Purpose:
The aim of this study is to evaluate the results of indocyanine green (ICG) angiography guided photodynamic therapy (PDT) in patients with chronic central serous chorioretinopathy (CSR).
Methods:
Eleven eyes of 11 patients with symptomatic chronic multifocal CSR underwent ICG angiography guided PDT. Visual acuity testing, systemic ophthalmologic examination, color photographs, fluorescein angiography (FFA), ICG and optical coherence tomography (OCT) were used to evaluate the results of PDT. Indications for retreatment were presence of hyperfluorescence spot in ICG angiography and subretinal fluid in OCT.
Results:
Follow up ranged 6 to 12 months with mean 7.6±2.4 months. No deterioration in visual acuity was observed in any case during follow-up. At 6 month of follow-up, five eyes (%45) had no change in visual acuity and 6 eyes (55%) had gained 1 or more lines of vision. During follow-up no systemic or ocular complication were encounted.
Conclusion:
ICG angiography guided PDT seems to aid in the resolution of serous retinal detachment in patients with chronic CSR. As the sample size is small and the follow up period is short in our study, further trials of ICG angiography guided PDT for choronic CSR are required to show long term results.
