=0.026) and the closure of hole was related to the size of fixation area (p=0.003). The postoperative visual acuity was related to symptom duration before the vitrectomy (p=0.03), but not related to preoperative macular hole size. The fixation area correlated with the postoperative best corected visual acuity (p=0.043) and the direction of movement was variable. In most eyes, fixation area was located above the horizontal meridian. CONCLUSIONS: The fixation area was correlated with postoperative visual acuity and we think functional macular hole closure as well as anatomical closure were useful parameter of the success of macular hole surgery. |
