Comparison of Morphological Features of Type 1 CNV in AMD and Pachychoroid Neovasculopathy: An OCTA Study

BACKGROUND AND OBJECTİVE: The purpose of this study is to compare the morphological features of type 1 choroidal neovascularization (CNV) in eyes with age-related macular degeneration (AMD) and pachychoroid neovasculopathy (PNV) using optical coherence tomography angiography (OCTA). PATİENTS AND METHODS: Nineteen eyes of 17 patients with PNV and 30 eyes of 30 patients with AMD were evaluated. The size and area of CNV and morphological patterns during a 6-month period were analyzed using optical coherence tomography angiography. RESULTS: The presence of a feeder vessel was more common in AMD than in PNV. Indistinct pattern was more common in PNV than ...
