I will do my best to assist you in answering your question.
In regards XXXXX XXXXX changes you have noticed in regards XXXXX XXXXX visual field, it maybe best to followup with your neuroopthalmologist so he canevaluate you for any changes that may have occurred since august
As far as the flashes of light ,these could be ocular migraines or due to a floater tugging on the retina which produce the flashes you are mentioning
An ocular migaine is a vasospasm of the vasculature of the eye that will produce flashes of light.These are usually benign and can be triggerred by caffeine or stress among some of the causing factors.
The floater is something you would want to have your opthalmologist dilate your eyes for so he can make sure that the floater is not tugging on the retina so much that it is causing a tear.
Should you see an increase in the number of flashes of light or floaters, wavy distorted vision, or a curtain like effect, you would want to be seen immediately by your opthalmologist.
In summary in your case ,it would be best to have your opthalmologist evaluate you with a repeat visual field test and to dilate your eyes to determine if a floater is tbe cause for the flashes of light you are seeing
