Brief Summary

Earlier investigations have detected low levels of macular pigment (MP) in the center of the fovea and a halo of MP at a higher eccentricity in persons with type 2 idiopathic juxtafoveal teleangiectasia (MACTEL)\[Helb H-M, Charbel Issa P, Pauleikhoff D, Scholl HPN, Holz FG, MacTel-Study Group. Macular Pigment Density and Distribution in Patients with Macular Telangiectasia. ARVO Annual Meeting 2006, Fort Lauderdale, 30.04.-5.05.2006. Program # 5701/B795\]. To date it is not known whether the total MP is reduced in MACTEL or whether even more MP accumulates at higher eccenticities compared to healthy probands. With the suggested study we aim to

  1. 1.investigate Lutein and Zeaxanthin serum levels in MACTEL probands
  2. 2.investigate and quantify MP at the posterior pole of MACTEL probands
  3. 3.detect possible changes of MP concentration and distribution following supplementation with Lutein and Zeaxanthin
