Deep Dive Into Raptor Ophthalmology
This past summer, one of our Instagram videos went viral—a clip of a Great Horned Owl receiving eye drops during treatment. The video sparked a wave of curiosity, with many people asking, “Do birds really get eye drops?” The answer is yes! In fact, eye drops are a common and effective treatment for many of the patients in our clinic.
Unfortunately, one of the leading reasons raptors are admitted to our care is due to vehicle or window collisions, which often result in brain injuries and eye trauma. During physical exams, we use an ophthalmoscope to carefully evaluate both the exterior and interior of the eye for any injuries that may require treatment or even surgery. Eye injuries can vary greatly, and we use a variety of medicated eye drops to treat them. One of the most versatile and fascinating treatments we use is serum eye drops.
So, what is serum? Serum is the clear, liquid portion of blood after it has been stripped of red blood cells, clotting factors, and certain proteins. This nutrient-rich fluid is packed with anti-inflammatory properties and enzymes that promote epithelial healing—the process by which cells repair damaged tissue and form a protective barrier. While the body naturally initiates this healing process, serum eye drops provide an extra boost to speed recovery.
How do we make serum eye drops? It’s a simple yet incredible process:
- We collect a small amount of blood from the patient.
- The blood is allowed to clot in a tube and then spun in a centrifuge.
- The centrifuge separates the red blood cells and clotting factors, leaving behind a clear, golden liquid—serum.
- The serum is diluted with sterile saline, placed in a dropper, and applied to the patient’s eyes.
The results we’ve seen are truly remarkable. Serum eye drops can make a life-changing difference for injured raptors, helping them heal faster and more effectively. It’s incredibly rewarding to witness the transformation—from crafting the serum to seeing our patients regain their vision and return to the wild where they belong.
