What is generally considered a side effect of prolonged topical steroid use?

Prolonged use of topical steroids is commonly associated with an increase in intraocular pressure (IOP). This occurs because corticosteroids can induce changes in the outflow of aqueous humor, leading to elevated pressure within the eye. The mechanism involves a decrease in the aqueous humor drainage through the trabecular meshwork, which can be particularly problematic for individuals who are predisposed to glaucoma or already have elevated IOP.

While other options like corneal thinning, retinal detachment, and optic nerve damage may be related to other conditions or treatments, they are not direct or common side effects specifically associated with topical steroid use. Corneal thinning, for example, is more typically associated with conditions involving excessive exposure to steroids over an extended period or may occur with oral steroids. Retinal detachment and optic nerve damage, while serious concerns in ocular health, are not typically linked to the use of topical steroids. Thus, the increase in intraocular pressure is a well-documented and recognized side effect of prolonged topical steroid therapy, highlighting the need for careful monitoring of IOP in patients undergoing such treatment.
