Dry Eye Disease Clinical Trial
Official title:
Comparison of Treatment Efficacy Between 100% Platelet-rich Plasma and 100% Serum Eye Drops in Moderate to Severe Dry Eye Disease: A Randomized Controlled Trial Protocol
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.
The study is a single-center, double-blinded randomized, parallel, non-inferiority trial. Patients will be recruited from out-patient clinic, Department of Ophthalmology, Ramathibodi Hospital, Bangkok and will be randomized to receive either 100% APRP or 100% AS eye drops (1:1 ratio) for 4 weeks. The primary outcomes include ocular surface disease index (OSDI) and ocular surface staining evaluated using the Oxford scale. Secondary outcomes are fluorescein break-up time (FBUT), Schirmer's I test (ST I), meibomian gland parameters and adverse events. ;
