Worth (medical term)

Worth (pronounced: /wɜːrθ/) is a term used in various medical contexts. Its etymology is derived from the Old English word 'weorþ', meaning 'value' or 'importance'.

Definition

In a medical context, Worth can refer to a few different concepts:

• Worth 4 Dot Test: A test used in Optometry and Ophthalmology to assess a person's color vision and binocular vision.
• Worth's Syndrome: A rare genetic disorder characterized by epidermolysis bullosa, dwarfism, and mental retardation.

Worth 4 Dot Test

The Worth 4 Dot Test is a clinical test generally used by Optometrists and Ophthalmologists to detect abnormalities in a person's binocular (two-eyed) vision and color perception. The test involves the use of four colored dots (two red, one green, and one white) and corresponding colored glasses (one red lens and one green lens).

Worth's Syndrome

Worth's Syndrome is a rare genetic disorder. It is characterized by the presence of epidermolysis bullosa, a condition that causes the skin to be very fragile and to blister easily; dwarfism, which is short stature that results from a genetic or medical condition; and mental retardation, a condition diagnosed before age 18 that includes below-average general intellectual function and a lack of skills necessary for daily living.
