Amazing Eye Anatomy
What is the retina?
An eye acuity issue that is corrected with minus lenses. Also known as near sighted.
What is myopia?
A condition affecting the retina primary caused by -low birth weight, early gestational age, duration and administration of oxygen.
What is Retinopathy of Prematurity?
Total or partial lack of pigment causing abnormal optic nerve development which may or may not affect the skin colour.
What is Albinism?
The part of the eye that is absent or not fully developed and results in the condition of aniridia. It also manages the amount of light that is let into the retina.
What is the iris?
The ring-shaped coloured membrane behind the cornea of the eye, with an adjustable circular opening in the center.
What is the iris?
An eye acuity issue that is corrected with plus lenses. Also known as far sighted.
What is hyperopia?
The part of the retina that is good at seeing:
•Things that move but only in black and white
•In the dark
•Things on the sides of us (peripheral vision)
What are the rods?
Only this part of the body is affected if you have ocular albinism. If you have oculocutaneous albinism skin and hair are affected as well.
What is the eye?
The shape that is noticed in the iris of a person with the condition of coloboma?
What is a keyhole?
A nearly transparent structure suspended behind the iris of the eye whose function is to focus light rays onto the retina.
What is the lens?
Exotropia (eyes that turn out away from the nose) and esotropia (eyes that turn in towards the nose), hypertropia (eyes that turn up) and hypotropia (eyes that turn down) are forms of this.
What is strabismus?
A progressive, degenerating disorder of the light sensitive cells on the peripheral of the retina, usually genetically linked.
The place to which electrical impulses from the optic nerve should be sent, but are impeded by the condition of Optic Nerve Atrophy resulting in a range of visual challenges.
What is the brain?
Cloudy lens affecting the amount of light that can enter the eye. They can result in reduced visual acuity, blurred vision, poor colour vision, photophobia and possible nystagmus.
What are cataracts?
The nerve that carries messages from the retina to the brain.
What is the optic nerve?
Abnormal sensitivity to light.
What is photophobia?
What is Leber's Congenital Amaurosis?
This condition can affect one of both eyes, it is congenital (meaning it is present at birth), decreased acuity (from low vision to blindness) and nystagmus are present.
What is Optic Nerve Hypoplasia?
Something a person might need to wear to replace the lenses in their eyes that are no longer there because they were removed and they now have aphakia.
What are glasses?
Your eye's clear, protective outer layer. If you have "astigmatism" it is this part of the eye that is affected.
What is the cornea?
Involuntary eye movement which can be horizontal, vertical, circular or mixed and occurs with many eye conditions.
What is nystagmus?
A condition that usually begins with central vision loss, generally stabilizes at 20/200 acuity and often begins in the teenage years making it a very difficult condition socially/emotionally.
What is Stargardt's Disease?
If untreated, this condition can cause optic nerve head damage which can lead to blindness. The condition also causes increased eye pressures.
What is glaucoma?
A condition that results from injury to the brain or visual pathways in the brain rather than disorders or abnormal structures to the eye.
What is CVI?
