Photodynamic therapy for choroidal neovascularisation secondary to basal laminar drusen

Abstract

Basal laminar drusen (BLD) is a rare retinal disorder that may be complicated with choroidal neovascularisation (CNV). Here we describe four patients treated with verteporfin photodynamic therapy (PDT) for CNV secondary to BLD. Four consecutive patients presented with subfoveal CNV secondary to BLD. Mean visual acuity was 20/50. CNV was treated with one single PDT session. Exsudative features of CNV were resolved after one session for all patients. After 6 months, mean visual acuity was 20/25 and remained stable. In this series, PDT was an effective treatment for CNV secondary to BLD.
