Abstract

Macular hole (MH) is a common cause of blurry vision in elderly. This cross sectional descriptive study had aimed to find out the clinical outcome of macular hole surgery in Buddhachinaraj Phitsanulok hospital. Thirty-two patients (32 eyes) who had been diagnosed with full thickness MH by optical coherence tomography (OCT) and underwent vitrectomy with at least 3-month follow-up period were included. The patients had mean age 64.67 ± 5.34 years. Pre-operative mean best corrected visual acuity (BCVA) was1.20 ± 0.33 LogMAR (20/320). OCT showed mean base diameter of MH 1021.12 ± 292.20 μm and mean MH height 452.75 ± 87.11 μm. 28.1% of the patients were medium size MH and 71.9% were large size. The anatomical closure rate was 71.9% and mean final BCVA was0.96 ± 0.40 LogMAR (20/160). Closed hole group had better BCVA change (-0.30 ± 0.31 vs 0.06 ± 0.19 LogMAR, p = 0.014) and better final BCVA (0.84 ± 0.37 vs 1.27 ± 0.32 LogMAR, p = 0.013) (20/125 vs 10/200). 50.0% of patients had better BCVA and 43.8% had stable BCVA. Combined cataract surgery and short hole height are related with unclosed hole (p = 0.018 and 0.015). In conclusion, the result of macular hole surgery in Buddhachinaraj Phitsanulok hospital is comparable to international standard. Factors associated with the closure of MH in this study were the height of MH and combined cataract surgery.
