Optical coherence tomography of central serous chorioretinopathy

Objective To evaluate the morphological characteristic of optical coherence tomography (OCT) in acute and recovery phase of central serous chorioretinopathy (CSC). Methods Sixty-five cases of CSC were examined by optical coherence tomography. OCT was performed in acute phase with subjective symptoms occurring in 4-8 weeks and in recovery phase, respectively. Results OCT in the acute phase of CSC showed a vaulted elevation in retina at the central fovea with an optically clear space which was consistent with serous detachment of neurosensory retina caused by subretinal fluid accumulation, manifested as detachment of neurosensory and retinal pigment epithelium and rupture of pigment epithelium. The last OCT in the recovery phase of CSC showed absorption of serous fluid in the neuroepithelium. The central fovea of macula became thinner in some patients. Regular follow-up OCT showed serous fluid absorption and decreased detachment of neuroepithelium in l5 patients. Conclusion OCT can show the direct images of CSC and quantitatively monitor the clinical course of serous retinal detachment, and is, therefore, of important significance for the change in CSC during follow-up.
