ABSTRACT Cortical blindness is an uncommon, but dramatic, complication of preeclampsia. We present a case in which diffusion-weighted magnetic resonance imaging played a critical role in determining the etiology of the cortical blindness and its subsequent management.

    ABSTRACT: In the past three decades, there have been countless advances in imaging modalities that have revolutionized evaluation, management, and treatment of neuro-ophthalmic disorders. Non-invasive approaches for early detection and monitoring of treatments have decreased morbidity and mortality. Understanding of basic methods of imaging techniques and choice of imaging modalities in cases encountered in neuro-ophthalmology clinic is critical for proper evaluation of patients. Two main imaging modalities that are often used are computed tomography (CT) and magnetic resonance imaging (MRI). However, variations of these modalities and appropriate location of imaging must be considered in each clinical scenario. In this article, we review and summarize the best neuroimaging studies for specific neuro-ophthalmic indications and the diagnostic radiographic findings for important clinical entities.

    ABSTRACT: Three Afro-Caribbean women presented with a decreased visual acuity associated with preeclampsia during the third trimester of pregnancy. Fundus examination exhibited a serous retinal detachment (SRD). Postpartum fluorescein and indocyanine green angiography indicated subretinal leakage induced by choroidal ischemia. The three patients had an improvement of their visual acuity to 20/20 within 2 to 3 months of the onset of symptoms. Fundus exam and fluorescein angiography showed no further abnormality. SRD in preeclampsia may have an impressive acute presentation but seems to resolve favorably spontaneously without intervention, upon delivery. Nevertheless, SRD must be considered to be a sign of imminent worsening of preeclampsia.
