Hi. I'm Dr. Rick and I have two decades of ophthalmology experience. I'm online and happy to answer your question today.
First of all this is not normal.
Nor is it related to your laser treatment.
That being said, this is a very, very worrisome symptom you are having. Please allow me to explain:
It sounds like what you are suffering from is something called Amaurosis fugax
Amaurosis fugax is the transient loss of vision in one eye. It has many causes and, in the early 1990's, a study called the Amaurosis Fugax Study Group defined and grouped them to help with diagnosis and treatment of this problem.
What can cause AF? It can be due to an embolism, problems with the blood, problems with the eye itself or, sometimes due to no cause we can figure out (idiopathic). I would be happy to go through all the different diagnostic possibilities in each of these categories but I don't think that is the best use of your time.....you need to know what to do.
AF is a symptom that something serious is wrong. It can be a warning that you are heading toward a dangerous vascular event such as a TIA, stroke or even death. It is important for you to see your ophthalmologist
and possibly your internal medicine physician ASAP. What will they do? A complete history and physical, a complete eye examination, maybe a fluorescein angiogram
of your retina, laboratory tests, possibly ultrasound
of your carotid arteries
or an CT/MRI of your head.
Treatment depends on what is found on the above workup.
I can not stress enough the need for you to be seen for a complete exam as soon as possible.
Does this make sense to you?
