Purpose: To increase insight into the myopic presentation of central serous chorioretinopathy (CSC) by comparing a large group of myopic patients with CSC with reference groups with only one of the diagnoses. Methods: Myopic patients with CSC (spherical equivalent #23D, n = 46), emmetropic patients with CSC (spherical equivalent 20.5 to 0.5 D, n = 83), and myopic, non-CSC patients (n = 50) were included in this multicenter cross-sectional study. Disease characteristics and imaging parameters, such as subfoveal choroidal thickness and indocyanine green angiography patterns, were compared between cases and reference groups. Results: In myopic patients with CSC, median subfoveal choroidal thickness (286 mm [IQR 226-372 mm]) was significantly thicker than subfoveal choroidal thickness in myopic, non-CSC patients (200 mm [IQR 152-228 mm], P , 0.001) but thinner than emmetropic patients with CSC (452 mm [IQR 342-538 mm], P , 0.001). They also had pachyvessels in 70% of the eyes comparable with emmetropic CSC (76%, P = 0.70). Choroidal hyperpermeability was frequently present on indocyanine green angiography in both myopic and emmetropic CSC eyes. Need for treatment, treatment success, and recurrence rate were not significantly different between CSC groups. Conclusion: Myopic CSC presents with similar imaging and clinical characteristics as emmetropic CSC, apart from their thinner choroids. Keeping in mind the structural changes of myopia, other imaging characteristics could aid the diagnostic process.
