Effects of combination therapy with verteporfin photodynamic therapy and ranibizumab in patients with age-related macular degeneration.
OBJECTIVE
This open-label, prospective, small-scale study investigated the benefits of same-day verteporfin and intravitreal ranibizumab in patients with predominantly classic, minimally classic or occult subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration.


METHODS
Patients received verteporfin at baseline and at month 3, if leakage persisted. Ranibizumab (0.5 mg) was given at baseline and months 1, 2 and 3, and thereafter at monthly intervals if required. Same-day ranibizumab was given ≥ 1 hr after verteporfin.


RESULTS
Fifteen patients [11 male, four female; mean age 75.5 years (range 54-94 years)] were treated. At day 360, mean visual acuity (VA) had improved by 10.9 letters. An increase of ≥ 15 and ≥ 30 letters (i.e. ≥ 3 and ≥ 6 lines) was observed in seven (47%) patients and one patient (7%), respectively. Mean central retinal thickness (CRT) decreased by 85 μm. At days 7, 14 and 30, CNV perfusion was absent in 14/15 patients. Mean lesion area had reduced from baseline by 23.1% at day 120, 25.5% at day 180 and 23.6% at day 360. There were no visual safety concerns and intraocular pressures remained normal. Only two serious adverse events were recorded over the 12-month period, and neither was considered to be related to treatment.


CONCLUSIONS
Same-day verteporfin plus ranibizumab improved VA, reduced CRT, prevented CNV perfusion and reduced lesion area safely over 12 months. Further investigation is warranted to confirm whether this combination improves long-term vision and reduces the need for retreatment.
