摘要
AIM： To investigate the findings of infrared fundus autofluorescence（IR-AF） and spectral-domain optical coherence tomography（SD-OCT） in eyes with optic disc melanocytoma（ODM）.· METHODS： IR-AF findings and those of other ophthalmologic imaging examinations, including short-wave autofluorescence（SW-AF）, fluorescein angiography（FA）, fundus color photography, and SD-OCT of 8 eyes of 8 consecutive cases with ODM were assessed.·RESULTS： The ODMs in all cases（100%） presented similar IR-AF, SW-AF, and FA findings. On IR-AF images, ODMs showed outstanding hyper-AF with well-defined outline. On SW-AF images, the area of ODMs presented as hypo-AF. FA images revealed the leaking retinal telangiectasia on the surface of the ODMs. On SDOCT images in 8 cases（100%）, the ODMs were sloped with highly reflective surface, which were disorganized retina and optic nerve layers. In 7 cases（87.5%）, peripapillary choroids were involved. The melanocytomas of 8 cases（100%） presented as optically empty spaces. Vitreous seeds were found in one case（12.5%）.· CONCLUSION： IR-AF imaging may provide a new modality to evaluate the pathologic features of ODMs,and together with SW-AF imaging, offers a new tool to study biological characteristics associated with ODMs.SD-OCT is a valuable tool in delimitating the tumor extension and providing morphological information about the adjacent retinal tissue.
