Photodynamic therapy combined with systemic corticosteroids for choroidal neovascularisation secondary to punctate inner choroidopathy.

摘要

AimTo report on visual acuity (VA) and angiographic outcomes in patients presenting with subfoveal choroidal neovascular membranes (CNV) secondary to punctate inner choroidopathy (PIC), treated with photodynamic therapy (PDT) with verteporfin combined with systemic corticosteroids.MethodsA prospective case series of patients with subfoveal CNV secondary to PIC was analysed. All patients were treated with PDT combined with oral prednisolone (1 mg/kg body weight/day) which was started 5 days before PDT. Fluorescein angiography was performed at baseline and every 3 months post-treatment to establish the size, position, and activity of the CNV. Visual acuity was measured using the ETDRS scale. Further PDT treatment was carried out at follow-up visits if there was angiographic evidence of ongoing CNV activity.ResultsFive female patients with a mean age of 30.4 years (range 25-43 years) were treated over a 12-month period. The mean greatest linear diameter (GLD) of the CNV was 1.66 mm (range 0.46-3.28 mm). Amean improvement in vision of nine ETDRS letters (range -15-20 letters) after treatment was found, which was maintained at final follow-up. The mean follow-up time was 12 months (range 10-14 months). The mean number of PDT treatments was two (range 1-3).Conclusions:The vaso-occlusive effect of PDT combined with the vasostatic and anti-inflammatory effect of systemic oral prednisolone appears to be a safe and effective option in the primary treatment of subfoveal CNV in patients with PIC.Eye (2008) 22, 528-533; doi:10.1038/sj.eye.6702688; published online 19 January 2007.
