dc.description.abstract | Purpose: To evaluate the changes in choriocapillaris vessel density (VD) in eyes with pachychoroid pigment epitheliopathy (PPE) using swept-source optical coherence tomography (OCT) angiography (OCTA). Methods: This study included 83 eyes with PPE and 42 control eyes. We collected OCT and OCTA parameters, including central point thickness, subfoveal choroidal thickness (SFChT), and choriocapillaris VD of the fovea (CC fovea) and parafovea. The parafoveal area was divided into superior, nasal, inferior, and temporal choriocapillaris areas. Maximum (CC max) and minimum (CC min) choriocapillaris VD were defined as the highest and lowest values among the four parafoveal subfield VDs, respectively. We analyzed the average choriocapillaris VD, CC max, CC min, CC fovea, and the difference between CC max and CC min (CC delta) individually and compared all the parameters between PPE and control eyes. Results: CC max (56.0% ± 1.7%) was significantly higher and CC min (50.9% ± 2.0%) significantly lower in eyes with PPE than in control eyes (CC max, 55.3% ± 1.0%, P = 0.006; CC min, 51.5% ± 1.3%, P = 0.046). The CC delta value (5.0% ± 2.1%) and SFChT (389.9 ± 129.9 μm) were also significantly higher in eyes with PPE than in the control group (3.7% ± 1.5%, P < 0.001; 268.2 ± 102.2 μm, P < 0.001; respectively). Conclusions: Choriocapillaris VD showed higher variability (hyperperfusion and hypoperfusion) in eyes with PPE than in control eyes. Choriocapillaris hypoperfusion may precede the development of PPE; however, choriocapillaris hyperperfusion is associated with projection artifacts. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature. | - |
