Are possible retinal detachment it's the weekend what steps should you take until you can see a doctor?
Immediately contact a retinal specialist. Look in the phone book for your area, or call your optometrist or opthamologist or regular doctor. Retinal specialists have "after hours" answering services who will contact them with your name, number and symptoms. The "on call" opthamologist will call you back and set up a time, either within a few hours or the next day, for you to come in for a thorough retina exam. Because the retina peels like wallpaper, it's very diffidcult to reattach it. There is no glue...but, there are at least 3 other possible routes to get it reattached and anchored. if it peels up to and over the macula, or center of the eye, possible loss of central vision will occur once the retina is reattached. So! Time is precious if you want the least amount of vision loss and the least invasive reattachment procedure. Read all you can about retina detachment on the internet. Good luck!
Why is full recovery of strength not possible with a reattached arm that was cutt off?
Because it's currently not possible to perfectly reattach every nerve.
When is vitrectomy performed for retinal detachment?
Vitrectomy is typically performed in more complex cases of retinal detachment. During the procedure, the vitreous gel is removed, and the retina is reattached with the help of gas or silicone oil.
Why is it important for your eye to contain a lens?
Without the lens in your eye you can not form a image on the retina. As the retina is kept at a fixed distance you change the thickness of the lens to get the image on the retina.
What is the iPad's retina display?
Retina stands for the fact that the retina display has actually more pixels than our human eye (retina) is possible to see. It delivers stunning picture quality, and is far more crisper than a full HD TV.
Photosensitive receptor cells of the retina make the perception of color possible?
cones
How does refraction allow you to see?
The refraction of light by the cornea and lens of the eye makes it possible for an image to form on the retina. Without the formation of an image, it would be possible for the retina to detect the presence or absence of light, but not shapes or objects.
What is retinal detachment?
Retinal detachment is when the retina, the part of the back of the eye which contains numerous blood vesses, because detached from the wall of the eyeball. It can be serious and can lead to blindness if left untreated. It is most commonly caused by high blood pressure. The high blood pressure causes pockets to form between the retina and the other lays of tissues in the eye. Over time, the suction between the wall of the eye and retina is gone and the retina slowly detaches from the eye. It is not usually noticed until the retina is actually detaching from the eye. During this time you may see blurriness, floaters or blindness. Fortunatly, the retina can be surgically reattached to the eye and vision can be restored if treated as soon as possible.
What is the layer of photoreceptors?
the retina contains the rods and cones which sense the amount of light and different colors respectively.
