Our turtle has white eye disease, and his eyes can't be opened at all. What other useful methods can I apply erythromycin to his eyelids?

as soon as I answered the same question, I copied it for you here, and I wrote it myself!

I can give you my advice. First, use chloramphenicol eye drops (which are available everywhere) to drop turtles' eyes, even if they are closed. Drop more drops from top to bottom, so that the eye drops can fully flow into the eyes, and then dry them for 2 hours before entering the water. Because of the dirty eyes, it is best to use cold boiled water for water. Drop the eyes three times a day, and dry them for 6 hours a day. (Dry for 2 hours after each drop, and then enter the water! Instead of a 6-hour dry cultivation)

Chloramphenicol is used to protect turtle shell and meat, and chloramphenicol eye drops are the best for eye drops, which are available in hospitals there! Don't ask questions!
