Purpose  

To report the presence and disappearance of subretinal fibrinous exudate in pregnancy-induced central serous chorioretinopathy studied with optical coherence tomography (OCT).

Methods  

Case report. A 32-year-old woman was referred for ophthalmoscopic evaluation in her 32nd week of pregnancy, complaining of reduced vision in her right eye.

Results  

The funduscopic examination revealed a serous detachment of the macula with subretinal exudative deposits in the right eye and a peripapillary serous detachment in the left eye. OCT sections through the right macula demonstrated serous elevation of the retina and the presence of highly reflective material in the subretinal space. Two weeks after delivery, OCT showed resolution of subretinal fluid and the disappearance of submacular exudate in the right eye.

Conclusion  

During pregnancy and immediately after delivery, OCT may provide information reflecting the relationship between the retina, subretinal space, and retinal pigment epithelium without any known adverse effects to the infant. In a patient with pregnancy-associated central serous chorioretinopathy, a highly reflective material, presumably fibrin, was detected spanning the subretinal space that was subsequently shown to disappear. This information may help us better understand the pathological retinal changes that may occur during pregnancy.
