Purpose To relate costs and treatment benefits for diabetic macular edema (DME), branch retinal vein occlusion (BRVO), and central retinal vein occlusion (CRVO). Design A model of resource use, outcomes, and cost-effectiveness and utility. Participants None. Methods Results from published clinical trials (index studies) of laser, intravitreal corticosteroids, intravitreal anti-vascular endothelial growth factor (VEGF) agents, and vitrectomy trials were used to ascertain visual benefit and clinical protocols. Calculations followed from the costs of 1 year of treatment for each treatment modality and the visual benefits as ascertained. Main Outcome Measures Visual acuity (VA) saved, cost of therapy, cost per line saved, cost per line-year saved, and costs per quality-adjusted life years (QALYs). Results The lines saved for DME (0.262.02), BRVO (0.744.92), and CRVO (1.23.75) yielded calculations of costs/line of saved VA for DME ($1329$11,609), BRVO ($494$13,039), and CRVO ($704$7611); costs/line-year for DME ($60$561), BRVO ($25$754), and CRVO ($45$473); and costs/QALY ($824 to $25,566). Conclusions Relative costs and benefits should be considered in perspective when applying and developing treatment strategies.
