    Characterization of Stargardt disease using polarisation-sensitive optical coherence tomography and fundus autofluorescence imaging

    Purpose: To identify disease-specific changes in Stargardt disease (STGD) based on imaging with polarisation-sensitive spectral-domain optical coherence tomography (PS-OCT) and to compare structural changes to those visible on blue light fundus autofluorescence (FAF)imaging. Methods: 28 eyes of 14 patients diagnosed with STGD were imaged using a novel high-speed, large-field PS-OCT system and FAF (Heidelberg Retina Angiograph/Spectralis, Heidelberg Engineering, Germany; excitation 488nm, emission >500nm). The ophthalmoscopic phenotype was classified into 3 groups as suggested by Fishman et al. ABCA4 mutation testing detected 15 STGD alleles, 6 of which harbour novel mutations. Results: STGD phenotype 1 (12 eyes) showed sharply ...
