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.

Yes, leaking kidneys, or kidney conditions that cause proteinuria (excess protein in urine), can affect the eyes. This is due to the accumulation of proteins in the bloodstream, which can lead to complications such as retinal damage and changes in vision. Conditions like diabetic nephropathy and hypertension, often associated with kidney issues, can also contribute to eye problems, including diabetic retinopathy or hypertensive retinopathy. Regular monitoring of kidney health is important for maintaining overall health, including eye health.

What part of the eye is responsible for most of the refraction of incoming lights?

The cornea is responsible for most of the refraction of incoming light in the eye. It has a curved shape that helps bend light rays as they enter, focusing them onto the retina. While the lens also contributes to refraction, particularly for fine-tuning focus, the cornea accounts for approximately 70-75% of the eye's total refractive power.

How long for vision to be cloudy after retinal cryopexy?

After retinal cryopexy, it is common for vision to be temporarily cloudy or blurred, which can occur within a few hours post-procedure.
