Baseline characteristics associated with greater risk of scarring were predominantly classic choroidal neovascularization ( CNV ) ( aHR , @ ; CI , @-@ @ ) versus occult CNV , blocked fluorescence ( aHR , @ ; CI , @-@ @ ) , foveal retinal thickness > @ m ( aHR , @ ; CI , @-@ @ ) versus < @ m , foveal subretinal tissue complex thickness > @ m ( aHR , @ ; CI , @-@ @ ) versus @ m , foveal subretinal fluid ( aHR , @ ; CI , @-@ @ ) versus no subretinal fluid , and subretinal hyperreflective material ( SHRM ) ( aHR , @ ; CI , @-@ @ ) versus no SHRM .
