Cobwebs in the eyes

12/15/2000

Question:

If one has cobwebs in the eyes, is that associated with a detachment or a vitreous hemorrhage? What`s the difference between the detachment and a hemorrhage and how does one know which one they have had? Are large cobwebs caused by a hemorrhage? Also, are large cobwebs considered common floaters or are they more serious than just dots or circles?

Answer:

An eye doctor would need to dilate a patient`s pupils to determine if the reported cobwebs were caused by a problem in the vitreous, the retina, or both. If patients report floaters, cobwebs, or a loss of vision, it is impossible for them to precisely determine what part of their eye is causing the problem. Blood in the vitreous can last a long time, but it usually gravitates downward into the lower portion of the vitreous - and out of the way of central vision - after several weeks.

If you have cobwebs in your vision, you should see an eye doctor as soon as possible to get a definitive diagnosis and treatment plan.
