Hair dye’s aromatic amines lead to blurred vision lasting four months: case

A 61-year-old woman developed bilateral blurry vision shortly after using hair dye, due to the aromatic amines in the product, French doctors say.
The patient had no relevant medical history, no exposure to corticosteroids, and used a commercially available hair dye containing para-phenylenediamine, according to the case in JAMA Ophthalmology.
On examination, visual acuity was slightly reduced in the right eye (20/40) but normal in the left.
Fundus examination revealed multiple serous retinal detachments, primarily in the posterior region, while optical coherence tomography (OCT) imaging showed retinal thickening.
