To understand floaters, first you need to appreciate the anatomy of the eye:
Eye floaters are small specks, strands or clouds that move across your vision. They can drift across your field of vision. They are often more obvious when you look at something bright.
Eye floaters usually don’t affect your vision. If they are large, they may seem to make a shadow over your vision. This can happen in some types of light.
Eye floaters become more common as we age. They don’t normally go away, but they don’t usually need treatment. Over time, your brain adapts to seeing the floaters. When this happens you don’t notice them as much.
Eye floaters can seem like:
1.black or grey dots
2.blobs
3.squiggly lines, strands or ‘worms’
4.cobwebs
5.rings
They may dart away when you look at them. Sometimes they seem to drift away from your field of vision.
Eye floaters are tiny strands of collagen inside the vitreous. When these stands clump together, they make a shadow over the retina. The eye floater is actually the shadow that you can see.
In rare cases, eye floaters can be caused by a rip in the eye. They can also happen because of a bleed in the eye.
A detached retina happens when your retina separates from your eyeball. It is more common if you:
1.have had a trauma to the eye
2.are short sighted
3.have had cataract surgery
4.have had a detached retina before
See your doctor or optometrist if floaters in your eye are affecting your vision.
You should visit your emergency department if:
1.floaters appear suddenly
2.you have many more eye floaters than usual
3.you also have flashes of light in the same eye
4.there is darkness to the side or sides of your vision
Your doctor will ask you about your symptoms. They will also examine your eyes to work out what is causing the eye floaters.
Your doctor will rule out other possible causes of eye floaters such as inflammation or infection.
They may refer you to an ophthalmologist(specialist eye doctor). The ophthalmologist can look more closely at the back of your eye.
If your eye floaters are bothering you, there are 2 types of treatment:
1.surgery to remove the floater (vitrectomy)
2.laser treatment (vitreolysis)

TowardPi OCT無論哪一個model 都可以把傳統2D影像通過獨有的算法呈現出3D圖像，今天起可以通過3D立體影像觀察視網膜每一幀的細微變化，當中存在於玻璃體間的飛蚊更可以以立體方式呈現於病人眼前。醫生可以通過影像更加具體講解給病人知，讓整個治療過程更加透明。那麽拍攝玻璃體當中飛蚊需要有什麼技巧？答案是完全沒有，只需要執行一般拍攝OCT便可以，大概1秒。想試試？
