    9. Comparative analysis of autofluorescence and OCT angiography in Stargardt disease

      Comparative analysis of autofluorescence and OCT angiography in Stargardt disease
      Aims To characterise the vasculature of the retina in patients with Stargardt disease (STGD) using optical coherence tomography angiography (OCTA) and to compare these functional findings with fundus autofluorescence (FAF) imaging. Methods This observational study included consecutive patients with STGD. The choriocapillaris (CC) layer was analysed on OCTA and retinal pigment epithelium (RPE) changes were assessed on FAF. Areas of CC and RPE impairment were quantified and correlated. Results Twenty-two ...

    15. Optical coherence tomography angiography in age-related macular degeneration: The game changer

      Optical coherence tomography angiography in age-related macular degeneration: The game changer
      Optical coherence tomography angiography is one of the biggest advances in ophthalmic imaging. It enables a depth-resolved assessment of the retinal and choroidal blood flow, far exceeding the levels of detail commonly obtained with dye angiographies. One of the first applications of optical coherence tomography angiography was in detecting the presence of choroidal neovascularization in age-related macular degeneration and establishing its position in relation to the retinal pigmented epithelium and ...
