Have Trauma On Back Of Eye And Berlin's Edema Causing Swelling. How Long It Takes To Get Cured?
It is understandable to be concerned.
Berlin's edema is also called commotio retinae, it is an area of whitening in the retina caused by blunt trauma. Though the name has the word edema, there is no actual edema or bleeding. It is due to disruption of the photoreceptors and retinal pigment epithelial damage. The changes resolve spontaneously.
The retinal pigment epithelial part of the eye has alot of different functions including the absorption of light, defends the retina against free radicals and transport of various substances.
The photoreceptors are nerve cells found in the retina, there are two types and damage to one of these types can lead to decrease in night vision which you are experiencing.
In most cases normal vision returns after 1 to 3 months.
The fact that you have been seen at least twice and various investigations have been normal is reassuring.
It may take up to and beyond a month but your vision will return.
I hope this helps, feel free to ask any other questions
Many Thanks

You are not being a nuisance, it is natural to be concerned about your vision.
The flashes that you are experiencing are part of the disturbance of the retina and should resolve as well.
