To evaluate the 12-month visual outcome of photodynamic therapy with verteporfin (PDT-V) for patients with subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration and to verify the predictive role of visual and angiographic factors.


This retrospective, interventional, consecutive case series study included subjects with different forms of subfoveal CNV. All patients received PDT-V according to Treatment of Age-Related Macular Degeneration With Photodynamic Therapy/Visudyne in Photodynamic Therapy guidelines. A review of medical and angiographic records was performed.


Two hundred sixteen patients were divided into 4 study groups: group I, 60 eyes with classic CNV; group II, 56 eyes with predominantly classic CNV; group III, 42 eyes with minimally classic CNV; and group IV, 58 eyes with occult CNV. In groups I and II, best-corrected visual acuity (BCVA) was moderately decreased, without reaching a statistically noticeable level during the entire follow-up; lesion size reduction only reached significance in group I. Groups III and IV showed evident worsening of BCVA (P < 0.05), despite concomitant reduction in CNV size (statistically remarkable only for occult CNV). All study groups exhibited a significant correlation between higher baseline BCVA and better final visual outcome. In groups II and IV, smaller baseline CNV sizes also favorably influenced final BCVA.


Standardized PDT-V minimizes deterioration of central vision only in patients with classic and predominantly classic CNV. Irrespective of the CNV type, better BCVA at presentation represents a good predictive sign. In predominantly classic and occult lesions, minor initial CNV dimension is also a positive prognostic element.
