A case of bilateral iris mammillations with unusual pupillary appearance and pseudo‐hypertension

Abstract

Iris mammillations are congenital abnormalities characterised by villiform elevations regularly spaced on the surface of the iris. The aetiology of iris mammillations is unknown. They can be either isolated or associated with melanocytosis involving the uveal tract and the periocular tissue, resulting in a risk for uveal melanoma. These lesions can be complicated by high intraocular pressure and, in the case of associated melanocytosis of the iris, sclera or periocular tissues, by uveal melanoma. Patients with iris mammillations should be followed regularly due to these potential complications.We report a case of bilateral iris mammillations with unusual pupillary appearance and pseudo‐hypertension and emphasise the importance of iris mammillations and that central corneal thickness should be considered when intraocular pressure is measured.
