Please tell me if the passage has any grammatical errors:
Diabetic retinopathy (DR) is the most common and detrimental 
microvascular complications of diabetes mellitus. It has become one of the top causes 
of blindness and visual impairment in the working age population. However, the 
prevention and treatment options for DR are limited, invasive, expensive and most are 
focused on the advanced stages. The gut microbiota is an intricate system that alters the 
body's microenvironment and its dysbiosis associated with DR strongly. Recently, more 
and more investigation on the relationship between microbiota and DR enhance our 
understanding toward how gut microbiota influence the occurrence, development, 
prevention and treatment of DR. In this review, we summarize the changes in gut 
microbiota in animals and patients with DR, the function of metabolites and anti diabetes drugs. NAME_1, we discuss the potential ability of gut microbiota as an 
early diagnostic marker and targeting for DR, both in the healthy people or in diabetic 
patients. Finally, the microbiota-gut-retina axis is presented to help us understanding 
the mechanisms underlying the effect of gut microbiota on trigger or promoting of DR, 
with the focus on key pathways such as bacterial dysbiosis and gut barrier dysfunction, 
which promote inflammation, insulin resistance, retinal cell and acellular capillary 
damage that finally lead to DR. Hence, we can hope to achieve a non-invasive and 
cheap treatment of DR by modulating the gut microbi Your entire response should be in English, and in all capital letters.
