Resolved Question:

I have for the last 4 days had a worm like black line with two black spots at the end of the line in my left eye. (It is almost like the ones you have just prior to a headache sets in but I have no headache). What can cause this as it is making my sight a bit blurry while my right eye is 100%.

Dr. Rick :

Hi. I'm online and happy to answer your question today.

Dr. Rick :

You are likely experiencing a PVD or posterior vitreous detachment, a common event that happens in many people.

You have a thick gel material in the middle of your eyes called the vitreous. Over time as it liquefies, this gel material collapses on itself, forms little clumps that you can see as dots, lines or bugs. As these clumps form the vitreous pulls away from the wall of the eye. In the process it can stimulate the retina -- causing the flashes that you may see.

It is recommended that you see your ophthalmologist to look at the retina to make sure there are no problems such as a retinal hole or tear. In most cases, there are no problems, but this exam is precautionary and allows for preventative treatment of any lesions that are found.

If you notice a sudden increase in floaters, flashes of light (like a lightning storm), or a shadow/veil in the periphery of your vision, this can be worrisome for a retinal detachment. You would need to contact your ophthalmologist promptly in that case.

Thank you for the precise expalantion. Does the retina disappear by itself? How long can it linger on in the eye?
Expert:  Dr. Rick replied 5 years ago.
This does not involve the retina but rather the "jelly" inside the back of your eye, called the vitreous.

What can you do about the floaters? Well, floaters don't go away, and they don't really get worse. Over time they tend to "sink" out of your central vision and you brain "filters" them out so you don't notice them so much anymore. They almost never cause significant visual problems except, of course, if they cause a secondary retinal detachment as discussed above. The only way to decrease or remove the floaters is with a major surgery called a vitrectomy. As a retinal specialist for almost 2 decades I've only done this procedure to remove floaters in a handful of cases.
