Polypoidal choroidal neovasculopathy (PCV) is a subtype of wet age related macula degeneration (AMD) occuring more commonly in the Asian population. Besides the phenotypic differences, PCV is thought to have a lesser response to anti VEGF therapy which is the mainstay of treatment for other typical wet AMD. Recent trial data suggest that a combination with photodynamic therapy may help in the visual and anatomical outcome of PCV, and emerging evidence shows favourable outcomes the newer anti VEGF agent, aflibercept 2mg monotherapy. These trials however, have assessed aflibercept in a strict 2mg every 8 weekly regime. In the clinical setting, a significant an unmet need in the management of PCV is a tailored treatment regime. Here we propose a treatment regimen based on disease activity for PCV with aflibercept mono therapy. A limitation of the 2q8 regime is that it is fixed and does not vary regardless of polyp closure or anatomical outcome at the first time point of assessment (month 3). We hypothesize that after the initial 3 monthly injections of aflibercept, about 50% of PCV will close and become quiescent, and in the remaining 50%, a further 3 monthly injections will increase overall polyp closure rate. After a loadings phase of either 3 or 6 months, all eyes will start on a treat and extend regime (T\&E), with a minimum period of 8 weeks and a maximum of 12 weeks between treatments with 2 week increments if PCV remains quiescent. The proposed study aims to evaluate the efficacy of a modified treat and extend regime based on disease activity with aflibercept monotherapy for PCV.
