These pics sure look like the advanced stage of Pink Eye to me, as it already has the red VOLCANO looking protrusion showing. The next sep is where it ruptures and the eye will essentially collapse and be dry and dead.
At this point, you will most likely end up with a white and for the most part -- blind eye, but not always entirely.
I have had great success in the earlier stages of the problem by injecting pen into the socket above the eye ball, but in the later stages, it does not work as well.
Now I use a 1-2 ml squirt of Nuflor -- no needle, just squirted on the eye and massages around. I absolutley DO know this is ""Extra Lable"" so keep that in mind, but it does work and within a few days the redness is gone and the swelling as well. These advnced stages though tend to be less effective no matter what you use. An eye patch as most have said will keep the sun from further hurting the tissues and keep her from squinting as well, leave em on for a week or more, they make a difference over time.
The real key to these things is EARLY reccognition and treatment. The sooner the better, often times with no long term affects. This one may be pretty far along to tell what will happen.
Best of luck -- Terry
