Brief Summary:
Because a possible synergism of radiation and inhibitors of vascular endothelial growth factor has been shown in cancer patients and patients with wet macular degeneration, this pilot study is being conducted to determine whether treating wet macular degeneration with a combination of Lucentis and proton beam irradiation is safe. Lucentis is an inhibitor of vascular endothelial growth factor which was recently FDA approved for treatment of wet macular degeneration. It appears to be the most effective therapy thus far for wet macular degeneration among all drugs FDA approved for this condition. If no major safety issues are associated with this combination therapy, a larger study will be conducted to determine whether this combination therapy is more effective than Lucentis monotherapy.

Condition or disease Intervention/treatment Phase
Age-related Macular Degeneration Drug: Proton beam irradiation and ranibizumab Early Phase 1

Detailed Description:
Five subjects diagnosed with wet macular degeneration will be treated with standard of care, i.e. intravitreal Lucentis injection monthly for the first four months and as needed thereafter. Within six weeks of the first Lucentis injection, the eye will also be treated with 24 Gy of proton beam divided into two fractions. Each subject will be followed for 2 yrs with monthly examination.

Drug Information available for: Ranibizumab

Arm Intervention/treatment
Experimental: proton beam with ranibizumab
Intervention is 24Gy proton radiation in 2 fractions given within 6 weeks of first dose of intravitreal ranibizumab (0.5mg) drug combined with four monthly doses of intravitreal lucentis and monthly prn lucentis thereafter.
Drug: Proton beam irradiation and ranibizumab
ranibizumab 0.5mg intravitreal monthly x 4, then prn combined with low dose proton beam irradiation 24Gy (2 fractions, 24 hours apart) during the first month of study.
Other Name: Lucentis and proton beam

Primary Outcome Measures :
  1. Incidence and Severity of Ocular Adverse Events [ Time Frame: 24 months ]
    Any ocular adverse event identified by eye examination during the study follow-up will be recorded and determined for possible or probable relation to study treatment.

Secondary Outcome Measures :
  1. 1. Change in BCVA From Baseline [ Time Frame: 24 months ]
    change in number of letter read correctly in study eye compared to the number of letters read correctly at baseline, i.e. BCVA (number of letters read correctly) at 24 months minus BCVA (number of letters read correctly) at baseline
