What potential side effect should patients on hydrocortisone be made aware of regarding their vision?

Patients being treated with hydrocortisone should be made aware that cataracts may develop as a potential side effect of corticosteroid therapy. Hydrocortisone, which is a potent anti-inflammatory and immunosuppressive agent, can contribute to the formation of cataracts, particularly with prolonged use or in higher doses. This risk is often significant enough that it warrants annual eye examinations with an optometrist or ophthalmologist to monitor for any changes in vision or the development of cataracts. Early detection through regular eye exams can help manage and mitigate the effects on vision before they become more severe.

The other potential options do not accurately reflect the common ocular side effects associated with hydrocortisone therapy. This makes cataracts the primary concern when considering the impact of prolonged corticosteroid use on a patient's vision.
