ω-3 Intake and Visual Acuity in Patients With Retinitis Pigmentosa Receiving Vitamin A

Abstract

We conclude that mean annual rates of decline in distance and retinal visual acuities in adults with retinitis pigmentosa receiving vitamin A, 15 000 IU/d,are slower over 4 to 6 years among those consuming a diet rich in ω-3 fatty acids. To our knowledge, this is the first report that nutritional intake can modify the rate of decline of visual acuity in retinitis pigmentosa.
