Bilateral serous retinal detachment associated with subretinal fibrin-like material in a case of pregnancy-induced hypertension

PURPOSE: To describe a case of bilateral serous retinal detachment (SRD) associated with subretinal fibrin-like material (SRFM) in pregnancy-induced hypertension (PIH). OBSERVATIONS: Angiography of a 31-year-old primigravida with PIH who developed acute bilateral SRD with SRFM after caesarean section showed choroidal hypoperfusion and dye leakage. Optical coherence tomography revealed irregularity of the ellipsoid zone and retinal pigment epithelium. The patient's visual acuity was hand motion in the both eyes at the initial examination. After 30 days, SRD and SRFM spontaneously disappeared. Moreover, the EZ returned and the visual acuity significantly improved to 20/25 in the right and 20/20 in the left eye. CONCLUSIONS AND IMPORTANCE: Although there are reports on central serous chorioretinopathy or Vogt–Koyanagi–Harada disease, there have been no studies on SRFM complications in patients with PIH. In the current case, we speculated that SRFM was associated with acute intense choroidal ischemia and inflammation secondary to this ischemic condition. Distinguishing whether inflammation necessitating treatment is involved in SRFM may be difficult. Short observation intervals and frequent examinations are important to ensure that treatment timings are not missed.
