AIM
To demonstrate the usefulness of a recently
developed technique of imaging fundus autofluorescence and to compare
it with the results of fluorescein angiography in the diagnosis and
staging of macular holes.
METHODS
The intensity and distribution of fundus
autofluorescence was studied in 51 patients with idiopathic macular
holes and pseudoholes using a confocal laser scanning ophthalmoscope
(cLSO) and the images were compared with those obtained by fundus
fluorescein angiography.
RESULTS
Autofluorescence imaging demonstrated
bright fluorescence of macular holes with appearance similar to that
obtained by fluorescein angiography. In contrast macular pseuodoholes
showed no such autofluorescence. The attached operculum in stage 2 macular holes and the preretinal operculum in stage 3 macular holes
showed focal decreased autofluorescence. The associated retinal
elevation and the cuff of subretinal fluid were less fluorescent
compared with the background autofluorescence of the normal fellow
eyes. Following successful surgical treatment the autofluorescence of
the macular holes was no longer visible.
CONCLUSION
Autofluorescence imaging with the cLSO
makes the assessment of macular holes possible with an accuracy
comparable with that of fluorescein angiography. Being non-invasive
and rapid, autofluorescence imaging may become a useful alternative to
fluorescein angiography in the assessment and the differential
diagnosis of full thickness macular holes.
