I think she should be fine. My Yorkie got a very deep-looking scratch across her eye, it was about a quarter of an inch long and was white - we think she scraped her eye walking into a bush; it wasn't just a little thin line either. At that point I thought she was going blind because this scrape caused her to develop a film on her eye. It took a while to nurse it back. My vet first gave me an eye ointment to help it and asked me to come back about a week or two later for the eye drops, which contained steroids. That eye drop completely healed her. I had waited about a month to go back because the ointment seemed to heal her, but the scratch came back in the form of an aggravated red line and the eye drops (which were anti-inflammatory) made this disappear completely. My vet also did this thing where he turned off the lights, shined a flash light in her eye and let me see where the area may have been affecting her eyesight. He told me it looked to be on the surface of her eye and shouldn't really affect her eyesight. It's been about 2 - 3 years and I don't see any scars of vision impairment. The only thing I noticed, and I'm not sure if this is a result of her injury, is that she will have slightly more discharge on the eye that was injured. But other than that, it looks to have healed 100%.
