As said, it's the MS, not the EMS.
What Sasuke and Madara have is the EMS.
But what would be the point of reanimating an eyeless Uchiha? There are a number of reasons as to why Itachi would have his eyes.
1. For plot reasons. Itachi is stopping the Edo Tensei, which would obviously mean a battle would ensue. It is somewhat likely that Kishimoto brought him back with his eyes for this reason.
2. It was stated that you had the abilities you had in life. This would mean that Itachi has his eyes as technically, he died with his eyes still intact. Sasuke did not receive Itachi's eyes until a little while after his death. I find this the most likely.
3. The user of Edo Tensei has some leeway in the way you are brought back. Meaning that if Kabuto wants Itachi back in a healthy manner, then it would be like that.
4. Kabuto is also a medical ninja. If he was able to experiment on Madara, then it isn't a stretch to say that he could also bring back sight to Itachi.
