It would be good to start a new thread of your own as Wyorp Rock suggested. A crusted shut eye may be MG. Is there any swelling of an eyelid or the face? You can buy saline eye wash (Bausch and Lomb has Eye Relief Eye Wash) and then when dry, Apply a small dab of either Terramycin eye ointment from the feed store, or a dab of Neosporin ointment into the eye twice a day. If it is caused by MG, you may want to treat with Tylosin powder in the water for 5 days.No other symptoms, I’ve used a variety of drops, but it continues to return. I have not treated that frequently though.
