UNILATERAL CHEMOSIS, BULLOUS SEROUS RETINAL DETACHMENT, AND PRESUMED BACILLARY LAYER DETACHMENT IN SEVERE PREECLAMPSIA.

BACKGROUND/PURPOSE: To report a case of unilateral chemosis, serous retinal detachment (SRD), and presumed bacillary layer detachment in pregnancy. METHODS: Clinical examination and multimodal imaging findings were reviewed and analyzed. RESULTS: A 17-year-old female patient with severe preeclampsia was found to have unilateral chemosis and bullous SRD. Postpartum optical coherence tomography revealed thickened choroid and presumed bacillary layer detachment. Two weeks later, chemosis and SRD resolved, leaving behind mottled hyperpigmentation, drusen, and subretinal drusenoid deposits. CONCLUSION: The combination of chemosis and SRD in preeclampsia is exceedingly, rare and it has never previously been reported to occur unilaterally. With delivery, visual acuity, chemosis, choroidal thickness, and SRD all normalize.
