Spectral domain optical coherence tomography (SD-OCT) scans of the amblyopic (top left) and non-amblyopic (top right) eyes of a child with persistent amblyopia.(Subramanian et al., in press) Overall (n=26), there were no significant differences in total macular thickness or in any of the ETDRS macular sectors (second panel) between amblyopic and fellow eyes (p>0.2 for all paired t-tests.) The third panel shows a sample SD-OCT scan of the RNFL obtained by SD-OCT and means for each RNFL sector; there were no significant differences in global RFNL thickness nor in any sector between amblyopic and fellow eyes (p>0.4 for all paired t-tests). The bottom panel illustrates the method used to quantify optic disc dysversion (Horiz:Vert disc diameter ratio). No significant differences were found for amblyopic vs. fellow eyes (H/Vambly= 1.15 ±0.18; H/Vfellow= 1.14±0.17; p=0.87). Hypoplasia (assessed by area of the optic disc, mm2) did not differ for amblyopic vs. fellow eyes (Areaambly= 1.88±0.44; Areafellow= 2.10±0.61; p=0.26).
