Advances in retinal imaging modalities: Challenges and opportunities

Figure 1 Retinal photographs by various funds cameras. A: Colour fundus photo showing left eye with proliferative diabetic retinopathy; (Image taken by Zeiss Cirrus photo 800). Compare with Figure 1B; B: Red-free fundus photo (left eye with proliferative diabetic retinopathy). Better visualisation of new vessels and retinal haemorrhages as opposed to Figure 1A; C: Colour fundus photo (left) vs fundus autofluorescence (right); Retinal exudates are more visible on the colour fundus photo. Autofluorescence highlights the laser scars not readily visible on a colour fundus photo; D: Seven-field fundus photo - computer-aided mosaic (Image taken by Zeiss Cirrus 800); E: Seven-field fundus with fluorescein angiography (Image taken by Zeiss Visucam D500).
