Before I left for work this morning my left eye starting acting ina strange way....flashes of light in a regular pattern, sort of an arc, in a north to south direction. What do I need to do?!! Thank you.
Dr. Rick :

Hi. I can help you this morning.

Dr. Rick :

Are you available to chat?

Dr. Rick :

I see you entered the chat room for a second.....Have you ever had anything like this before? Was it just in your left eye and how long did it last? Do you have any medical problems or take any medicine?

Dr. Rick :

Also, testing one eye at a time, does your vision seem to be affected?

Dr. Rick :

It is possible that our chat system is on the blink. I can not see anything you are typing. If this is true, we can switch to the Q&A format and continue to chat's just a little slower.

Dr. Rick :

The system says you entered the chat room again for a brief second....I'll wait a minute or two and then switch systems. With Q&A an email will post each time we talk to each other....

I have never had anything like this before. My vision is not affected. I do not take any medications. I have no medical problems.

Dr. Rick :

see you in Q&A...


Movement makes the flash more intense and noticeable. Being still makes it less noticeable.

Hi. I'm here.
Are you still here?
I'm sorry about the problem with the chat system. Let me try and answer your question.

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. Over time as it liquefies, this gel material collapses on itself and pulls away from the wall of the eye. In the process it can stimulate the retina -- causing the flashes that you 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 in 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 lightening 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 answering my question. I'll go to my optometrist as soon as he will take me. Maybe he will recommend an ophthalmologist, because I do not have one.

I am seeing big floaters now.

Your welcome. I suggest you skip the optometrist and ask around the office for the name of an ophthalmologist.....

Good luck and let me know how things turn out.
I fear that the optometrist will want to examine you and then try to give you a diagnosis and treatment plan. As a person who does a lot of retina work it is my firm belief that when it comes to this issue optometrists don't know enough to know what they don't know and are dangerous......
Thank you for the accept and positive feedback. Don't worry too much. Since your vision has not been affected even if, worse case, you have a retinal detachment in progress (which is unlikely) being examined by an ophthalmologist today should take care of things.
