    Abstract:
    BACKGROUND: Our aim was to evaluate the short-term safety and efficacy of combined photodynamic therapy (PDT) with verteporfin and intravitreal bevacizumab in neovascular age-related macular degeneration (AMD). METHODS: A prospective non-randomized interventional case series of 30 eyes of 30 patients with choroidal neovascularization (CNV) caused by AMD was studied. All patients were treated with PDT followed by an intravitreal injection of bevacizumab (1.5 mg) on the same day. Ophthalmic evaluations included determination of best-corrected visual acuity by using ETDRS charts. CNV lesion characteristics were determined by fluorescein angiography, and retinal morphology by optical coherence tomography. Review examinations were performed 1, 4, and 12 weeks following treatment. RESULTS: The median ETDRS letter scores increased by 3 letters after 4 weeks and 4.3 letters after 12 weeks. Median central retinal thickness decreased from the baseline by 145 microm (week 1), 205 microm (week 4), and 171 microm (week 12), respectively (P < 0.0001, for all comparisons). One patient experienced a transient moderate vision loss after 4 weeks post treatment. Leakage on fluorescein angiography was resolved in all patients at week 12. No significant ocular or systemic side-effects were observed. CONCLUSIONS: Short-term results suggest that a single PDT in combination with intravitreal bevacizumab is safe and associated with stabilization of visual acuity and decrease of intraretinal and subretinal fluid accumulation in the macula. Further evaluation of this treatment strategy for neovascular AMD appears warranted.
