Blind spot enlargement: A differential diagnosis challenge

Aristotelis Karamaounas et al. Saudi J Ophthalmol. .

Abstract

A 39-year-old woman, without any systemic or ocular history, presented with a paracentral scotoma in her right eye with normal visual acuity. Humphrey's visual fields showed a reversible enlargement of the right blind spot. The final diagnosis was acute idiopathic blind spot enlargement which was successfully treated with intravenous steroids. Although differential diagnosis of blind spot enlargement can be challenging, multimodal imaging with combination of visual field's assessment can help us make the right diagnosis.

Keywords: Acute idiopathic blind spot enlargement; multiple evanescent white dot syndrome; white dot syndrome.
