About

In our experience, elongation of foveal tissue after macular hole surgery which was undetectable by conventional time-domain optical coherence tomography was often observed on spectral-domain optical coherence tomography images. Elongation of tissues inevitably induces some degree of disorganization of tissue microstructure.

The purpose of the present study was to evaluate elongation profile of foveal tissue after macular hole surgery and to investigate its impact on visual acuity and metamorphopsia.

Inclusion criteria

Patients who were diagnosed with idiopathic macular hole

Exclusion criteria

traumatic macular hole
evidence of ocular inflammation, diabetic retinopathy, hypertensive retinopathy, and retinal vasculitis, media opacity that would influence visual acuity or preclude acquisition of clear spectral domain optical coherence tomography images
presence of cataract judged to affect visual function, -6.0 diopters or more of spherical equivalent, prominent staphyloma
history of intraocular surgery other than uncomplicated cataract surgery, other ocular diseases that may influence the macular microstructure or visual function
patients with indistinct intraretinal structure on spectral domain optical coherence tomography images
