[Photodynamic therapy in retinal pigment epithelium detachment associated with long term central serous chorioretinopathy].

PURPOSE
To present a case of long term central serous corioretinopathy associated with chronic detachment of the retinal pigment epithelium (RPE) and the effect of photodynamic therapy on it.


CASE CLINIC
We present the case of a 46-year old man with long term chronic central serous chorioretinopathy (18 mo.) with chronic detachment of RPE in his left eye who underwent PDT with Verteporfin (Visudyne). BCVA improved from 0.7 to 1 and metamorphopsia disappeared within one month of treatment. The patient remained asymptomatic for a follow-up period of 15 months.


DISCUSSION
Choroidal hyperpermeability is found in central serous chorioretinopathy as a primary involvement factor. PDT with Verteporfin induces a transient reduction in choriocapilaris blood flow and can be used as treatment in cases of chronic central serous chorioretinopathy.
