In the article titled “Long-term Visual and Refractive Outcomes of ArgonLaser-treated Retinopathy of
Prematurity” published on pages 384–389, Volume 17, Issue 3 of Journal of Ophthalmic and Vision
Research,[1] Table 2 and Figure 1 were missing in the full-text PDF and HTML of the article. The online
