Imaging biomarkers of leukaemic choroidopathy.

The study demonstrates a subclinical choroidal involvement in patients with AL, with relative stromal thickening in the acute phase, and normalization after disease remission. Choroidal HRF were identified as a biomarker of leukaemic choroidopathy. Choriocapillaris and choroidal vascularity were inversely correlated with a systemic pro-coagulant state.
