The Science behind the Tip
30-40% of the population respond to topical steroids by increasing their IOP (1). A steroid response is commonly found in patients with glaucoma. Other risk factors include a family history of glaucoma, diabetes and high myopia (1). Children are particularly susceptible to an IOP increase secondary to steroid eyedrops, with more than 60% exhibiting this response (2).
The reason for this phenomenon is not known, but increased resistance to aqueous outflow through an effect on the extra-cellular matrix or endothelial cells of the trabecular meshwork presumably plays a role (1,2). Children taking topical steroids for allergic conjunctivitis should have their IOP regularly checked to avoid the development of secondary glaucoma and visual loss (3).
