Anorexia, macular degeneration link found

A Greek study compared 13 female patients suffering from anorexia without visual failure with 20 healthy age- and sex- matched controls. 

The patients with anorexia showed a decreased macular and retinal nerve fibre layer thickness, as well as a decrease in the electrical activity of the macula. 

Retinal thickness of the macula was higher in women with “restrictive-type” anorexia (meaning those who habitually reduce daily caloric intake) compared to binge-purge patients, suggesting the latter had greater anatomical impairment of the fovea, the researchers said in an article in the British Journal of Ophthalmology. 

Visual impairment due to anorexia could be caused by decreased appetitive function, possibly resulting from impaired dopaminergic neurotransmission as a result of food transmission or related to the underlying pathophysiology of anorexia nervosa, they said .
