Natural Dry Eye Treatment: Autologous Serum Tears

When over-the-counter drops and prescription medications have not provided enough relief, autologous serum tears offer a biologically natural alternative for managing persistent dry eye disease. According to the American Academy of Ophthalmology, autologous serum tears are recommended for patients with severe dry eye who have not responded adequately to conventional therapies (AAO, 2024). These custom eye drops are made from your own blood and contain growth factors, vitamins, and proteins that closely mirror the composition of healthy tears. At Greenwich Ophthalmology Associates, our dry eye specialists in the greater NY/CT region evaluate patients with moderate to severe dry eye to determine whether autologous serum tears may be an effective addition to their treatment plan. When left unmanaged, dry eye disease can lead to progressive changes on the ocular surface, including corneal staining and reduced visual quality, which is why early and consistent treatment is important for preserving both comfort and long-term eye health.

Autologous serum tears are prescription eye drops created from a patient's own blood serum. The word autologous means derived from the same individual. Your blood serum, the clear liquid that remains after red blood cells and clotting factors are removed, shares many biochemical similarities with natural tears. It contains essential nutrients that nourish the corneal surface and promote cellular repair in ways that synthetic tears cannot replicate. Patients who wear contact lenses may notice that dry eye symptoms are more pronounced during lens wear, and optimizing the ocular surface before and during contact lens use can make a meaningful difference in wearing comfort and lens tolerance.

Autologous serum tears are typically reserved for patients with moderate to severe dry eye who have not achieved adequate relief from other treatments. This includes patients with Sjogren syndrome and other autoimmune conditions, those with persistent corneal epithelial defects, and patients with graft-versus-host disease affecting the eyes. We use LipiView diagnostic imaging to evaluate the thickness of the lipid layer of the tear film and assess the structural health of the meibomian glands, providing objective data that guides treatment decisions. Keeping an open dialogue with your eye care provider about how your symptoms change over time helps ensure that your treatment plan stays effective and responsive to your needs.

Some patients benefit from autologous serum tears after refractive surgery or other procedures that temporarily compromise the ocular surface. The growth factors in serum can support healing during recovery. Because the tear film plays a central role in protecting the cornea and maintaining clear vision, any disruption in tear quality or quantity can have a noticeable impact on daily visual function, especially during tasks that require prolonged focus. Our team is available to answer additional questions and help you understand all of your options during a consultation at our Stamford office.

Patients with reduced corneal sensation may benefit from the nerve growth factors present in autologous serum. This condition can result from viral infections, surgery, or other causes that damage corneal nerves. Prescription anti-inflammatory eye drops may be recommended for patients with moderate to severe dry eye disease, as these medications target the underlying inflammation on the ocular surface that contributes to the cycle of dryness and discomfort. Regular monitoring of your ocular surface health allows us to adjust your treatment as needed and address any new concerns that may arise over time.
