ABSTRACT
BACKGROUND/OBJECTIVES:
This study aimed to investigate the change of choroidal venous overload in VogtâKoyanagiâHarada (VKH) disease. Clinical records of 52 patients with VKH disease (52 eyes) and 24 control subjects (24 eyes) who underwent multimodal imaging, including fluorescein angiography (FA) and indocyanine green angiography (ICGA), were retrospectively reviewed. SUBJECTS/METHODS:
Imaging data were assessed for signs associated with choroidal venous overload, e.g., choroidal perfusion delay, choroidal vascular hyperpermeability, dilated choroidal veins, and intervortex venous anastomosis (IVA). Dual FA and ICGA scoring for active posterior segment inflammation was performed. Clinical and imaging features associated with choroidal venous overload were compared between early- and late-stage VKH disease.RESULTS:
Choroidal perfusion delay, choroidal vascular hyperpermeability, dilated choroidal veins, and IVA were more prevalent in eyes with VKH disease (69.2%, 67.3%, 61.5%, and 65.4%, respectively) than in control eyes (25.0%, 20.8%, 25.0%, and 37.5%, respectively) (p < 0.05). All eyes with IVA in the early-stage of VKH disease had got other 3 signs. All choroidal venous overload signs were more prevalent in patients with early-stage (20 eyes) than in those with late-stage VKH disease (32 eyes) (p < 0.05). The number of choroidal venous overload signs were inversely related to disease duration (p < 0.001) and proportionally related to the total ICGA score (p < 0.001). IVA was significantly associated with the total ICGA score in logistic regression (p = 0.014).CONCLUSIONS:
Choroidal venous overload occurs early in VKH disease. Angiographic signs of choroidal venous overload may be useful markers to assess the status of VKH disease.
