Central Serous Chorioretinopathy (CSC)

Dysregulation of the Angiopoietin-2 (Ang-2)/Tyrosine kinase with Immunoglobulin-like and EGF-like domains 2 (Tie-2) signaling pathway has been implicated in choroidal vascular instability and RPE dysfunction in Central serous chorioretinopathy (CSCR) and pachychoroid-associated neovascularization. This study prospectively evaluates the efficacy and safety of faricimab compared to sham in CSCR with and without secondary neovascularization, using standardized anatomical and functional endpoints. The results of this trial may help define the role of dual pathway inhibition in CSCR and inform future treatment strategies for this challenging and vision threatening condition.

By leveraging parameters including fractal dimension and topological index, we constructed a quantitative evaluation framework for ultra-widefield optical coherence tomography angiography (UWF-OCTA) images in patients with central serous chorioretinopathy (CSC), thus overcoming the limitations of conventional qualitative analysis.
