CROSSED DIPLOPIA Meaning and
Definition
-
Crossed diplopia, also known as convergent strabismus, is a medical condition characterized by double vision or diplopia that occurs when looking inwards towards the nose. It occurs due to an imbalance in the alignment of the eyes, resulting in the eyes not moving together in a parallel manner. This misalignment causes the visual input from each eye to diverge, leading to the perception of two distinct images.
Crossed diplopia commonly arises as a result of a weakness or dysfunction in the extraocular muscles, which are responsible for controlling eye movements. Factors contributing to this condition include nerve damage, muscle weakness or tightness, congenital abnormalities, or certain medical conditions such as thyroid eye disease or cranial nerve palsies.
Symptoms of crossed diplopia often involve double vision experienced primarily when looking at objects up close or during periods of eye strain. The double vision may disappear when one eye is closed or when looking in certain directions. It can cause discomfort, headaches, eye strain, and difficulty focusing on nearby objects.
Treatment for crossed diplopia primarily depends on the underlying cause. Non-surgical approaches may involve the use of prism glasses to help align the eyes and alleviate the double vision. In cases where the condition is caused by muscle weakness or paralysis, certain eye exercises and vision therapy may be recommended to strengthen the affected muscles. Surgical intervention may be necessary in severe cases to reposition the eye muscles and restore proper alignment, enhancing binocular vision.

Etymology of CROSSED DIPLOPIA
The etymology of the term "crossed diplopia" can be understood by breaking down the individual words:
1. Crossed: The word "crossed" comes from the Old English word "cros", which means "a crossing" or "a mark made by two lines intersecting". It is related to the Latin word "crux", meaning "cross". In the context of "crossed diplopia", it refers to the crossing of visual axes or the misalignment of the eyes.
2. Diplopia: The word "diplopia" is derived from two Greek terms. "Diplo-" comes from the Greek word "διπλοῦς" (diplous), which translates to "double". The "-opia" suffix is derived from the Greek word "ops", meaning "eye" or "sight".
