Fig. 3From: Evaluating photodynamic therapy versus brolucizumab as a second-line treatment for polypoidal choroidal vasculopathyA polypoidal choroidal vasculopathy case managed with secondary PDT without additional treatment. A Pre-treatment Optical coherence tomography (OCT) reveals pigment epithelial detachment (PED) with sharp peaks and sub-retinal pigment epithelium ring-like lesions. B Corresponding indocyanine green angiography (ICGA) captures multiple polyps. C 12-month post-PDT OCT shows diminished PED and resolved retinal fluid with no further treatment. D A similar OCT of the subfoveal area indicates remission of retinal fluid.
