Treatment of corneal thinning Keratoconus is the most common form of Corneal ectasia, a progressive thinning of the cornea. The condition is treated by corneal collagen cross-linking, which increases corneal stiffness. Cross-linking is achieved by applying a topical<unk>  solution to the cornea, which is then exposed to ultraviolet A light. Migraine prevention In its 2012 guidelines, the American Academy of Neurology stated that high-dose<unk>  (400 mg) is "probably effective and should be considered for migraine prevention," a recommendation also provided by the UK National Migraine Centre. A 2017 review reported that daily<unk>  taken at 400 mg per day for at least three months may reduce the frequency of migraine headaches in adults. Research on high-dose<unk>  for migraine prevention or treatment in children and adolescents is inconclusive, and so supplements are not recommended. Food coloring<unk>  is used as a food coloring (yellow-orange crystalline powder), and is designated with the E number, E101, in Europe for use as a food additive.
