Multimodal imaging findings in a case of severe Central Serous Chorioretinopathy in an uncomplicated pregnancy

Background: Central Serous Chorioretinopathy (CSC) has been previously reported as an infrequent complication of pregnancy that usually resolves spontaneously after delivery, with minimal or no sequel. We report a case of a severe form of CSC in an uncomplicated pregnancy with extensive subfoveal exudates and severe permanent visual loss. Multimodal imaging techniques, including color and red-free photographs, near-infrared reflectance, fluorescein angiography, and spectral-domain optical coherence tomography, were performed and the findings were correlated to the changes in visual acuity. Case presentation: A 35-year-old pregnant woman presented with loss of vision and metamorphopsia in her left eye. Fundus examination showed subfoveal severe exudation with a posterior pole serous detachment. Optical coherence tomography (OCT) showed macular neurosensory detachment with central highly reflective sub-retinal material. Multimodal fundus pictures and angiograms revealed distinct clinical features of the disease during both the acute and final phase. The disease spontaneously resolved after delivery with regression of the subretinal fluid and the disappearance of subfoveal exudates. Nevertheless, because of severe atrophic macular changes and subfoveal fibrosis, no improvement of visual acuity was noted. Conclusion: Severe variants of CSC may also present in cases of uncomplicated pregnancy and result in a poor prognosis. Recognising these presentations of CSC is critical to avoid improper management. Multimodal imaging may help to clarify the diagnosis and highlight the clinical features.
