Morphological changes in the retinal pigment epithelium on spectral-domain OCT in the unaffected eyes with idiopathic central serous chorioretinopathy.

PURPOSE

To report the changes seen in the retinal pigment epithelium (RPE) morphology in the asymptomatic eyes of patients with idiopathic central serous chorioretinopathy (ICSC) using spectral-domain Cirrus (TM) high-definition optical coherence tomography (HD-OCT).

METHODS

In a prospective case series, 17 consecutive patients with unilateral ICSC underwent spectral-domain Cirrus (TM) HD-OCT scans for both affected and opposite asymptomatic eye. Three-dimensional single-layer RPE map was studied in both eyes for morphological alterations, and findings were correlated with clinical presentation, fluorescein angiogram, and 5 Line raster scan. Additionally, three-dimensional (3D) single-layer RPE maps done in 111 healthy volunteers served as control.

RESULTS

In patients with ICSC, 3D single-layer RPE analysis of asymptomatic eyes showed presence of RPE bumps in 16 (94%) eyes and pigment epithelium detachment (PED) in 2 (11.8%) eyes. The 5 Line raster scan was normal in all eyes. Of 222 normal (control) scans, 18 showed RPE bumps and none showed PED. Conclusions 3D single-layer RPE map showed abnormal pattern in the asymptomatic eyes of patients with unilateral ICSC.

SUMMARY

Spectral-domain optical coherence tomography showed morphologic alterations in retinal pigment epithelium in both eyes of patients with idiopathic central serous chorioretinopathy.
