Introduction: During macular hole (MH) formation, the vitreofoveal traction may lead to foveal neural tissue avulsion and consequent photoreceptor loss. However, the clinical significance of the photoreceptor outer segment disruption at the MH border remains unclear. This study aims to investigate the clinical features and surgical outcomes of MHs with photoreceptor outer segment disruption at the MH border. Methods: This study retrospectively reviewed 86 eyes from 85 patients who underwent vitrectomy combined with internal limiting membrane peeling for idiopathic MHs. Baseline and postoperative best-corrected visual acuity (BCVA) and foveal microstructure on optical coherence tomography images were compared between eyes with smooth and bumpy morphology, the latter of which was defined as those with an uneven and irregular surface with evident lumps and indentations at the MH border. Results: The bumpy morphology was identified in 59 of 86 eyes (68.9%). At baseline, eyes with a bumpy MH morphology had a significantly larger minimum linear diameter (P = 0.043), a longer external limiting membrane defect (P = 0.013), and a worse baseline BCVA (P = 0.017) than those with a smooth morphology. Postoperatively, in a multivariate regression model adjusting preoperative confounding effects, eyes with bumpy borders were associated with a longer ellipsoid zone defect (P = 0.006) and a thinner central fovea (P = 0.002) at 1 month, and a thinner central fovea (P = 0.005) and a worse BCVA (P = 0.015) at 10 months. Conclusion: A severe photoreceptor outer segment loss is common at the MH border, which represents a chronic pathogenic process and may be an independent predictor for an incomplete photoreceptor recovery and worse long-term visual outcomes after surgery.
