Abstract Purpose To assess the incidence of normal vision following anatomically successful macular hole surgery and associated clinical variables. Methods Multicentre, retrospective chart review. Preoperative, intraoperative and postoperative clinical data were extracted from electronic medical records from seven European vitreoretinal units. Inclusion criteria were as follows: eyes undergoing primary vitrectomy for idiopathic full‐thickness macular hole from January 2015 to January 2018; postoperative macular hole closure confirmed by spectral domain optical coherence tomography (OCT); preoperative pseudophakia or phakic eyes receiving combined cataract surgery; one‐year follow‐up. The primary outcome was ‘normal vision’ defined as a final best‐corrected visual acuity (BCVA) ≥ 20/25. Univariate, multivariate and decision‐tree analyses were conducted to evaluate the clinical variables associated with ‘normal vision’. Odds ratios (OR) and confidence intervals (CIs) were calculated. Results Of 327 eligible cases, 91 (27.8%) achieved ‘normal vision’ at 1 year. Multivariate analysis identified variables significantly associated with ‘normal vision’: shorter symptom duration (odds ratio [OR]=1.05; 95% confidence interval [CI]:1.02‐1.09; p = 0.002), smaller preoperative OCT minimum linear diameter (OR per 100‐micron increase = 1.65; 95%CI:1.31‐2.08; p < 0.001) and better mean preoperative BCVA (OR = 15.13; 95%CI: 3.59‐63.65; p < 0.001). The decision‐tree analysis found that the most significant variable associated with ‘normal vision’ was symptom duration. ‘Normal vision’ was achieved in 70.6% of eyes operated within one week from symptom onset and in 45% of eyes with symptom duration between 1 and 3 weeks. Conclusions These findings suggested urgent surgery is justified for small macular holes of short duration.
