Abstract

Aims: Study the choroidal neovascularization (CNV) morphological evolution after treatment using optical coherence tomography angiography (OCTA). Method: We used Optovue XR Avanti, with split-spectrum amplitude-decorrelation angiography algorithm. Results: OCT Angiography allows to recognize better the CNV type. In our series all our cases seem to follow a 45 to 60 days cycle, after intra vitreal injection. After each injection a pruning of smaller vessels is seen immediately (after 24 hours) that increases for 6 to 12 days when it reaches a maximum. It is followed by a reopening or new sprouting of the vessels 20 to 50 days later. The later cycles seem longer. Our results on early CNV evolution seem to confirm previous observations of CNV abnormalization and arterialization. Pruning the small peripheral branches seems to strengthen the trunk. In OCTA, closing terminal vessels (anti-VEGF effects) seems to cause an increased flow in trunk after the CNV reactivation.
