PurposeTo evaluate the morphological changes before and after the formation of a full-thickness macular hole (MH) in highly myopic eyes.Patients and methodsRetrospective observational case series. From 2006 to 2013, clinical records of patients with MH and high myopia who had optical coherence tomography (OCT) before the development of MH were reviewed. All patients had been followed for more than 1 year since MH formation to observe the morphological changes.ResultsTwenty-six eyes of 24 patients were enrolled. The initial OCT images could be classified into four types: (1) normal foveal depression with abnormal vitreo-retinal relationship (eight cases), (2) macular schisis without detachment (six cases), (3) macular schisis with concomitant/subsequent detachment (nine cases), and (4) macular atrophy with underlying/adjacent scar (three cases). After MH formation, one case in type 1 and one case in type 4 group developed retinal detachment (RD). In type 2 group, four cases developed RD at the same time of MH formation. The preexisting detachment in type 3 group extended in eight cases and improved in one case. Among all the cases, 14 eyes received vitrectomy and 7 eyes received gas injection. MH sealed in nine eyes after vitrectomy and four eyes by gas injection.ConclusionThe study revealed four pathways of MH formation in highly myopic eyes. MH from macular schisis tended to be associated with detachment. However, the evolution and the results of surgical intervention were not always predictable.Eye advance online publication, 9 January 2015; doi:10.1038/eye.2014.312.
