This video shows a cornea with Fuch’s dystrophy. You can see guttata or guttae on the back surface of the cornea. These bumps indicate endothelial pump difficulty, and appear as a “beaten metal” appearance. If you look closely (look where the arrow is pointing) you can see a pock-marked surface that looks like craters on the moon.
Guttae are an important finding to note prior to cataract surgery, as this indicates a lower endothelial cell count and could lead to a decompensating cornea afer cataract extraction.

Good video. Theses guttata were very large and easy to see. It would be interesting to see a corresponding specular photomicrograph for comparative analysis.

Yes, that would be interesting. Unfortunately, I don’t have access to a specular machine. Never really found them very useful, as I primarily look at corneal thickness (when determining risk for endothelial decompensation before cataract surgery).
I have catarct surgery coming up and I do have corneal guttata. I now am afraid to get the cataract done because of this guttata. Can you advise me what I should do. thank you
