Temporary Exudative Retinal Detachment following Photodynamic Therapy in a Patient with Retinal Capillary Hemangioblastoma.

A 21-year-old male with von Hippel-Lindau syndrome was treated for a retinal hemangioblastoma with photodynamic therapy (PDT). We employed the standard PDT protocol with doubled treatment duration. Seven days after the procedure, there were some perilesional intra- and subretinal hemorrhages and significant exudative retinal detachment extending inferiorly. Four weeks later, the hemorrhages had mostly cleared, and diminished subretinal fluid and partial regression of the hemangioblastoma were noted. PDT might induce temporary subretinal fluid accumulation in eyes with retinal hemangiomas.
