Comparison of Efficacy Between 100% Platelet-rich Plasma and 100% Serum Eye Drops in Dry Eye Disease
Summary
Dry eye disease (DED) is a common eye problem, affecting 5% to 50% of the world population. Although the disease is not fatal, it substantially reduces quality of life and creates a high economic burden as high as over 50 billion from a societal perspective. Several biological tear substitutes (e.g., autologous serum (AS), autologous platelet rich plasma (APRP), and autologous platelet lysate (APL)) could effectively improve dry eyes, especially in patients with moderate to severe DED.. However, evidence on their comparative efficacy is controversial. The objective of the study is to compare the efficacy of 100% APRP with 100% AS eye drops in patients with moderate to severe DED.

Outcome
Met primary endpoint
paper The upper limit was less than the prespecified margin, indicating non-inferiority of 100% APRP vs 100% AS. PMID 39384222 ↗
paper In the short-term, 100% APRP was not inferior to 100% AS in reducing dry eye symptoms and ocular surface staining in moderate-to-severe DED. PMID 39384222 ↗
