Sounds like your vet was just explaining it in a way you can understand easily. I am a nurse so my vet will use medical "jargon" and know I will understand...I sometimes forget that others might need it explained simply.
The excess skin and too much gland will most likely be caused by and partly the over stretched ligament
so yes it makes sense because to me it reads the same just different terminology xx
picture a balloon filled with water tied to an elastic/rubber band...stretch the band and let go..the balloon will bounce back into place. The more its stretched the less bouncy it is.
now picture the same balloon tied to a piece of stretchy string...not as bouncy as the elastic....stretch it and the balloon will pull on the string more and not bounce back to where it was. That's how a Cherry Eye works...the more it pops and stretches the gland/ligament/3rd lid/skin the less likely it is to go back to normal so eventually the only cure is removal. But if caught before its over stretched and tacked back it can be successful and stay back xx
