Objective:
To determine the correlation between clinical and optical coherence tomography findings in macular hole closure status after surgery.
Materials And Methods:
Consecutive patients who underwent macular hole surgery were recruited prospectively. All patients underwent detailed macular examination with noncontact and contact biomicroscopy, and linear cross-sectional optical coherence tomography was performed. Macular hole status was defined as elevated/open, flat/open, and flat/closed. Pearson's correlation coefficient was calculated to study the relationship between the clinical and optical coherence tomography findings by assigning a pseudo-value for hole status.
Results:
Twenty-eight patients were recruited, with optical coherence tomography performed successfully in 27 cases. There was good correlation between the optical coherence tomography findings with both the noncontact (r = 0.965; P < .001) and contact lens biomicroscopy (r = 0.965; P < .001).
Conclusion:
Optical coherence tomography findings of postoperative macular hole closure status correlate well with the clinical findings. Careful clinical examination alone may be adequate in determining the surgical anatomical end points in the majority of patients after macular hole surgery.
