Fixation point after successful macular hole surgery with internal limiting membrane peeling.

摘要

BACKGROUND AND OBJECTIVE: This study evaluated the fixation points of macular holes using scanning laser ophthalmoscope microperimetry before and after surgery with internal limiting membrane peeling. PATIENTS AND METHODS: This prospective non-comparative study examined 21 eyes (21 patients) with macular holes. Hole size and distance between preoperative and postoperative fixation points were measured. RESULTS: The fixation points were located on the superior edge of the macular hole in 18 (86%) cases preoperatively and shifted centrally in 15 (71.4%) cases postoperatively. Macular hole size correlated well with the distance moved by the fixation points (r = .83, P < .0001). CONCLUSION: Scanning laser ophthalmoscope microperimetry facilitated pinpointing of fixation points before and after surgery. The correlation between macular hole size and fixation point shift suggests that the retina around the hole moves centripetally after surgery.
