Hi. I'm online and happy to answer your question today.
You do not have to worry that you were experiencing anything serious, such as an angle closure glaucoma attack.
It is more likely that you were having an anterior segment/tear film problem. Also, it is not unusual for there to be a "after image" after the light is turned out.....once again, nothing to panic about.
Let me tell you a little bit about tear film problems such as allergies, dry eye and blepharitis. While I don't believe that this is the complete cause of your episode, it could have contributed to it and, since the treatment is very easy and can be done at home, it won't hurt to learn about this.....
When it comes to allergies it is almost impossible to pin down the offending agent(s) and, therefore, treatment needs to focus on controlling the symptoms. Dry eyes are very common and can be improved by a stepwise series of therapies. First, the use of natural tears 4-6+ times/day to augment your natural tear production, if this doesn’t work then you can try temporary punctal occlusion of the lower puncta, then, if needed, temporary occlusion of all 4 puncta then, if indicated, surgical ( non-reversible) closure of the puncta. The openings to your tear drainage system are called puncta and you have one opening on each lid, near your nose.
Blepharitis is a condition where glands in the eyelids are not functioning normally. They become plugged and instead of putting out their normal clear, oily secretions, they put out thick, toothpaste like gunk. You may not be able to see this “gunk” yourself, unless it is really bad, but it shows up clearly on slit lamp examination.
The best treatment for this condition daily lid scrubs combined with warm compresses. I like to use baby shampoo for lid scrubs. In the shower, place the shampoo on your index fingers, close your eyes, raise your eyebrows (to stretch the skin on your eyelids) and scrub back and forth along your eyelashes for 3 to 5 minutes. The hot water in the shower helps to soften the plugged oils in the glands while the mechanical scrubbing with your soapy fingers removes the oils.
Baby shampoo lid scrubs will also help to wash away allergens and stimulate tear production, thereby addressing all three of your issues. Remember, this is not an instant fix. While you are waiting for the lid scrubs to have affect you can use over the counter allergy pills such as Travist, dimetapp or Zyrtec.
Should your symptoms get worse, your vision become significantly affected or things just not get better in 3 weeks or so you should have a complete eye examination by your local ophthalmologist to look for other, less common, causes of your symptoms.
So, in addition to the above "extra" information, what is the take home message?
First. Don't worry.
Second. Try the above treatment and see if you can improve your tear film
Third. Have a complete eye exam by an ophthalmologist in the near future (not an emergency) just to make sure everything is OK with your eyes and....
Fourth. Don't worry :)
