Sir,
I read with interest the article by Silva et al.1 The authors are not aware of corticosteroids usage in the study. Although corticosteroids may be used to treat Graves' orbitopathy,2 such medications are also associated with increased intraocular pressure and glaucoma.3 Failure to consider this, would bias the frequency of ocular hypertension and glaucoma in patients diagnosed with Graves' orbitopathy.
Conflict of interest
The author declares no conflict of interest.
