2 yr old Terrier - Molly - has what appears to be long, thread-like worms in eyes and eyelid. She paws at her ears and eyes a lot. Also she has what appears to be focal seizures while sleeping which have become increasingly more frequent. I rescued her from a rundown trailer park at a very young age. I am especially concerned because I have two older dogs with some of the same symptoms.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! I can't really see in your pictures clearly-I know it is very hard to get our pets to sit still sometimes. What you are describing sounds like Thelazia. As many as 100 worms can actually be present in the tear ducts, etc. it has been reported in humans as well so please be careful and wash your hands frequently and thoroughly. The condition is caused by hatches fly larva. You'll have to take her in to your vet for treatment-likely they will prescribe an antiparasiticide like ivermectin or moxidextin, and she may require antibacterial drops for the eyes as well. I hope this helps and Molly feels better soon!
