Disorders of refraction and accommodation (H52)
Clinical Information
Aniseikonia - A condition in which the ocular image of an object as seen by one eye differs in size and shape from that seen by the other.
Anisometropia - A condition of an inequality of refractive power of the two eyes.
Astigmatism - Unequal or irregular curvature of the CORNEA (Corneal astigmatism) and/or the EYE LENS (Lenticular astigmatism) resulting in REFRACTIVE ERROR.
Myopia - A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness.
Myopia, Degenerative - Excessive axial myopia associated with complications (especially posterior staphyloma and CHOROIDAL NEOVASCULARIZATION) that can lead to BLINDNESS.
Presbyopia - The normal decreasing elasticity of the crystalline lens that leads to loss of accommodation.
