Vitamin A palmitate eye gel, sodium hyaluronate eye drop improves dry eye in patients with thyroid eye disease

Posted on

Amongst patients with thyroid eye disease (TED) experiencing dry eye syndrome, use of a vitamin A palmitate gel was found to improve tear film stability and a sodium hyaluronate eye drop resulted in improvements in discomfort, according to a study.

Patients in this study had inactive mild or moderate-to-severe TED with dry eye syndrome and were randomly divided to receive vitamin A palmitate eye gel 3 times/day for 1 month or sodium hyaluronate eye drops.

A total of 80 patients started the trial, of which 64 completed treatment. At baseline, there were no significant differences between the groups.

In eyes treated with the gel there was a significant improvement in break-up time and corneal fluorescence staining grade (effective rate = 91.2%) and in eyes treated with the drops, there was significant improvement in ocular surface disease index score and corneal fluorescence staining grade (effective rate = 67.7%). Break-up time was also significantly longer in the group treated with gel than in the group treated with drops.
