Comparing Efficacy of Autologous Serum Eye Drops With and Without Insulin in Autoimmune Dry Eye: A Randomized Clinical Trial

Introduction: Dry Eye Disease (DED) of autoimmune origin is often severe and resistant to conventional treatments, necessitating alternative therapeutic options. Autologous Serum Eye Drops (ASED) have gained recognition for their biochemical and biomechanical properties, which closely mimic those of human tears. These properties make ASED an effective treatment for DED. Furthermore, topical insulin has demonstrated anti-inflammatory effects and promotes epithelial cell proliferation, differentiation, and migration, all of which contribute to maintaining ocular surface stability. As a result, insulin may serve as a valuable adjunct in treating moderate to severe autoimmune DED. Purpose: This study aims to assess and compare the effectiveness of autologous serum eye drops (group 1) and autologous serum eye drops combined with insulin (group 2) in improving the clinical signs and symptoms of moderate to severe DED in patients with autoimmune diseases, particularly those with Sjögren's Syndrome.
