Glad to hear she is all better. Given the fact this resolved immediately after a shed does anyone else speculate this might just have been her shed bothering her eye. Maybe the ready to be shed skin had detached a bit on that eye/eye area and it was irritating her. Or if there was a foreign irritant maybe it was dislodged when she shed. Either way... glad she's better.

Just an FYI on the saline rinse... you could also use just regular spring water to flush the eye if you have a syringe/eye dropper.Avoid flushing the nostrils accidentally in the process.
