Hi. I'm online and happy to answer your question today.
It sounds like you may be having a problem with an area of your retina called the Macula. This part of your eye is very important for all your daily activities such as reading, watching TV, driving etc.
The other thing that this could be is called a vitreous floaters. Here is some info on this, benign, condition:
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.
If the black spot you are experiencing DOES NOT fit the above description you should see an ophthalmologist (eye MD) ASAP for a complete eye exam. If your macula is having problems, such as macular degeneration, swelling, diabetic changes, etc, then the sooner it is treated the better.
If your spot DOES fit the above description, there is no emergency but, as I discussed, you should see an ophthalmologist in the near future just to make sure everything is OK.
Does this make sense to you?
