Microbiota association in patients related to uveitis.

Disease	Number of patients	Region	Results	Reference
Behçet's disease	22*	Italy	Altered gut microbiota composition, reduction of butylate production	(40)
Behçet's disease	12 (5 had uveitis)	Japan	Altered gut microbiota composition, increased fecal secretory IgA	(41)
Behçet's disease	32	China	Altered gut microbiota composition, transplantation of fecal microbiota from patients exacerbated EAU	(44)
Autoimmune uveitis	13 (10 idiopathic, 3 VKH)	India	Altered gut microbiota composition	(42)
Acute anterior uveitis	38	China	No significant change in gut microbiota composition, altered fecal metabolic phenotype	(43)

^*Presence of uveitis or eye inflammation was not mentioned.
