Republican Rep. Dan Crenshaw of Texas announced Saturday that he will be sidelined for a few weeks due to an operation to preserve what is left of the combat veteran’s sight.

“A few days ago, I noticed some dark, blurry spots in my vision, which seemed out of the ordinary,” Crenshaw, a former Navy SEAL, said in a statement shared on Twitter. “I went to get this checked out by an ophthalmologist on Thursday and they discovered that my retina was detaching.”

“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,” he wrote.

Crenshaw said that the damage from the explosion that cost him the sight of one eye left the other badly damaged.

“The blast from 2012 caused a cataract, extensive tissue damage, and extensive damage to my retina. It was always a possibility that the effects of the damage to my retina would resurface, and it appears that is exactly what has happened,” he wrote.

“The prognosis I received on Thursday is obviously very bad,” he wrote, noting that his wife, Tara Crenshaw, drove him to Houston on Friday where he underwent emergency surgery at the Michael E. DeBakey VA Medical Center.

He noted that his wife “was by [his] side the entire time.” Crenshaw does, however, face a long recovery.

“The surgery went well, but I will be effectively blind for about a month,” he wrote.

“I want to especially thank the phenomenal team of doctors and nurses at the VA who took such good care of me. During the surgery they put a gas bubble in my eye, which acts as a bandage for my retina. This means I have to be face-down for the next week or so, unable to see anything.”

Crenshaw said he will update his constituents on his condition but otherwise lay low.

“This is why you’re not going to hear from me for a while. I likely will not be conducting interviews and likely will not be posting on social media, except to give updates on my health and recovery.”

Crenshaw put a bold face on his prognosis.

“I have gotten through worse before, and I will get through this,” he wrote. “I’ve got Tara by my side, and we are here in Houston with plenty of support.”
