Core Tip

Core Tip: Autologous serum eye drops (ASEDs) are safe and effective alternative therapies for managing moderate-to-severe dry eye syndrome (DES). The study comparing ASEDs to conventional artificial tears found that ASEDs significantly improved the ocular surface disease index score, tear break-up time, Schirmer I test, corneal fluorescein staining, and conjunctival impression cytology over 12 wk. The ASEDs group showed greater improvement in these measures than the artificial tears group. Moreover, no severe adverse events were reported, indicating the safety of the ASEDs. These findings suggest that ASEDs are a valuable treatment option for patients with DES who respond poorly to traditional therapies.
