Purpose |
To determine whether a recovery of the microstructures of the foveal photoreceptors after macular hole closure is correlated with best-corrected visual acuity (BCVA).
Design |
Retrospective, consecutive, observational case series.
Methods |
setting: Single-center academic practice. study population: Forty-one eyes of 41 patients with surgically closed macular holes. observational procedures: The presence and intactness of the cone outer segment tips (COST) line were determined by spectral-domain optical coherence tomography and compared with the presence of the inner segment/outer segment (IS/OS) junction and the external limiting membrane (ELM) at 1, 3, 6, 9, and 12 months after the macular hole surgery. main outcome measure: The correlation between the integrity of the foveal photoreceptor microstructures and the BCVA.
Results |
A distinct COST line was first seen at 6 months after the surgery. A distinct or irregular COST line was observed only in eyes with an intact IS/OS junction and ELM. Eyes with a distinct or irregular COST line had significantly better BCVA than those with a disrupted COST line in eyes with an intact IS/OS junction and ELM at 12 months (P = .030). The BCVA was ≥20/25 at 12 months in 91% of the eyes with a distinct or irregular COST line but in only 44% of the eyes without a COST line (P = .015).
Conclusions |
The significant correlation between the BCVA and a distinct or irregular COST line after successful macular hole surgery indicates that the recovery of foveal cone microstructure is associated with good postoperative BCVA.
