Abstract

Purpose of Review

In this article, we define the ocular surface microbiome (OSM) and review the literature investigating its putative role in anterior segment diseases.

Recent Findings

The complex networks of microorganisms that compose the OSM play integral roles in many physiologic processes. The three most common bacterial phyla that contribute to the microbiome are Proteobacteria, Firmicutes, and Actinobacteria, although the composition has been found to vary by anatomic site, age, and systemic disease. Multiple ocular conditions have definitive associations with OSM alterations, some with specific signature colonization of atypical genera or species, while others have more broad changes in abundance or alpha diversity of natural microbiota.

Summary

Dysbiosis of the OSM appears to play a role in multiple ocular surface and anterior segment diseases. Future larger, longitudinal, and multicentered studies investigating its composition will lend insight into the pathophysiology of disease and potential methods for therapeutic interventions.

Invest Ophthalmol Vis Sci. 2016;57(13):5116–26. https://doi.org/10.1167/iovs.16-19803. Conjunctival swabs from over 100 healthy volunteers were analyzed by culture, 16S sequencing and biome representational in silico karyotyping, along with swabs from facial skin, buccal mucosa and controls from the environment. The authors found a paucibacterial, distinct conjunctival bacterial community when compared with the facial skin, buccal mucosa and controls.

Sci Rep. 2017;7(1):9880. https://doi.org/10.1038/s41598-017-10494-9. The study identified the composion of the resident ocular surface micrbiome in a healthy population at baseline and then at 1 month and 3 months to asses for change over time. They found that the ocular surface microbiome overall has low diveristy and does not appear to have a core composition, although the microbiome appears specific to an individual.
