AIM: We investigated fundus autofluorescence (FA) patterns and tomographic retinal changes by means of optical coherence tomography (OCT 3) in adult-onset foveomacular vitelliform dystrophy (AOFVD) and their possible correlation with best-corrected visual acuity (BCVA). METHODS: Eighteen eyes of 15 consecutive patients (mean age: 73.73 +/- 9.5 years) presented to our observation with a diagnosis of AOFVD underwent BCVA measurement, evaluation of FA distribution by means of a confocal laser scanning ophthalmoscope and OCT 3 tomography. RESULTS: The mean BCVA was 20/40 (range: 20/20-20/100). The FA pattern was patchy in 9 eyes (50%), ring-like in 5 (27.7%), focal in 3 (16.6%) and linear in 1 (5.5%). No correlation between FA patterns and BCVA was found. OCT 3 showed accumulation of highly reflective material between the neurosensory retina and retinal pigment epithelium (RPE) in 12 eyes (66.6%) with an evident overlying photoreceptor layer (PRL). In 5 eyes the highly reflective material was built up between the neurosensory retina and RPE without evidence of PRL (27.7%). Only in 1 eye was the subretinal accumulation site not well defined (5.5%). The mean thickness of the deposit was 135.52 +/- 47.53 microm, while the residual neurosensory retina thickness was 103.94 +/- 24.21 microm. The relationship between BCVA and the thickness of the neurosensory retina over the lesion was not significant (p = 0.016, r = 0.33), while the correlation between BCVA and the material deposit thickness (p = 0.017, r = 0.12) was significant. CONCLUSIONS: In AOFVD, FA presented different patterns, while OCT usually shows a well-defined material accumulation with a generally reduced neurosensory thickness between PRL and RPE. FA imaging and OCT are useful and safe for the diagnosis and follow-up of AOFVD. (c) 2008 S. Karger AG, Basel.
