A Trial Evaluating Intravitreal Faricimab (6.0 mg) Injections or Fluocinolone Acetonide (0.19 mg Intravitreal Implants vs Observation for Prevention of Visual Acuity Loss Due to Radiation Retinopathy

Protocol AL

This randomized controlled trial will evaluate the effect of intravitreal faricimab or fluocinolone acetonide (FAc) intravitreal implant compared with observation on long-term visual acuity following treatment of choroidal melanoma with iodine-125 plaque brachytherapy.
