Abstract
To relate costs and treatment benefits for diabetic macular edema (DME), branch retinal vein occlusion (BRVO), and central retinal vein occlusion (CRVO). A model of resource use, outcomes, and cost-effectiveness and utility. None. 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. Visual acuity (VA) saved, cost of therapy, cost per line saved, cost per line-year saved, and costs per quality-adjusted life years (QALYs). The lines saved for DME (0.26-2.02), BRVO (0.74-4.92), and CRVO (1.2-3.75) 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). Relative costs and benefits should be considered in perspective when applying and developing treatment strategies.
