QUADRANTANOPSIAS Meaning and
Definition
-
Quadrantanopsias refer to a type of visual field defect or loss of vision characterized by the absence of perception in one quarter or quadrant of the visual field. More specifically, it is an acquired condition that affects one or both eyes, resulting in the inability to see objects in the affected region. These visual field defects often occur due to damage or dysfunction in the visual pathway, particularly in the brain's occipital lobe or optic radiations.
Individuals with quadrantanopsias typically experience a loss of vision in either the upper or lower quadrant, or in the left or right quadrant of their visual field. This means that they may have difficulty perceiving objects or images on one side, while the other side remains unaffected. The severity of the condition can vary, ranging from a slight reduction in vision to complete blindness in the affected quadrant.
Quadrantanopsias can have various causes, including stroke, head trauma, tumors, or certain neurological disorders. Treatment options for quadrantanopsia are limited and primarily focus on visual rehabilitation to help maximize the use of the remaining intact visual field. These may involve strategies such as scanning techniques, compensatory head and eye movements, and the use of optical aids to enhance visual function.
Overall, quadrantanopsias are a specific type of visual field defect resulting in the loss of vision in one quadrant of the visual field, which can be caused by damage or dysfunction in the visual system.

Etymology of QUADRANTANOPSIAS
The word "quadrantanopsias" is derived from three components: "quadrant", "an", and "opsias".
1. "Quadrant" comes from the Latin word "quadrans", meaning "a quarter". It is used to describe one of the four equal parts into which a two-dimensional plane can be divided.
2. "An" is a prefix commonly used in medical terminology, derived from the Greek word "an", meaning "not" or "without". It is used to negate or indicate the absence of something.
3. "Opsias" is a medical term that comes from the Greek word "opsis", meaning "sight" or "vision".
Therefore, "quadrantanopsias" is a plural noun formed by combining elements that signify "without" or "lack of" vision in a specific quarter of the visual field.
