    Abstract

    Background/aims: To evaluate the visual performance of patients with successful macular hole surgery with a minimum follow up of 3 years. Results were compared with the performance of the healthy fellow eyes.

    Methods: 15 patients were studied. The healthy fellow eyes of the patients (13 eyes) served as control-group. Age, gender and best-corrected LogMAR visual acuity were recorded. Reading acuity (in LogRAD) and speed were tested monocularly. Scotoma size was measured with SLO- perimetry and hole closure was confirmed with an OCT-scan.

    Results: Mean distance visual acuity of the operated eyes (LogMAR 0.32±0.21) was significantly lower than of the healthy fellow eyes (LogMAR 0.05±0.17), but significantly higher than preoperatively (LogMAR 0.71±0.32). Mean reading acuity was LogRAD 0.47±0.25 for the operated eyes (=77.9% of LogMAR), and statistically significantly higher (LogRAD 0.16±0.16) for the fellow eyes (=89.4% of LogMAR). Mean maximum reading speeds were comparable for the operated eyes (168.3 ±23.1 wpm) and the fellow eyes (178.7 ±26.1wpm), (p=0.3). Within LogRAD 1.3 and 0.5, mean reading speeds of the two groups were comparable, but critical print size (CPS) for the operated group (LogRAD 0.7±0.2) was significantly worse than those for the fellow eyes (LogRAD 0.4±0.2). The SLO analysis showed absence of absolute scotoma in 12 eyes.

    Conclusion: Distance and reading acuity showed remaining deficits compared to the healthy fellow eyes, however, mean maximum reading speeds of the operated eyes had achieved results comparable to healthy eyes. The results show a long term benefit in visual function of eyes with closed macular holes.
