Preferred Label : astigmatism;

MeSH definition : Unequal curvature of the refractive surfaces of the eye. Thus a point source of light cannot be brought to a point focus on the retina but is spread over a more or less diffuse area. This results from the radius of curvature in one plane being longer or shorter than the radius at right angles to it. (Dorland, 27th ed); Unequal or irregular curvature of the CORNEA (Corneal astigmatism) and/or the EYE LENS (Lenticular astigmatism) resulting in REFRACTIVE ERROR.;

MeSH hyponym : Astigmatism, Oblique; Oblique Astigmatisms; Astigmatism, Mixed; Mixed Astigmatisms; Astigmatism, Myopic; Myopic Astigmatisms; Astigmatism, Hyperopic; Hyperopic Astigmatisms; Astigmatism, Corneal; Astigmatism, Lenticular;
