Brief Summary:
Exudative age-related macular degeneration (ARMD) is complicated by choroidal neovascularization (CNV). Although anti-vascular endothelial growth factor treatment is the gold standard treatment, recurrence is the main limitation of the treatment. The changes of the CNV vascular structure is expected to provide information regarding recurrence. In the eyes that the vascular structure is clearly seen in indocyanine green angiography (ICGA), the vascular changes after ranibizumab injections will be investigated prospectively.

Condition or disease Intervention/treatment Phase
Exudative Age-related Macular Degeneration Drug: ranibizumab Phase 4

Detailed Description:
For patients having exudative ARMD with CNV, whose vascular structures are clearly demonstrated in ICGA , ranibizumab is injected monthly three times, then pro re nata to 6 months. Vascular structures of CNV is investigated at baseline, 3 and 6 months using ICGA. Expected number of patients are 48 eyes from 4 centers, competitively.

Drug Information available for: Ranibizumab

Arm Intervention/treatment
Experimental: ranibizumab
0.5mg of ranibizumab is injected into the vitreous cavity monthly 3 times for the 3 months then pro-re-nata (PRN) for following 3 months.
Drug: ranibizumab
0.5mg of ranibizumab is injected into the vitreous cavity through pars plana.
Other Name: intravitreal injection of ranibizumab (Lucentis, Novartis)

Primary Outcome Measures :
  1. Caliber of Choroidal New Vessel (CNV) [ Time Frame: 6 months ]
    Caliber of the largest CNV is measured using a software of IVAN (developed by Wisconsin University) that measures a caliber of retinal vessels using a semi-automatic method. An indocyanine green angiography (ICGA) image showing the vascular structures of CNV was processed to invert black and white for the analysis. The image was loaded in the software, and the course of the arteriolar CNV was indicated manually. Then average thickness of the vascular segment was calculated.

Secondary Outcome Measures :
  1. Lesion Size of CNV [ Time Frame: 6 months ]
    Lesion size of CNV is measured in fluorescein angiography using software, and find correlation with caliber of choroidal new vessels.

  2. Visual Acuity in ETDRS Letters [ Time Frame: 6 months ]
    Visual acuity was assessed using the ETDRS chart. The ETDRS chart includes 100 letters as the maximum possible score, and 0 letters read as the minimum possible score. Higher scores represents better functioning.

  3. Visual Acuity Changes [ Time Frame: baseline and 6 months ]

    Visual acuity is measured at baseline and 6 months using ETDRS chart. The changes was calculated by visual acuity at 6 months minus visual acuity at baseline.

    Positive values represent improvement of visual acuity, and negative values represent worsening of visual acuity at 6 months compared to baseline.
