Spectral-domain optical coherence tomography findings after indocyanine green-assisted vitrectomy for idiopathic macular hole.
OBJECTIVE
To report the intraretinal changes seen on the spectral-domain optical coherence tomography after indocyanine green (ICG) assisted internal limiting membrane peeling for macular hole.


METHODS
A 76-year-old woman with closed macular hole after ICG-assisted internal limiting membrane peeling presented poor visual acuity. Infrared-red, fundus autofluorescence, ICG fluorescence, time-domain OCT and spectral-domain optical coherence tomography images were obtained.


RESULTS
Spectral-domain optical coherence tomography showed the irregular bumps of the retinal pigment epithelium, thinning of the overlying photoreceptor inner and outer segment layer, and enhanced reflectivity of external limiting membrane layer that corresponded to residual ICG fluorescence dots. The area of retinal pigment epithelium changes and inner and outer segment layer disruption seemed to correspond to residual ICG fluorescence in the previous macular hole bed.


CONCLUSIONS
The intraretinal changes were observed in areas of retained ICG after ICG-assisted internal limiting membrane peeling. Spectral-domain optical coherence tomography detected these changes clearly.
