Abstract

Background/aim We previously reported that ranibizumab performed better on visual prognosis than photodynamic therapy (PDT) in a Ranibizumab (Lucentis) And Photodynamic Therapy On Polypoidal choroidal vasculopathy (LAPTOP) study. To determine if the first-choice treatment, either PDT or intravitreal ranibizumab, has a long-term effect in patients with polypoidal choroidal vasculopathy (PCV).

Methods We reviewed medical records of patients randomised to either PDT (29 eyes) or ranibizumab (27 eyes) from July 2009 to June 2011 in LAPTOP study. Retreatment or switching to other treatments were at the investigator’s discretion after release from the 2-year LAPTOP study up to 5 years. We evaluated visual acuity (VA), continuity of initial treatment, percentage of dry macula achievement and macular atrophy at 5 years.

Results The logarithm of minimal angle of resolution VA was 0.56 in the PDT and 0.44 in the ranibizumab groups at baseline (p=0.101) and was 0.55 and 0.28 at 5 years, respectively (p<0.05). More than 70% of the patients converted to aflibercept in following years. Achievement percentages of dry macula were 74% (PDT) and 63% (ranibizumab) at 5 years, and macular atrophy was detected in 78% (PDT) and 60% (ranibizumab) with a mean area of 7.7 and 3.5 mm2, respectively (p=0.155).

Conclusions The better VA in the initial ranibizumab group compared with the PDT group at 2 years was retained at the 5-year follow-up.
