Follow-up of retinoblastoma using RetCam fluorescein angiography and correlation with clinical findings.

RetCam wide-angle FA is useful to evaluate the tumor and associated vascular and retinal changes after treatment in RB. Regressed tumors demonstrate later fluorescein uptake in venous phases. Fluorescein angiographic changes in chorioretinal scars include window defects, visibility of choroidal vessels, scleral staining, and leakage from vessels. Retinal vascular leakage and peripheral non-perfusion can be seen in eyes with regressed stable tumors.
