[Choroidal haemangioma worsens after laser therapy for skin port-wine nevus and improves with photodynamic therapy in the eye].

A young man with facial port-wine nevus on one side of his face underwent skin laser treatment on his facial lesions and experienced worsening visual acuity from 0.9 to 0.4 and metamorphosis afterwards in the ipsilateral eye. He was found to have a choroidal haemangioma with an exudative retinal detachment. He received photodynamic therapy resulting in resolution of subretinal fluid and shrinkage of the haemangioma. Visual acuity decreased to 0.1 one week following photodynamic treatment, but improved steadily after that. Nine months following the treatment the visual acuity is 0.5 and metamorphosis is absent.
