Loss of vision can have various causes, ranging in severity from 'serious' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose loss of vision, we could:
|Multiple Sclerosis||1%||Ruled out|
|Brain Tumor||0%||Ruled out|
Has your vision become worse within the past few years? In other words, do you have greater difficulty seeing with one or both eyes, especially when the lights are dim?
Possible responses:→ Don't know
→ No, my vision has remained about the same
→ Yes, it is slightly worse now (slow decline)
→ Yes, it is a lot worse now (rapid decline)
→ Yes, I have (almost) completely lost my sight
Vision loss is a possible consequence of aspartame consumption.
Loss of vision in one or both eyes could indicate a brain tumor.
