The Claim

Photodynamic therapy combined with ranibizumab achieves complete polyp regression in up to 77.8% of treatment-naïve polypoidal choroidal vasculopathy patients, which is significantly higher than the 26.7–34.7% rate observed with ranibizumab monotherapy.

In plain English

In patients with polypoidal choroidal vasculopathy who have not received prior treatment, combining photodynamic therapy with ranibizumab results in complete polyp regression in up to 77.8% of cases, while ranibizumab alone results in regression in 26.7–34.7% of cases.

See the scientific wording

Photodynamic therapy combined with ranibizumab achieves complete polyp regression in up to 77.8% of treatment-naïve polypoidal choroidal vasculopathy patients, significantly higher than the 26.7–34.7% rate observed with ranibizumab monotherapy, indicating a strong anatomical advantage for combination therapy.

Why this might work

The laser treatment destroys the abnormal blood vessels by triggering a chemical reaction that clots and blocks them, while the injection stops a protein that keeps those vessels growing, so together they completely shut down and eliminate the abnormal vessels more effectively than either alone.

    When doctors treat a specific eye condition called PCV with both a laser (PDT) and eye injections (ranibizumab), the abnormal blood vessels disappear in nearly 8 out of 10 patients—much more often than with injections alone, which only work in about 1 out of 3 cases.
