Purpose:
To report the results of repeated bilateral sequential photodynamic therapy (PDT) with verteporfin for sub-retinal neovascularization associated with parafoveal telengiectasia.
Design:
Interventional case series.
Methods:
Three patients (minimum of 6-month follow-up) were analyzed after bilateral sequential PDT for parafoveal telengiectasia-associated sub-retinal neovascularization.
Results:
Mean age was 53.3 +/- 2.1 years. Mean and median follow-up duration were 12.3 and 10 months, respectively. Mean initial Early Treatment of Diabetic Retinopathy Study chart letter acuity was 30.6 in right eyes and 19 in left eyes, and at month 6, it was 30.6 in right eyes and 22.3 in left eyes. All patients received bilateral treatment three times; one eye received a fourth treatment. The greatest linear diameter was between 2310 and 5400 microm.
Conclusion:
PDT is a viable treatment for sub-retinal neovascularization associated with parafoveal telengiectasia. Bilateral sequential treatment is a convenient way to treat bilateral disease.
