Currently, I have a pterygium in both eyes and just started treatment using the Castor Oil treatment. What I do is dip a Q-tip into the bottle of castor oil and put 1-2 drops directly onto the pterygium. I don't know if it's just in my head or not (since I am so eager to get rid of them), but I am already starting to notice the castor oil going to work. In one eye, the pterygium is beginning to fade a bit. I will keep you updated on the prognosis. Good luck! :)
