Uveite

Uveitis is an inflammation of the uvea, a membrane between the cornea and the sclera. It can manifest with redness of the eyes, pain, photophobia, excessive lacrimation and vision of black dots. Among the triggers, coeliac disease and other autoimmune diseases can be found, so that in some cases there is a regression of inflammation due to the gluten-free diet, prescribed after diagnosing coeliac disease. 

Sjögren syndrome
Sjögren’s syndrome is an autoimmune disease that affects almost exclusively women (90% of cases), especially around the age of 50 and presents itself as a strong eye dryness. The exocrine glands are affected, in particular the ocular ones causing redness, burning and a less clear vision.
Scientific research on this syndrome would have identified an improvement in symptoms thanks to the gluten-free diet.

Uveitis and Sjögren’s syndrome are not the only symptoms of coeliac disease that do not directly affect the gastrointestinal tract. These include, for example, loss of tooth enamel, fertility problems in women, poor growth in children. These disorders are frequent in cases of untreated celiac disease, perhaps because not yet diagnosed
