Risk Factors and Outcomes of Postoperative Macular Hole Formation after Vitrectomy for Myopic Traction Maculopathy: SCHISIS Report No. 2.
Ophthalmology Retina 2023 September
PURPOSE: To evaluate the incidence, pathogenesis, risk factors, and treatment outcomes of postoperative macular hole (MH) after pars plana vitrectomy (PPV) for myopic traction maculopathy (MTM).
DESIGN: Multicenter, interventional, retrospective case series.
SUBJECTS: Consecutive eyes that underwent PPV for MTM with a minimum 6-month follow-up.
METHODS: We investigated the characteristics and treatment outcomes of postoperative MH after MTM surgery.
MAIN OUTCOME MEASURES: Incidence, risk factors, and anatomic and visual outcomes of postoperative MH.
RESULTS: We included 207 eyes (207 patients) with a mean follow-up of 25.9 months. During follow-up, 24 (11.6%) eyes developed MH (10 with concurrent MH retinal detachment); 15 eyes within 30 days (early), 4 eyes between 31 and 180 days (intermediate), and 5 eyes after 180 days (late). Logistic regression analysis revealed male gender (odds ratio [OR], 2.917; 95% confidence interval [CI], 1.198-7.100; P = 0.018), thinner preoperative choroidal thickness (OR, 0.988; 95% CI, 0.976-1.000; P = 0.048), and use of indocyanine green for internal limiting membrane peeling (OR, 2.960; 95% CI, 1.172-7.476; P = 0.022) as significant risk factors for postoperative MH. Internal limiting membrane peeling with a fovea-sparing technique tended to protect against postoperative MH, but it was not statistically significant (P = 0.096), because 1 eye still developed MH. Postoperative MHs were treated by observation (6 eyes), in-office octafluoropropane (C3 F8 ) gas injection (7 eyes), or PPV (11 eyes). Macular hole closure was achieved in 20 eyes (83%). The hole closure rate was 67% (4/6 eyes) after observation, 71% (5/7 eyes) after C3 F8 gas injection, and 91% (10/11 eyes) after PPV. However, visual outcomes were significantly worse for eyes with postoperative MH than those without (0.38 ± 0.43 vs. 0.68 ± 0.46; P = 0.002).
CONCLUSIONS: Postoperative MH may occur in 11.6% of patients with MTM at any time after surgery. Retreatment resulted in relatively favorable anatomic closure but unfavorable visual outcomes.
