Wow, 4 males in with her--she might have some severe calcium and nutritional deficiencies from being over bred if that's the case. Perhaps that is what is causing her issues. Vitamin A deficiencies in particular tend to affect the eyes.
Try to check her calcium sacks to see what her reserves look like. This can be done by gently opening her mouth (be careful in case she does have MBD as you don't want to injure her jaw). Good calcium sacks look like this: http://www.pangeareptile.com/Images/care/calsac800.jpg. If she does not have good reserves she may need a good calcium supplement.
