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.
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 a problems with visual accuity.
Symptom recognition[edit | edit source]
Blurred vision is a potential symptom of Long COVID in the World Health Organization's definition.

Chronic Fatigue and Immune Dysfunction Syndrome (CFIDS) - Chronic Fatigue and Immune Dysfunction Syndrome is another term for Chronic Fatigue Syndrome, but one which emphasizes the immunological aspects of the disease. Popular in the 1990s, this term has apparently fallen into disuse.
World Health Organization (WHO) - "A specialized agency of the United Nations that is concerned with public health. It was established on 7 April 1948, and is headquartered in Geneva, Switzerland. The WHO is a member of the United Nations Development Group. Its predecessor, the Health Organization, was an agency of the League of Nations." The International Statistical Classification of Diseases and Related Health Problems (ICD) is maintained by WHO.
myalgic encephalomyelitis (M.E.) - A disease often marked by neurological symptoms, but fatigue is sometimes a symptom as well. Some diagnostic criteria distinguish it from chronic fatigue syndrome, while other diagnostic criteria consider it to be a synonym for chronic fatigue syndrome. A defining characteristic of ME is post-exertional malaise (PEM), or post-exertional neuroimmune exhaustion (PENE), which is a notable exacerbation of symptoms brought on by small exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others. An estimated 25% of those suffering from ME are housebound or bedbound. The World Health Organization (WHO) classifies ME as a neurological disease.
