It still looks like in the eyelid to me. If it were an infection or cold it can move into the sinuses, right in front of eye in back of nostril. Yes you can use neosporin in the eye, even though it says not too. If their is no nasal discharge it still could be something in her eye. Does her eye have bubbles? If so that could be respiratory, and then I would dose her with Tylan. Hope you see improvement soon.
