So I'm pretty much freaking out! What is this "thing"?!?
I found this on Robbie's eye on Friday: after I tacked him up, rode him and un tacked. I noticed this completely by accident, he just happened to be looking a wierd way and I saw it. This growth/tumor/cyst/thing is on his right eye in the upper corner hidden entirely by his eyelid. I freaked out when I saw it and thought it was some bug at first haha.
So me and my trainer both looked at it and then called the vet. I hate dealing with eye and eye injuries so we weren't taking any chances. Now the vet was out about 2 weeks ago to treat Robbie's other eye (his left one) as he had a scratched cornea that needed meds and a case of conjectivitis (pink eye for horses). So he got BNP, drops and bute for his eyes and his scratched cornea is healing up well now with only a little bit of swelling left from the conjectivitis. Maybe this thing is related to the conjectivitis case? Perhaps fly eggs or something? But now I find this, I just can't win!
The vet came on Friday right after I rode him and noticed it, examined his eye and took some swabs. She was just as confused to what it was as me and my trainer were. She thought it could be a number of things: tumor, cyst, infection, etc. However, robbie's eye physically looks perfectly fine (other than the growth haha). He has no swelling, no heat, no pain, no sensitivity, nothing. He let me look at it, touch it, etc and gave no fuss. His eye is open, alert and led me to believe nothing was wrong (which is why I rode and so shocked to find it). The vet also said that his eyeball itself is unharmed (iris, pupil, etc is all fine) and the growth is on the surface and pretty superficial. So weird! She took a biposy and looked at the cells under a microscope and found that the cells looked like cells found when an allergic reaction occurs. We get even more confused then! How can he be having an allergic reaction with no heat, swelling or pain? He has also had a fly mask on since the vet's last visit 2 weeks ago so no bugs or anything could really get in there. Aghhhh so confused! We also touched on melanoma as grey horses are prone to getting skin cancer and that can be found of thier eyes. However, the cancer is found on the thirs eyelid (not the upper corner) and the growth is pink in color, not white. The vet also said that she would have seen some sign of it forming when she did the examination 2 weeks ago.
Since we were/are all so confused, the vet sent the biopsy of the growth to an equine eye specialist so he could perhaps figure out our mystery. No results yet but they should be in by tomorrow (monday). I, on the other hand, am completely freaking out! I want to know what the heck this is and I feel so incredibly horrible for my pony. I tried searching this on the internet, but had no luck. Nothing even came up remotely close. So now I turn to you guys! Have you seen/heard/read about anything like this? I really need your help, since I feel so helpless and all I can think about is Robbie not having an eye in the end of all this. :(
