Anna Nicole Smith’s former lover Larry Birkhead has revealed that his and the late glamor model’s daughter, Dannielynn suffers from “strabismus, which is a turning in of one of her eyes.

He told ET: “I’ve been taking her to the doctors and … [mom] Anna [Nicole Smith] had taken Dannielynn to the doctor [in the Bahamas] to see about it when she was just a few months old.”

The former photographer, 34, says the child now wears an eye patch to help treat the condition, which is prevalent in about 5 percent of children and cannot be outgrown.

“At first she was really open to it and it didn’t really bother her,” he says. “Now, she’s gotten a little smart because she can pull it off, so it’s a little bit harder for me to patch her.”

The youngster – whose name Dannielynn is a tribute to Smith’s deceased son Daniel, takes a course of medicated eye drops.

But if neither works, he says she may have to have surgery.

“I’m going to do everything to make sure that it’s corrected,” he said. “But having lost Anna and [her son] Daniel and my dad — my dad just came out of a simple surgery and he died — it’s just tough for me to think about surgeries with [Dannielynn].”

Birkhead says he is not sure how his daughter developed the eye condition.

“All of the opinions that I had [from doctors], every one of them said that it’s very, very unlikely, because no one knows one-hundred percent what causes [strabismus],” says Larry.

“But I point-blank ask every single doctor, ‘Could any medications that Anna was on have caused this?’ and they said that it’s more likely that a genetic reason could have caused it.”
