Print this article Texas Rep. Dan Crenshaw will be “effectively blind” for about a month after undergoing emergency surgery to reattach the retina in his left eye, he said Saturday. The Republican congressman and U.S. Navy SEAL veteran detailed the prognosis and surgery that will leave him "pretty much off the grid" until he recovers. “A few days ago, I noticed some dark, blurry spots in my vision, which seemed out of the ordinary," Crenshaw said. “I went to get this checked out by an ophthalmologist on Thursday and they discovered that my retina was detaching.” He continued, “This is a terrifying prognosis for someone with one eye, and the nature of the injuries that I sustained in Afghanistan. Anyone who knows the history of my injuries knows that I don’t have a ‘good eye,’ but half a good eye.”
