Purpose:
To evaluate the surgical outcome of retinal reattachment, the reattachment rate according to the range of detachment, and postoperative visual acuity for macular hole retinal detachment (MHRD).
Subjects And Methods:
Sixty-eight eyes of 67 patients with MHRD were analyzed. The mean follow-up period was 54 months.
Results:
Retinal reattachment occurred in 42/68 eyes (62%) after initial surgery. The reattachment rates were 6/23 eyes (26%) in the gas tamponade group, 13/19 eyes (68%) in the vitrectomy group, 23/ 26 eyes (88%) in the group that underwent removal of internal limiting membrane as adjunct to vitrectomy (ILM) group. In the additional surgery, the reattachment rates were 5/9 eyes (56%) in the gas tamponade group, 13 eyes (100%) in the vitrectomy group, 1/2 eyes (50%) in the ILM group, and 6 eyes (100%) in the macular prombe buckling group. No significant differences were seen in the detachment extent-related reattachment rate within the same surgery and the postoperative visual acuity between the groups.
Conclusion:
The results show that removal of ILM contributes to successful reattachment in the initial surgery, and that for non-reattachable eyes, macular buckling in the second surgery is the most reliable method.
