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 metamorphopsia 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 metamorphopsia is absent.

 

 

Figure 1. A. Prior to photodynamic therapy, optical coherence tomography shows a serous retinal detachment of the macula which measures 709 µm in thickness.

 

B. Nine months after photodynamic therapy optical coherence tomography shows that the thickness of the retina has decreased to 197 µm.

 

Figure 2. A. Fundus photography prior to photodynamic therapy shows pigmentary clumping in the macula.  The choroidal haemangioma is not easily detected on a two-dimensional fundus photography.

 

B. Fundus photography 9 months after the photodynamic therapy shows pigmental scarring and the choroidal haemangioma has subsided although it is not easily detected.

 

Figure 3. Fluorescein angiography prior to photodynamic therapy shows a well defined choroideal haemangioma in the central part of the macula right under the fovea.
