Outer retinal folds in highly myopic macular hole and retinal detachment.
OBJECTIVE
To report the intraretinal microstructure in macular hole and retinal detachment in a highly myopic eye using spectral-domain optical coherence tomography.


METHODS
Two eyes of two patients with macular holes and retinal detachment were examined with spectral-domain optical coherence tomography. Fundus photographs and time-domain optical coherence tomography images also were obtained.


RESULTS
Spectral-domain optical coherence tomography disclosed outer retinal fold formation toward the subretinal space at the level of the photoreceptor inner and outer segment layer, the cystoid spaces expanding outside of the macular hole and epiretinal membrane in all eyes.


CONCLUSIONS
The outer retinal fold may indicate the tension of the inner retina and the redundancy of the outer retina, which may be responsible for the occurrence of macular holes and retinal detachment in these eyes.
