Abstract
Background Due to intraoperative optical coherence tomography (iOCT), observation of retinal morphological changes during surgery has become possible. Objective To analyze the intraoperative morphology of full thickness macular holes (FTMH) and the correlation with the postoperative function, a retrospective, observational clinical study was performed analyzing 32 eyes of patients treated at the hospital of the technical university of Munich. Material and methods Using iOCT in 32 eyes of 32 consecutive patients, the operative morphology was analyzed during surgery. These findings were then correlated with the postoperative visual outcome. Results After posterior vitreous detachment (PVD) the macular hole index (MHI) decreased by -0.05 (p = 0.01) and the base diameter (BD) increased by +99.4 mu m (SD = 197.8 mu m;p = 0.04). Closure rate was 100% at the first visit after a mean time of 73 days and the postoperative best corrected visual acuity (BCVA) significantly improved (p < 0.05). There were significant correlations between intraoperative morphology and postoperative results indicating a relation between low MHI and better postoperative BCVA (SCC = 0.50;p = 0.02), large BD and better postoperative BCVA (SCC = 0.43;p = 0.05) and large aperture after PVD and higher improvement of BCVA (SCC = 0.44;p = 0.03). Conclusion Flattening and broadening of the FTMH occurred as a result of reduction of vitreoretinal traction. The significant correlation between a large operative BD and improved BCVA reveals the importance of intraoperative retinal relaxation.
