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

To investigate peripapillary choroidal thickness (CT) outside the macula in central serous chorioretinopathy (CSC).

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.

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).

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.
