Vision, eyes.. and other stuff

In the begging of class we reviewed the last blog post (as usual)

and then started with a quiz that was based on the sheet we were given last class. (the human eye)

Next we also reviewed over our Animal vision booklets we had received the previous class.

Then we began all of the presentations on Eye Defects, where everyone was given a topic to research on eye defects and make a presentation about.

We learned a lot in the presentations:

Amblyopia (lazy eyes): the lack of

perfect vision.

usually blur vision in the effected eye. one eye or even both eyes wander to different spots and blur the vision. most patients don't notice the difference in vision but some people notice the eyes wondering to different

things in the room.

Treatments: patching the good eye or instilling tropical atropine in the eye for better vision.

Cataracts: A clouding that develops

in the lens of the eye. this can be caused by aging, ultra violet light, diseases (such as: diabetes) and others.

Treatments:

eye surgeries ECCE and ICCE

wearing sunglasses

and more

Myopia: near sightedness,

where the eyeball is longer that it normally should be which effects

the way light enters the eye.

can be caused hereditary.

Treatment:

corrective lenses

laser eye surgery

Colour Blindness:

inability to distinguish betweencertain colours, is

more common in men because it is effected by the X gene if it is damaged which would be more common in males. can be hereditary.

Treatments:

contact lenses

Astigmatism:

when the cornea is abnormally curved and you cannot see properly. common in people who are near sighted.

Treatments:

To end class Mr.B suggested another assignment involving presentations
