Vitreous surgery for macular hole

Detailed Description:

Spectral domain optical coherence tomography (SD-OCT) was used to calculate the mean length of photoreceptor cone outer segment tips (COST) defect on 1, 3, 6, 9, and 12 months after macular hole surgery. The correlation between the mean length of COST defect and the BCVA was determined. Prognostic factors might have influenced for COST repair was also evaluated by multivariable analysis.
