Pachychoroid Spectrum Disease and Central Serous Chorioretinopathy Treatment with Subthreshold Micropulse Laser and Verteporfin Photodynamic Therapy

Abstract

The common morphological features of pachychoroid spectrum disease are defined by an increase in choroidal thickness due to dilated choroidal vessels in Haller’s layer. A wide range of clinical alterations has been defined within the pachychoroid disease spectrum including, pachychoroid pigment epitheliopathy, central serous chorioretinopathy, pachychoroid neovasculopathy, polypoidal choroidal vasculopathy, focal choroidal excavation, peripapillary pachychoroid syndrome. In patients experiencing vision loss due to central subretinal fluid, pigment epithelial detachment, and choroidal neovascularization, treatment should be considered to improve or stabilize visual function. Nowadays, Anti-Vascular endothelial growth factor (VEGF) therapy, subthreshold micropulse laser, and verteporfin photodynamic therapy are commonly used treatment modalities.
