As I recall the data books said that Izuna died in battle, but Tobi had said that Izuna gave Madara his own eyes, which had to be done before he died in battle.

This infers that Izuna went into battle after giving up his eyes, in other words he went into battle while being blind and then died in battle.

The answer is that Izuna did not(exactly) die in battle and the Data book was full of BS.
