Cushing's syndrome caused by use of synthetic ocular steroid.

WHAT IS KNOWN AND OBJECTIVE: Cases of Cushing's syndrome (CS) following ocular steroid use have been reported in recent years, albeit rarely.

CASE DESCRIPTION: We report a case of iatrogenic CS in a child induced by fluorometholone-containing eyedrops. Our patient was referred to our endocrinology clinic due to rapid weight gain. His history revealed that 1.5 months previously he had been started on fluorometholone eyedrops.

WHAT IS NEW AND CONCLUSION: To the best of our knowledge, no cases of CS have been reported following ocular fluorometholone use. Although eyedrops containing potent glucocorticoids may lead to CS, fluorometholone, a relatively less potent steroid, may also cause the syndrome, as in our case.
