Objective

To report a case of subretinal fibrosis-mimicking a chorioretinal anastomosis following photodynamic therapy (PDT) of an idiopathic choroidal neovascularization (CNV).

Methods

We report a case of a 25-year-old woman who developed a subfoveal idiopathic CNV following pregnancy. After two PDT-treatments, the subretinal fibrosis increased and a chorioretinal anastomosis was diagnosed. The visual acuity decreased to 20/100 and fluoresceine angiography revealed persistent activity. A vitrectomy with excision of the CNV was performed.

Results

Intraoperatively, a subretinal fibrosis presented with synechiae and traction to retinal vessels with the temporal upper vein being pulled into the choroid. One year after surgery, the visual acuity was 20/25 with a stable fixation despite a central retinal pigment epithelium defect and surrounding visual field defect and without any signs of recurrence.

Conclusions

A chorioretinal anastomosis can have clinical and angiographic aspects similar to a subretinal fibrosis. This has to be taken into consideration in the differential diagnosis of suspected chorioretinal anastomosis.
