Abstract

Purpose : Several variants in genes involved in the complement system have been described to be associated with chronic central serous chorioretinopathy (cCSC). Previously, systemic activation of the complement system in age-related macular degeneration, a disease that shows clinical features that overlap with CSC, has been found. With this case-control study, we assessed whether there is a systemic activation of the complement system in patients with cCSC.

Methods : A prospective cohort study of 77 typical cCSC patients and 31 age- and gender-matched controls without ophthalmological history. Either in serum or plasma, hemolytic complement assays (AP50, CP50, and LP50), complement components C3, C4, CFB, CFH, and CFI and C3d, C5a and C5b-C9 (activation products), and the C3d/C3 ratio were analysed. A correction for possible effects of gender, age, body mass index, and smoking status was performed.

Results : Before performing the Bonferroni correction for multiple testing, activation of the classical complement pathway (p=0.049) and C5a (p=0.012) were associated with cCSC. However, after performing this correction, none of the tested variables proved to be statistically significantly different between the included groups.

Conclusions : Despite the available literature regarding a possible relationship between cCSC and variants in genes involved in the complement system, the current study did not find evidence that cCSC is associated with systemic complement activation.
