opthamology
A cystoscope is an instrument that allows visual examination of the bladder. Cystoscopy is the name of the process.
There are 4 visual pigments held in cone cells of the eye.
Retinoscopy or ophthalmoscopy is the process of examining the retina of the eye to examine the blood vessels and other structures.
If the right eye does not receive light during early development, it can lead to a condition known as amblyopia or "lazy eye," where the brain fails to process visual information from that eye effectively. This lack of stimulation can result in reduced visual acuity and can affect the development of neural pathways associated with vision. Additionally, the brain may prioritize information from the unaffected eye, leading to imbalances in visual perception and depth perception. Early intervention is often crucial to mitigate these effects and promote proper visual development.
A person who tests people's eyes is called an optometrist. An optometrist is a type of doctor who practices optometry, which is the examining of eyes for inconsistencies such as visual defects and prescribing corrective glasses or contact lenses for those with imperfect sight.
visual
The eye's visual receptors reside within the retina. The eye's visual receptors consist of four different types of receptors including rods, blue cones, red cones and green cones.
The optic nerve is responsible for transmitting visual information from the eye to the visual cortex in the brain. It carries signals in the form of electrical impulses that are generated by the retina in response to light stimulation.
The optic nerve carries visual information from the eye to the brain, allowing us to see and process what we observe in our environment.
An autoscope is either of two medical instruments, one for examining one's own eye, the other for examining one's own larynx and trachea.
It is called Gastroscopy
The second cranial nerve is called the optic nerve. It carries visual information from the retina at the back of the eye to the visual centers in the brain, allowing us to process and interpret visual stimuli.
