A French girl’s dye job inadvertently turned out to be perilous for her imaginative and prescient. In a brand new case report this week, the lady’s medical doctors describe how she started to expertise retinal detachment and imaginative and prescient loss quickly after utilizing hair dye containing sure chemical substances. Fortunately, her eyesight returned to regular over time as soon as she stopped utilizing the product and he or she was capable of proceed safely coloring her hair utilizing completely different components.
Docs on the Edouard Herriot Hospital and the LEO Ophthalmological Heart in France reported the eye-catching medical story Thursday within the journal JAMA Ophthalmology. In accordance with the paper, the 61-year-old girl visited the medical doctors a number of days into creating blurry imaginative and prescient in each eyes. Checks confirmed that her signs have been brought on by injury to her retinas—the layers of cells behind the attention that seize gentle and convert it into the knowledge wanted for us and our brains to course of imaginative and prescient.
The girl had no present medical historical past that will clarify this retinal injury, also called retinopathy, and the medical doctors failed to seek out different widespread causes of it of their checks, akin to an infection or most cancers. However the girl did point out that simply earlier than her signs started, she had lately used a store-bought hair dye that contained the chemical para-phenylenediamine.
Para-phenylenediamine belongs to a gaggle of chemical substances referred to as fragrant amines. And as luck would have it, the medical doctors have been conscious of different latest circumstances of middle-aged girls experiencing retinopathy related to using hair dye containing fragrant amines (shortened to RAHDAA). Given the timing of her eye bother, and the shortage of some other clear various rationalization, they decided that the lady had developed her personal case of RAHDAA.
RAHDAA resembles one other type of retinopathy tied to using anti-cancer medication that inhibit the exercise of MEK proteins. Each these medication and fragrant amines could trigger retinal injury by interfering with a pathway necessary to the survival and homeostasis of retinal pigment epithelial cells, the authors say. The situation does seem like uncommon, although individuals who have scalp wounds whereas utilizing hair dyes with fragrant amines might be at increased danger, based mostly on case experiences (the lady on this case didn’t have such wounds).
As for the lady, her story has an eventual comfortable ending. She instantly stopped utilizing the dye, and inside 4 months time, her imaginative and prescient returned to regular, with no signal of retinal detachment. At a check-up 4 years later, the lady reported that she had switched to amine-free hair dye and checks confirmed that her imaginative and prescient remained nearly as good as ever, although she did appear to nonetheless have some lingering, if asymptomatic, adjustments in her retina brought on by the dye.
Whereas these circumstances are “presumably uncommon,” the report authors say that different medical doctors ought to concentrate on this situation and prepared to contemplate amine-containing dyes as a attainable reason behind their affected person’s retina points, particularly when preliminary checks fail to seek out some other clear reply.
