Credit: SWNS Chandler Plantebr br 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.br br 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. br br She hasn't received any official diagnosis for her ongoing health problems - which include frequent strokes, head and face inflammation. br br Her doctors have speculated it could be down to an autoimmune condition - even a "really severe" version of long covid. br br She's been through multiple rounds of radiation, courses of steroids and chemo drugs - and will need to take aspirin daily for the rest of her life to prevent the strokes from coming back.
