What the study is testing
OBJECTIVES: I. Examine the concentration of docosahexanoic acid (DHA) and other n-3 fatty acids in plasma, erythrocyte, and adipose tissue in patients with various forms of retinitis pigmentosa and Usher syndrome.
II. Determine the synthesis and catabolism of DHA from linolenic acid in these patients.
III. Determine the synthesis, absorption, and catabolism of DHA under different dietary conditions in these patients.
