Stunted growth, also known as stunting or linear growth failure, is defined as impaired growth and development manifested by low height-for-age. [1] It is a manifestation of malnutrition (undernutrition) and can be caused by endogenous factors (such as chronic food insecurity) or exogenous factors (such as parasitic infection).
Maternal malnutrition can also factor into the poor health or death of a baby. Over 800,000 neonatal deaths have occurred because of deficient growth of the fetus in the mother's womb. [100] Deriving too much of one's diet from a single source, such as eating almost exclusively potato, maize or rice, can cause malnutrition.
The symptoms and signs associated with convergence insufficiency are related to prolonged, visually demanding, near-centered tasks. They may include, but are not limited to, diplopia (double vision), asthenopia (eye strain), transient blurred vision, difficulty sustaining near-visual function, abnormal fatigue, headache, and abnormal postural adaptation, among others.
Obscured vision due to papilledema may last only seconds, while a severely atherosclerotic carotid artery may be associated with a duration of one to ten minutes. [6] Certainly, additional symptoms may be present with the amaurosis fugax, and those findings will depend on the cause of the transient monocular vision loss. [citation needed]
The buildup of protein clumps can block normal drainage of the eye fluid called the aqueous humor and can cause, in turn, a buildup of pressure leading to glaucoma and loss of vision [3] (pseudoexfoliation glaucoma, exfoliation glaucoma). As worldwide populations become older because of shifts in demography, PEX may become a matter of greater ...
When the misalignment of the eyes is large and obvious, the strabismus is called large-angle, referring to the angle of deviation between the lines of sight of the eyes. Less severe eye turns are called small-angle strabismus. The degree of strabismus can vary based on whether the person is viewing a distant or near target.
This month, they celebrated 70 years as husband and wife. Mrs. DeHaai offered this advice: "I'm afraid some people think when they get married they're joined at the hip, you know you've got to be ...
In a left esotropia, the left eye 'squints', and in a right esotropia the right eye 'squints'. In an alternating esotropia, the patient is able to alternate fixation between their right and left eye so that at one moment the right eye fixates and the left eye turns inward, and at the next the left eye fixates and the right turns inward. This ...
