Choriocapillaris flow impairment surrounding geographic atrophy correlates with disease progression
Fig 5
Examples of eyes with geographic atrophy and different growth rate.
One eye from two patients with geographic atrophy (GA) are shown in the two rows of images. A and D are the optical coherence tomography (OCT) fundus photos at baseline while B and E were acquired after one year. The two patients show a very different yearly growth rate (0.07 and 0.73 for the first and second row respectively). The OCT angiogram at the level of the choriocapillaris (C and F) from the baseline visit for these two patients shows dramatically different flow impairment surrounding the lesion, with considerably greater flow voids in the latter case (41,2% versus 53% for the first and second row respectively).
