An ophthalmologist examining the eyes of a patient explains to the nurse that the patient has an irregular curvature or uneven contour of the eye, resulting in impaired light refraction that causes blurred vision at all distances
Which condition does the nurse inform the parents about?
A.
Astigmatism
B.
Hyperopia
C.
Myopia
D.
Strabismus
ANS: A
In myopia, light rays do not reach the retina, causing blurred vision at a far range and clear vision at a close range. In hyperopia, vision is unclear at a close range and is clearer at a far range. Strabismus, or crossed-eye appearance, results in misalignment of the eyes. Astigmatism may be present at birth or acquired. Light rays are unevenly distributed in the eyes, causing blurred vision at all distances. This condition is associated with birth hyperopia and myopia.
