• Purpose: The aim of this study was to evaluate the optical coherence tomography angiography (OCTA) features of patients who underwent successful macular hole (MH) surgery. Methods: Nineteen patients who underwent surgery in a single eye due to MH and 13 healthy subjects as a control group were included in the study. Vascular densities, flow indexes, and the foveal avascular zone (FAZ) area in superficial and deep retinal capillary plexuses were evaluated by OCTA in the right eyes of the control group, and both the surgical and healthy fellow eyes of the patients. Results: The mean vascular densities of the superficial and deep capillary plexuses were significantly lower in the surgical eyes than in the control group (44.1 vs. 49.6%, p = 0.002, and 47.3 vs. 59.1%, p = 0.009, respectively). The mean superficial and deep capillary flow indexes were significantly lower in the surgical eyes than in the control group (0.85 vs. 1.35, p = 0.003, and 0.57 vs. 1.45, p = 0.001, respectively), while the mean superficial and deep FAZ area were significantly greater in the surgical eyes in comparison to the control group (0.55 vs. 0.32, p < 0.001, and 0.64 vs. 0.37, p = 0.001, respectively). There was no difference between the flow indexes of both layers of the healthy fellow eyes and the control group. Conclusions: These preliminary results may be an explanation for unsatisfactory visual gain after surgery, despite the successful anatomical closure of the MH.
