Retinitis Pigmentosa Research

  1. Patients with retinitis pigmentosa appear to have faulty cellular uptake of the amino acid Taurine. Disturbed utilisation of vitamin A also appears to play a part in retinitis pigmentosa, and a subgroup of patients benefit from supplementation of this vitamin. Head KA, Altern Med Rev 1999 Oct;4(5):342-59
  2. The essential fatty acids alpha-Linolenic acid and DHA may be required for those with retinitis pigmentosa to support normal functional development of the retina. Uauy R, et al. Lipids 1996 Mar;31 Suppl:S167-76
  3. A diet high in polyunsaturated fats (e.g. corn oil), and low in vitamin E, selenium, sulphurcontaining amino acids (e.g. Taurine, methionine), and chromium were related to a build up of pigment that mimics one type of retinitis pigmentosa. Katz, et al. Invest Ophthalmol Vis Sci 1978
  4. Lutein supplementation in high doses improved both visual acuities and visual fields after 2-4 weeks of treatment in 16 subjects, and was especially effective in blue-eyed individuals. Dagnelie G., et al Optometry 2000 Mar;71(3):147-64
