  Purpose

Study the effectiveness of the treatment detachment of retinal pigment epithelium secondary to polypoidal choroidal vasculopathy. Efficacy will be assessed by regression of polyp area after twelve months, compared to baseline. Treatment under study is a triple therapy with: 1) reduced-fluence photodynamic therapy (PDT), 2) intravitreal (IVT) triamcinolone and, 3) IVT ranibizumab, for the treatment of detachment of the retinal pigment epithelium (PED) secondary to Polypoidal Choroidal Vasculopathy (PCV).

Primary Outcome Measures:
  • Auxiliary Exams - Optical Coherency Tomography (OCT) [ Time Frame: 12 months after first procedure ] [ Designated as safety issue: Yes ]

    Optical Coherency Tomography (OCT): To Assess the Retinal Thickness using the ETDRS thickness profile and to evaluate the regression of the pigment epithelium detachment.

    The Auxiliary exams are done at the Baseline, 10 days after the procedure and every 30 days until the end of the study.


  • Auxiliary Exams - Indocyanine green angiography (ICGA) [ Time Frame: 12 months after first procedure ] [ Designated as safety issue: Yes ]

    Indocyanine green angiography (ICGA): To Evaluate the polyp lesions regression

    The Auxiliary exams are done at the Baseline, 10 days after the procedure and every 30 days until the end of the study.


  • Auxiliary Exams - Fluorescein Angiography (FA) [ Time Frame: 12 months after first procedure ] [ Designated as safety issue: Yes ]

    Fluorescein Angiography (FA): To Evaluate subretinal neovascularization

    The Auxiliary exams are done at the Baseline, 10 days after the procedure and every 30 days until the end of the study.

Arms Assigned Interventions
Triple Therapy

The treatment (single group) will be treated with reduced-fluence Photodynamic Therapy (Visudyne -Verteporfin infused over 10 minutes at a dose of 6mg/m2 and following by activating light [wavelength of 689 nm] applied 15 minutes after the start of infusion with a light dose of either 25 J/cm2 for 83 seconds), followed by an Intra-vitreous triamcinolone (4mg/0.1ml) on the same day.

After 10 days, patients will be subjected to an injection of Intra-vitreous ranibizumab (0.5 mg/0.05 ml). After this first injection, Intra-vitreous ranibizumab will be repeated twice, on a monthly basis, for a total of three injections

Criteria

Inclusion Criteria:

  • Patients with PCV associated with PED near the polypoidal lesion recently diagnosed, documented by FA, ICGA and OCT.
  • Visual acuity between 20/40 and 20/400.

Exclusion Criteria:

  • Blepharitis or external eye infection.
  • Allergy to ranibizumab, verteporfin, triamcinolone, fluorescein or indocyanine green.
  • Patients unable to provide informed consent.
  • Concomitant ocular disease that impairs visual acuity.
