Presentation transcript:

Photographs of the optic nerve of a 20-year-old woman, showing severe bilateral optic disc edema at presentation. Photographs of the optic nerve of a 20-year-old woman, showing severe bilateral optic disc edema at presentation. The edema substantially improved after ventriculoperitoneal (VP) shunt, as seen in the 1-week and 1-month follow-up images. Humphrey 24–2 visual fields at presentation show enlarged blind spots (blue arrows) and nasal steps (red arrows) in both eyes. These visual field defects substantially improved at the follow-up visits. Andrew Micieli, and Jonathan A. Micieli CMAJ 2019;191:E639 ©2019 by Canadian Medical Association
