A woman who had to have stents implanted in her brain due to a "mystery illness" permanently lost vision in her right eye - after the stents "choked out" her optic nerve.

Chandler Plante, 23, suffered a stroke in March 2021 and lost all vision in her right eye eight months later. While the vision loss wasn't caused by the stroke, it happened as a result of her treatment.

She hasn't received any official diagnosis for her ongoing health problems - which include frequent strokes, head and face inflammation.

Her doctors have speculated it could be down to an autoimmune condition - even a "really severe" version of long covid.
