Optic nerve

The potential bandwidth of fiber has not been fully utilized and it is already transmitting signals at multiple gigabits per second. Fiber optic cables can go an average of 62 miles versus 1.2 miles that copper can go before the signal needs to be regenerated or boosted. Overall, it is apparent that fiber optics is a more cost effective solution. Fiber optics is non-metallic and is not susceptible to interference, such as electromagnetic interference (EMI), radio frequency (RF) or lightning.…

Overview Optic neuritis is the term used when there is inflammation in the optic nerve, which is the bunch of nerve fibers tasked with transmitting visual information to the brain. A rare condition, it is most commonly associated with multiple sclerosis in that it can possibly be an early indication of the disorder. It is also often related to neuromyelitis optica, which is a condition similar to MS in that it causes an inflammation of the spinal cord and optic nerve. It is not yet known what…

Glaucoma is a disease that causes blindness in the eye and it also damages the optic nerve, which is what helps the eye keep its good vision. The optic nerve comes from the sensory fibers and it is what conducts impulses from the retina to the brain. Elderly people are more likely to develop glaucoma when they’re around the age 60 but glaucoma can also develop on young adults, or an infant could just be born with it. 1 out of 10,000 babies are born with glaucoma, which may not seem like a many,…

a recovery they spread joy and hope. Two diseases that are similar and yet so dissimilar are Transverse myelitis and Optic neuritis. Both diseases are neurological and known to be connected to MS (multiple sclerosis). MS is a disease in which the nerves of your brain and spinal cord are inflamed and damaged. Optic neuritis is the inflammation of the optic nerve, which is the nerve that connects what a person to sees to their brain. Transverse myelitis is inflammation that can cause severe…

that the entire mechanism can function as a whole. Visual prosthetics fall under two different categories. The first category includes prosthetics that are implanted in the eye. These usually require less invasive surgery for installation than optic nerve implants because surgery involves only the eye and does not require tampering with the skull around the eye (Pezaris et al, 2009). Research on in-eye prosthetics mainly focuses on developing a retinal prosthetic. A positive aspect to developing…

vision loss within a day if is not treated as an emergency. Secondary glaucoma: type of glaucoma resulting from injury or other eye disease Normal tension glaucoma: that type of glaucoma arises even though the pressure in the eye is normal but the optic nerve is damaged Congenital glaucoma: mostly manifested in children.Most often they were born with a defect in the angle of drainage. Signs and symptoms Glaucoma affected the peripheral vision first.Consequently, it is accompanied by a set of…

Glaucoma - The Silent Thief of Sight To understand well the subject, we must first appreciate how the eyes enables us to see, and the major role of the optic nerve plays in this process. Let us compare our eyes with a camera. When taking pictures, as we click on the shutter, the lens of the camera let the lights go inside then focuses the light on the film and when the light hits the film, an image was created. This idea is same with a normal eye. When light rays enter the eye through the pupil…

Primary Congenital Glaucoma Overview- Glaucoma is a disease of the optic nerve. The optic nerve receives nerve impulses from the retina and transmits them to the brain, where it recognizes these electrical signals as vision. Glaucoma is characterized by a particular model of progressive damage to the optic nerve, which usually begins with a subtle loss of side vision (peripheral vision). If glaucoma is not diagnosed and treated, it can progress to blindness. Glaucoma is usually, but not always,…

transparent tunnel that traces its path through the vitreous body of the eye, spanning the optic nerve disc to the lens. In an adult person, the hyaloid canal carries lymph to help change the volume of the lens. When the lens expands, the hyaloid canal compresses, so that the eye’s internal pressure and volume remain constant (Merriam-Webster). Optic nerve: A part of the central nervous system, the optic nerve connects the eye to the brain, carrying electrical signals formed by the retina to…
