I am so sorry! Is the yen still alive? I would call your veterinarian to see if you can bring her in. Here are people who can help. @azygous , @EggSighted4Life , @SacredWaves , @Eggcessive , @Wyorp Rock , @SilverBirds . I think that is all. Reach out to them. Hope she is doing okay.
How was she injured or attacked by something? Can you open the eye to see if it is intact or punctured? You can apply plain Neosporin ointment to any wounds. Terramycin eye ointment or plain Neosporin Ointment can be applied into the eye for injuries.
