Purpose: To assess the longitudinal surgical outcomes of macular telangiectasia Type 2 macular hole (MacTel-MH) and compare them with those of idiopathic MH. Methods: This retrospective, single-tertiary center study included patients who underwent MH surgery between January 2015 and September 2023. Patients with characteristic optical coherence tomography findings of MacTel in both eyes or those who underwent fluorescence angiography were classified as having MacTel MH. Baseline and postoperative best-corrected visual acuity and optical coherence tomography parameters were reviewed. Results: Totally, 27 and 243 eyes with MacTel and idiopathic MH, respectively, were included. Macular hole closure rate was better achieved in idiopathic than in MacTel MH group at two years postoperatively. Temporal recovery of ellipsoid zone and external limiting membrane was more prominent in MacTel than in idiopathic MH group. Statistically significant visual acuity improvement was seen between three months and two years postoperatively in MacTel MH group. Conclusion: To the best of our knowledge, this is the first study to analyze the surgical outcomes of MacTel MH in both anatomical and functional aspects and compare them with patients with idiopathic MH. Postoperative microglia change would have affected the restoration of outer retinal layer of patients; however, further studies are needed for clarification.
