Anyway, I didn't find out til we met with the nurse Friday that he'd been referred because they suspected cataracts. I didn't know 2-year-olds got caratacts, but apparently they do. Thankfully, the nurse and the doctor both ruled it out. However, they did a dilated retinal exam and we learned that Dawit is farsighted in his right eye and nearsighted in the left eye and also has an astigmatism. The nearsightedness is more severe and normally would require glasses, but the astigmatism cancels it out, so the two problems currently have little or no effect on his vision. However, the doc said he will most definitely experience vision problems in the future -- maybe in the near future -- and will need glasses. For now we will continue to watch it by having a dilated exam every six months. As he grows and his vision develops, the problems will become more obvious and start affecting his vision, then he'll get glasses.
It's an interesting balance with kids his age. If we fail to treat it promptly, it could lead to a more serious problem called amblyopia (also called lazy eye). Kids' vision fully develops by age 9 and by that time the vision system cannot be changed. So early intervention is vital. But if we introduce glasses too early, before there's a significant difference between his normal vision and glasses-corrected vision, he will likely not respect or want to wear his glasses. So for now we wait.
