AS THEN′OPY

Syn. As the no′pia , L. In pathology , incapacity to keep the eyes fixed on near or small objects for any length of time without confusion of vision. The common causes are over-exertion of the eyes, particularly by artificial light, or by a very brilliant one, or during convalescence; congestion of the ocular ve els; debilitating discharges or indulgences; and general nervous debility, however produced. It “appears to consist in weakne of the apparatus by which the eye is adjusted for the vision of near objects;” and along with this “there is an irritable state of the retina, connected in some manner with a tendency to internal congestion of the eyes.” [97] The treatment may consist of rest to the eyes, and ablution of them in cold water, with such other efforts to restore their tone and the general health as are noticed under Amaurosis . The prospect of complete cure, when the cause is not removable, is unfavorable; but even when confirmed the disease is not likely to end in blindne . The use of convex spectacles of very low power will generally be found serviceable. See Eye , Spectacles , Vision , . [97] T. W. Jones, ‘Defects of Sight,’ Lond., 1856; p. 82.
