Purpose: To investigate peripapillary choroidal thickness (CT) outside the macula in central serous chorioretinopathy (CSC). Methods: We reviewed the medical records of 34 patients with unilaterally symptomatic idiopathic CSC and 34 age-matched controls. Subfoveal and peripapillary CT were measured from images obtained by spectral domain optical coherence tomography. The nasal peripapillary CT of the choroid outside the macula was determined. Results: The subfoveal CT of CSC (369.74 ± 54.17 m) and fellow eyes (316.18 ± 54.68 m) of the patient group were thicker than those of the normal controls (281.90 ± 40.97 m, all P < 0.05). The subfoveal CT in CSC was significantly thicker than those in the fellow eyes. Nasal CT was also thicker in CSC (217.59 ± 62.03 m) and fellow eyes (206.66 ± 59.35 m) of the patient group compared with the normal controls (179.52 ± 39.64 m, all P < 0.05). However, there was no difference in nasal CT between CSC and fellow eyes (P 0.150). Conclusion: This result may suggest that manifest CSC occurs in patients with thick choroids both within and outside the macula, especially when subfoveal CT is increased.
