ABSTRACT

Introduction: Serous separation of the neurosensory retina is a hallmark of central serous chorioretinopathy. It is mainly caused by choroidal vascular dysfunction, which consequently leads to retinal pigment epithelium damage. While spontaneous resolution may be possible, relapses occur frequently, especially following focal laser photocoagulation. This is due to the fact that the basic choroidal pathology in the course of CSC is not effectively treated. Case presentation: A 47-year-old patient presented to the outpatient department with blurred vision and dyschromatopsia in his right eye. Due to the unavailability of photodynamic therapy at the facility, focal laser photocoagulation was performed, achieving clinical improvement. Six months after the treatment, the patient was admitted again with a relapse. Discussion: The observed recurrence points to the validity of the use of photodynamic therapy that affects the excessive permeability of choroidal vessels. Unfortunately, access to this treatment method remains limited in many countries, which affects the long-term outcomes. Conclusions: The case underlines the importance of selecting a treatment modality that targets the root pathophysiology of central serous chorioretinopathy. It also stresses the need to increase access to photodynamic therapy to improve patient care.
