Macular hole: improved understanding of pathogenesis, staging, and management based on optical coherence tomography.

Optical coherence tomography (OCT) has improved the understanding and management of idiopathic macular hole. Images of precursor lesions and their progression demonstrate that antero-posterior as well as tangential traction are involved in macular hole formation. The staging of macular holes with biomicroscopic examination can be paralleled by optical coherence tomography staging with some modification. OCT is useful in differentiating simulating lesions and in allowing better counseling of patients regarding their disorder. Finally, OCT findings are prognostic of surgical success and can assist in evaluating the results of surgery.
