Choroidal hypoperfusion associated with photodynamic therapy for choroidal neovascularization / 中华实验眼科杂志

ABSTRACT

Choroidal neovascularization (CNV) ithe leading cause of vision disordecaused by variouretinal diseases.Apresent,many therapeutimethodare employed clinically,such aphotodynamitherapy (PDT),anti-vasculaendothelial growth facto(anti-VEGF) and transpupillary thermotherapy (TTT).However,none of them can cure CNV thoroughly and repeated treatmenirequired usually.The reason forecurrenCNV istill unclear.Choroidal hypoperfusion associated with Pdmay be one of the reasons.The purpose of thireview ito discusthe problem of choroidal hypoperfusion associated with PDfoCNV awell aitimpacon the eye and possible solutions.Thipapepresentevidenceof choroidal hypoperfusion aftePDand itrelationship with clinical outcomes.Meanwhile,the effecof combination therapy iassessed.Finally,low-fluence Pdirecommended apotential method to reduce choroidal hypoperfusion.
