Location of Port-Wine Stains and Likelihood of Complications

To the Editor.—

I read with interest Location of Port-Wine Stains and the Likelihood of Ophthalmic and/or Central Nervous System Complications by Tallman et al.¹ Knowing the incidence of complications in patients with port-wine stains (PWS) is important, both for counseling families regarding risks and for justifying screening recommendations. Although the article provides some useful information, I feel that further comment is warranted.

The authors found a 7% incidence of glaucoma in patients with PWS in the trigeminal distribution (18 of 274 patients).
