Eyes

The eyes are organs. They detect light, regulate the light through a diaphragm, focuses it through adjustable lenses and converts them into electo-chemical impulses in our neurons by photoreceptor cells called rods and cones. The image is converted into a set of electrical signals that are transmitted to the brain via neural pathways that connect the eye to the optic nerve and visual cortex of the brain. In short, eyes are very complex optical systems that convert light to distinguish objects and movement around us.

Why pupils are not constricted in central pontine myelinolysis?

In central pontine myelinolysis, the primary issue is the demyelination of axons in the pons, which affects the brain's ability to process and relay signals properly. Pupils remain non-constricted because the condition primarily disrupts the pathways involved in voluntary motor control and does not directly affect the autonomic pathways that control pupil size. The pupils typically respond to light and accommodation through intact midbrain reflexes, which remain functional despite the demyelinating process. Thus, central pontine myelinolysis does not lead to the pupillary constriction often seen in other neurological conditions.

What causes an opaque grey floater in the eye?

An opaque grey floater in the eye is often caused by changes in the vitreous gel, which is the clear substance filling the eye. As we age, the vitreous can become more liquid and shrink, leading to the formation of clumps or strands that cast shadows on the retina, resulting in floaters. In some cases, these floaters can indicate more serious conditions, such as retinal tears or detachments, so it's important to consult an eye care professional if they appear suddenly or are accompanied by other visual disturbances.

Why does light blind us?

Light can blind us primarily due to its intensity overwhelming the photoreceptors in our eyes, leading to temporary visual impairment. Bright light, especially from sources like the sun or camera flashes, can cause the pupils to constrict quickly, but if the light is too intense, it can result in discomfort or even damage to the retina. Additionally, rapid changes in light levels can disrupt our visual processing, making it difficult to see clearly. This phenomenon is often referred to as "dazzle" or "glare."
