The eyes have it - 2012
The common causes are atopic eczema and a developing contact dermatitis. The latter can be due to something applied to the eyelids (e.g. cosmetics or a shampoo), but usually it is due to an allergen transferred from the fingers. Eyelid skin is very thin hence allergens can easily cross it and elicit a reaction while the fingers remain unaffected. The thinness also means topical steroid creams can also cross easily, raising the issue of causing or exacerbating glaucoma. Avoid using strong topical steroids here. Hydrocortisone (as acetate) eye ointment is perfectly adequate with lower risk.
