Choroidal thickness changes and choriocapillary circulation analysis in macular holes using optical coherence tomography angiography.

Background: To investigate the changes of subfoveal choroidal thickness (SFCT) and choriocapillary circulation in idiopathic macular holes (IMHs), the fellow eyes, and normal subjects using optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA), and to explore the role of SFCT and choriocapillary circulation in the pathogenesis of IMH.

Methods: A case series of 30 patients with unilateral IMH and 30 subjects, with age- and sex-matched, were included. Thirty eyes of 30 patients with unilateral IMH, the unaffected fellow eyes, and 30 eyes of age- and sex-matched healthy patients were studied.
