title: Unfavorable effect of photodynamic therapy for late subretinal neovascularization with chorioretinal anastomoses associatedwith idiopathic multiple serous detachments of the retinal pigment epithelium.
abstract: OBJECTIVE
  To describe a case of a 46-year-old woman with an asymptomatic history of unilateral multiple serous detachments of the retinal pigment epithelium (PED) in the right eye, treated with photodynamic therapy (PDT) with verteporfin for recent onset of subfoveal choroidal neovascularization (CNV) with chorioretinal anastomoses (CRA).

  RESULTS
  Fluorescein and indocyanine green (ICG) angiography, performed with a Heidelberg scanning laser ophthalmoscope (SLO), demonstrated a predominantly classic foveal choroidal neovascular membrane associated with a PED and 1 one retinal and 2 two venous chorioretinal anastomoses. The left fundus was normal. PDT therapy was performed according to standard techniques. Three PDT treatments were performed at an interval of 3 months. Three months after the second PDT, visual acuity dropped to 20/200, with an en-largement of the neovascular network. One month after the third treatment, visual acuity deteriorated further and the CRA appeared enlarged, associated with a dense fibrotic re-action in the centere of the lesion.
  
  
  CONCLUSIONS
  This clinical observation demonstrates that idiopathic serous detachments of the retinal pigment epithelium may represent predisposing changes to CNV development, and in the case CNV is associated with CRA, PDT may be unsuccessful. (Eur J Ophthalmol 2004; 14: 568-71).
