(Redirected from Double vision)

A wide range of ocular signs and symptoms occur in ME/CFS. These include eye pain, photophobia (light sensitivity), visual processing problems, floaters and spots, tearing, dry eyes, poor focus, double vision, scotomata, blurred vision, tunnel vision, night blindness, depth-of-field loss, nystagmus, and early cataracts.[1]

Prevalence[edit | edit source]

  • 2001, In a Belgian study, 74.4% of patients meeting the Fukuda criteria and 77.2% of patients meeting the Holmes criteria, in a cohort of 2073 CFS patients, reported problems with visual accuity.[2]

Symptom recognition[edit | edit source]

Blurred vision is a potential symptom of Long COVID in the World Health Organization's definition.[3]

Brian Vastag was able to prove with qEEG and cognitive tests he had "significant problems with visual perception and analysis, scanning speed, attention, visual motor coordination, motor and mental speed, memory, and verbal fluency" winning his long term disability (LTD) claim.[16]
