Duckling eye problem worsening

[brooder]

Hi,
I've been posting threads for the past few weeks in regards to my now five week old white crested. She has an infection in her eye (we think from getting to close to the heat lamp as a baby) I have been rinsing it with saline and applying Terramycin to her eye, but it does not seem to be helping. I don't think she rinses it a lot as she does not seem to like to swim with her siblings (they now has a mother duck to look after them outside) I do not believe she can see out of her eye any longer, and I am incredibly concerned for her well being. She has a white, cloudy thing that has formed at the center of the eye. I don't know what else to do, and im hoping one of you can point me in the right direction. I just want what's best for her.
Thanks a lot for your help.

My duckling has the same eye problem however he was born with his eyeball not really popping out like the other
He seems loped sided and doesn’t straighten his neck all the way up like the others ....not sure if he can see from that eye
