PERIPAPILLARY CHOROIDAL THICKNESS IN CENTRAL SEROUS CHORIORETINOPATHY: Is Choroid Outside the Macula Also Thick?

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 μm) and fellow eyes (316.18 ± 54.68 μm) of the patient group were thicker than those of the normal controls (281.90 ± 40.97 μm, 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 μm) and fellow eyes (206.66 ± 59.35 μm) of the patient group compared with the normal controls (179.52 ± 39.64 μm, 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.
