I would keep trying to get all of the solid gunk out of the eye socket. To me it looks like the eye may be gone. Rinse with saline or an eye wash such as Bausch and Lomb Eye Relief twice a day. Tylosin and doxycycline both treat bacteria that can cause respiratory disease, such as MG. Tylosin is usually given for 3-5 days. Since she has had it for 9, I would try to get some probiotics into her. She could have a secondary infection in her eye. Since we are not vets it is hard to know what kind. You might check with your vet about giving any more drugs.
