Learn more about natural treament of dry eyes.
A 2008 study shows that using eyedrops with Vitamin A Palmitate can improve symptoms of blurred vision and tear film after just 4 weeks of usage. It was a prospective, randomized, controlled, parallel group study whose purpose was to compare the efficacy of vitamin A (retinyl palmitate) and cyclosporine A 0.05% eye drops in treating patients with dry eye disease.
In 3 identical clinical trials, 150 patients with dry eye disease were treated either 2x daily with cyclosporine A 0.05%, or 4x daily with retinyl palmitate 0.05%, or neither. In addition, preservative-free artificial tears were given 4x daily in every group. Corneal dye staining observation, Schirmer tear tests, tear film break-up times, dry eye symptom scores, and impression cytologic analysis results were obtained before treatment and at the first, second, and third months after treatment began.
Both vitamin A eye drops and topical cyclosporine A 0.05% treatments led to significant improvement in blurred vision, tear film break-up times, Schirmer I score results, and impression cytologic findings in patients with dry eye syndrome (P < .05) compared to the control group treated with preservative-free artificial tears alone.
Both vitamin A eye drops and topical cyclosporine A 0.05% treatments are effective for the treatment of dry eye disorder.
