Scoto- is a prefix used in scientific terminology to denote darkness or absence of light.

The prefix skoto- comes from the Greek word "skotos", which means "darkness". It is often used in medical and biological terms to describe various conditions associated with the absence or insufficiency of light.

Some examples of using the prefix skoto-:

1. Scotopia is night vision in which the eye is sensitive to low light.

2. Scotoma is a blind spot in the field of vision.

3. Scotophobia is the fear of the dark.

4. The scotocycle is a circadian rhythm associated with activity at night.

5. Scotoderma is a skin condition with increased sensitivity to sunlight.

Thus, the prefix scoto- is widely used in scientific terminology to denote various phenomena and conditions associated with the absence or insufficiency of light.

**Scoto- (Scoto-)** is the first part of compound words, meaning “darkness,” used in the names of diseases associated with certain types of animals, certain animal organs. The name of diseases is usually combined with the word "cancer", for example: Scotonian cancer. Here are some examples of words with this prefix:

**1. Scotoma is a white spot on a dark background.** Scotoma is an area of ​​defects in central vision and is visible as small dark spots or light dots in the field of vision or a concentric ring-shaped area of ​​it. This spot can be located anywhere on the visual line. For example, a scotoma may be located under the retina, behind it, or along the path to the optic nerve, but not along the entire visual cortex of the brain. In most cases, scotoma is accompanied by decreased visual acuity. Sometimes a scotoma results in a limited field of vision. Understanding the fact that a scotoma is present is one of the most significant tasks for the ophthalmologist. Knowing about its existence, the doctor always conducts research to determine the cause of the disease. Since only eliminating the scotoma itself does not guarantee complete restoration of visual functions.

**2. Soniconus crasis is a strong tremor of the limbs.** This is excessive, sweeping swaying of the limbs (usually limbs) that occurs with an artificial (violent) rhythm of movement. Refers to choreic hyperkinesis. Normally, rhythmic movements occur when performing smooth movements with the arms or legs (for example, when a person dances). Such movements are clear and well coordinated. At the same time, obsessive rhythmic oscillatory movements (trochaic) - often accompanied by jerky, uncoordinated, uncertain or trembling movements - may indicate a pathology of the nervous system. Movement disorders often indicate the presence of a psychological or physical illness that progresses due to improper functioning of the brain.

3.** Sonopsis (sonospasmoplegia) syndrome of mental asthenia / Weakness that occurs when the eyes are closed, blindfolded, like apepsia, i.e. lack of perception of visual images or perception of visible light
