Purpose: To evaluate long-term outcome after revitrectomy with autologous platelet concentrate (APC) or whole blood (WB) in persistent idiopathic macular hole (MH) after vitrectomy with internal limiting membrane (ILM) peeling. Procedures: Retrospective study of 75 eyes with persistent MH after vitrectomy with ILM peeling and gas. All patients underwent revitrectomy with gas and APC (n = 61) or WB (n = 14). Main outcome measures were anatomical closure rate and postoperative best-corrected visual acuity (BCVA). Results: Closure rate after revitrectomy was 85.2% (52/61) in the APC group and 7.1% (1/14) in the WB group. Median follow-up was 58 (range 3-147) months. Median BCVA (logMAR) in patients with finally closed MHs was 0.4 ± 0.3. Patients with defects of the ellipsoid zone had significantly worse postoperative BCVA. Morphological MH configuration (atrophic or elevated edges) did not correlate with final closure rate. Conclusions: Revitrectomy with APC and gas is a very effective treatment in persistent MH after vitrectomy with ILM peeling and gas.
