PARACENTRAL ACUTE MIDDLE MACULOPATHY IN PREGNANCY

To describe a case of paracentral acute middle maculopathy (PAMM) during the first trimester of pregnancy without other ocular or systemic comorbidities.

Case report.

A 31-year-old woman in her first trimester of pregnancy presented with a paracentral scotoma in the absence of other retinal pathology or systemic associations. Optical coherence tomography showed a classic acute PAMM lesion, and optical coherence tomography angiography showed preservation of vascular flow in the area of the PAMM lesion 1 week after symptom onset. Subsequent workup for underlying systemic disease that can affect the retinal vasculature was negative.

Paracentral acute middle maculopathy lesions have been described in eyes with retinal vascular disease and in people with systemic vascular diseases or events. This is the first described case of a PAMM lesion in the absence of associated factors other than an uncomplicated pregnancy.
