Choroidal filling delay in choroidal neovascularisation due to pathological myopia

AIM To assess the choroidal thickness and choroidal circulatory changes in eyes with myopic choroidal neovascularisation (mCNV). METHODS Retrospective, consecutive, observational case series. Forty-two consecutive eyes (17 eyes with newly diagnosed mCNV and 25 eyes without CNV) were included. Choroidal circulation was evaluated by indocyanine green angiography (ICGA), and choroidal thickness was measured by spectral-domain optical coherence tomography (SD-OCT). The factors associated with mCNV were evaluated. RESULTS Sixteen (94%) of 17 eyes with mCNV and six (24%) of 25 eyes without mCNV had well-defined hypofluorescence at the macular region on arterial phase ICGA, that is, a choroidal filling delay.
