A lower rate of development of chorioretinal atrophy, smaller pretreatment CNV size, and younger age were indentified as the most consistently significant prognostic factors affecting the efficacy of IVB in eyes of myopic CNV and were associated with improved BCVA. A worse BCVA after IVB in eyes with myopic CNV probably was associated with subfoveal CNV, lower baseline BCVA, longer duration of CNV, incomplete regression of CNV, subretinal hemorrhage, and previous PDT treatment. No apparent association were observed between the refraction error, axial length, lens status and change in BCVA after IVB. We indentified significant prognostic factors in this systematic review study that might allow for the selection of patients with myopic CNV which are most likely to benefit from IVB.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
