What Causes Vision Disturbances?
Vision disturbances can have various causes, ranging in severity from 'troubling' 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 vision disturbances, we could:
- Research the topic
- Find a doctor with the time
- Use a diagnostic computer system.
The process is the same, whichever method is used.
Step 1: List all Possible Causes
We begin by identifying the disease conditions which have "vision disturbances" as a symptom. Here are eight of many possibilities (more below
- Chronic Fatigue-Fibromyalgia
- Metal Toxicity
- Brain Tumor
- Diabetes II
- Mercury Toxicity
Step 2: Build a Symptom Checklist
We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
fatigue after slight exertion
slightly reduced arm function
frequent swollen cervical nodes
unexplained missed periods
severe non-specific arm pain
rapid loss of vision
long menstrual cycles
... and more than 150 others
Step 3: Rule Out or Confirm each Possible Cause
A differential diagnosis of your symptoms and risk factors finds the likely cause of vision disturbances:

Vision disturbances. Aside from any long/short-sightedness, does your vision sometimes become blurry or otherwise distorted, for example double vision?
→ No / don't know
→ Occasionally / moderately
→ Often / severely
Based on your response to this question, which may indicate either vision disturbances or severe vision disturbances, The Analyst™
will consider possibilities such as:
|Double vision, especially if it is associated with headache, is a significant symptom of a brain tumor.|Diabetes Type II
|High blood sugar can cause two problems which affect vision, namely blurred vision and retinopathy – a disease of the back of the eye. Blurred vision is one of the first signs of elevated blood sugar. The shape and size of the lens in your eye changes when your blood sugar fluctuates. This swelling of the lens can cause blurred vision. |
If you notice blurred vision, you should have your blood sugar checked. The acceptable range for fasting glucose is 80-110mg. If your blood sugar is substantially higher or lower than the acceptable range, contact your doctor. When your blood sugar is controlled, your vision will return to its previous state.

|In the early stages, central vision may be blurred or distorted, with things looking an unusual size or shape. This may happen quickly or develop over several months.|
