Medically Unexplained Vision Loss: A Self-Reported Analysis

Summary of symptoms (from most to least distressing)
– Permanent bilateral stationary blind patches in vision
– Episodes of skin numbness lasting for up to 21 days
– Light-headedness; ranging from mild to collapse
– Generalised anxiety and OCD symptoms

Symptom Checker

I thought I would list all of my symptoms during an episode (in no particular order as this would over-complicate things) so that anyone experiencing similar issues, whether diagnosed or not, can compare to their own symptoms. I am interested to hear from anyone with similar symptoms! My first episode occurred towards the end of 2010 and lasted a few weeks and the second lasted several months (neither were treated). Some recent dizziness and numbness suggests a third episode may now be occurring. 

– Headaches, often triggered by sitting in certain positions such as slouching

– Dizziness

– Some sensation loss in the skin on certain parts of the body, never complete numbness

– Slight weakness and loss of coordination

– Loss of visual field in both eyes (this symptom did not resolve after each episode, unlike other symptoms)

– Feeling of pain or pressure behind the eyes, sometimes a sharp stabbing pain in the eye
