Table 1 Pathological features detected on different layers of OCTA in various uveitis entities
Superficial capillary plexus | Deep capillary plexus | Outer retina | Choriocapillaris | Choroid | |
|---|---|---|---|---|---|
Retinal vasculitis | -Decreased flow density -Enlargement/ Irregularity of FAZ -Capillary remodeling | -Grayish hypo/non perfused areas -Elevated, dilated or shunting perifoveal vessels -Well delineated flow void areas | |||
Birdshot retinochoroiditis | -Telangiectatic vessels -Increased intercapillary space in the perifoveal region | ||||
Ocular toxoplasmosis | Neovascular network arising from retinal vasculature with no contribution of the choroid | ||||
MEWDS | Normal flow | ||||
APMPPE | Flow reduction and ischemia | Flow reduction and ischemia | |||
PIC/MCP | Tangled vessels arising from choriocapillaris | -Focal flow reduction (MCP) -Tangled vessels extending into outer retina | |||
Serpiginous choroiditis | Flow reduction in areas of active lesions | Better delineated vessels in areas of inactive lesions | |||
Sarcoidosis | Flow void areas | ||||
Tuberculosis | -Flow void areas -Tangled vessels arising from choriocapillaris | ||||
VKH | Focal flow void | ||||
Uveitic macular edema | Decreased capillary density | ||||
Inflammatory CNV | Neovascular network |
