Within the past 20 minutes a blind spot is developing on the right side of my vision for both eyes and It looks like zig zag patterns with oscillating light. Kind of like when you push on your eyes when they are closed and you see the lights but this is with my eyes open and with no touching at all. It's slowly getting bigger and is starting to noticeably affect my vision.
Hi. I'm Dr. Rick and I have two decades of ophthalmology experience. I'm online and happy to answer your question today.

What you are describing is consistent with ocular migraines, a condition that I not only treat in my office but that I have been dealing with personally for decades.
A typical migraine headache starts with shimmering lights, often times they surround a blurry area or have dots or jaggedly lines associated with them. They tend to progressively increase in intensity and sometimes march across the visual field causing difficulty with reading. Many times this is then accompanied by nausea, irritability, sensitivity to bright lights and/or loud noises. After the onset of the lights (called scintillating scotomas), the headache typically starts and the light show tends to progressively go away.
Many people can have this migraine phenomenon WITHOUT the headache; it is called an acephalgic migraine. Some people even start having these late in life, or may have had a few much earlier in life that behaved differently and haven't had any for decades and then begin to have them; this is not uncommon. A family history of migraines is often present as well.
This is nothing to worry about. It is not a sign of a more serious underlying condition, brain tumor or anything like that. If the episodes become so frequent that they are bothersome there are medicines that can be used to decrease their frequency or stop an episode once it has started.
I, personally, have been suffering from this condition for almost 30 years. I almost never got the headaches after the visual effects.
There was one time, I was in the middle of a very delicate retina operation, when an attack started. After a few moments I lost most of my central vision and the inferior part of my visual field. I, calmly, removed my surgical instruments from the patients eye and we all sat around in the OR for 15 minutes until my vision returned. Other than that my ocular migraines have not really caused me any significant problems :o)

Does this make sense to you?

Thank you very much, that explains it perfectly after I looked up more of the conditions. It seems to have subsided but it was the first time it's happened and it got me quite worried. Thanks Dr. Rick.

The first time it happened to me I totally freaked the time I got to the "quack shack" ( I was a Freshman in College) it was gone.

The nurse explained what was going on to me...but, back then, I had to spend 4 hours in the library with the card catalog and the stacks to get more information.

Times sure have changed, eh?

Don't forget to mash the positive feedback button for me...the one labeled "excellent" is the most fun to push by far ;)

It's safe for you to press the positive feedback button now if you so desire. And, never fear, even after you press that button I don't go up in a puff of smoke -- I'll still be right here to continue helping you, but, as I do work for tips, I want to make sure you are happy before rating me.

Have a good weekend
