Next-Generation Sequencing of the Ocular Surface Microbiome: In Health, Contact Lens Wear, Diabetes, Trachoma, and Dry Eye

Conclusions: There is a significant likelihood that there is at least a transitory ocular surface microbiome, with Acinetobacter, Corynebacterium, Propionibacterium, Staphylococcus, and Streptococcus detected in at least 7 of 11 studies. However, further investigation attempting to control for environmental and methodological contaminants (Aquabacterium and Bradyrhizobium are commonly identified as contaminants in DNA extraction kits) is required. Bacteria, such as Propionibacterium, Staphylococcus, and Streptococcus, capable of causing sight-threatening infections may reside on a healthy ocular surface. With greater understanding, we can establish whether elements of the ocular surface microbiome are harmful or protective (despite their small quantities); furthermore, new therapeutic agents can be identified to treat and prevent ocular surface infection and inflammation.
