Current and emerging treatment options for central serous chorioretinopathy

Abstract

ABSTRACT Introduction Central Serous Chorioretinopathy (CSC), a leading cause of vision loss, presents diverse treatment challenges based on its acute or chronic manifestation. Areas covered In acute CSC, treatment typically involves observation, reserving intervention for cases where optimal vision is crucial for professional activities. Emerging evidence advocates the use of half-dose or half-fluence Photodynamic Therapy (PDT), directed by Indocyanine Green Angiography (ICGA) or Fluorescein Angiography (FA), to hasten subretinal fluid (SRF) resolution, improve vision, and minimize recurrence. Chronic CSC, on the other hand, increasingly favors half-dose PDT, a recommendation strengthened by studies such as the PLACE trial. CSC complicated by Choroidal Neovascularization (CNV) necessitates management through intravitreal anti-Vascular Endothelial Growth Factor (anti-VEGF) injections and/or half-dose PDT. In cases of polypoidal choroidal vasculopathy (PCV), a combination of anti-VEGF therapy with PDT proves beneficial. For scenarios where standard treatments are impractical, Eplerenone emerges as the primary oral medication. Methods A literature search of all original articles was performed using the major online databases. The following keywords ‘Central Serous Chorioretinopathy’ and ‘Treatment,’ were searched in combination with ‘Photodynamic therapy,’ ‘Focal Laser Photocoagulation,’ ‘Subthreshold Micropulse Laser’ and ‘Systemic treatments.’ Expert opinion Managing CSC requires a patient-centered approach. In acute CSC, careful monitoring and lifestyle modifications may suffice, while in chronic CSC, PDT is a primary therapeutic option.
