Ocular surface microbiota alterations in patients with pterygium.

ABSTRACT:

Purpose

To examine the alterations in the ocular surface microbiota and microbial diversity in patients with pterygium after different durations of electronic device use.

Methods

This study involved 31 individuals diagnosed with unilateral pterygium. Conjunctival sac swabs were collected from both eyes, and 16S rRNA sequencing was used to identify the species and quantity of bacteria. The microbial composition was annotated and represented through comprehensive bioinformatics analysis.

Results

The alpha diversity did not differ significantly between the eyes with pterygium and the contralateral eyes. The Chao1 and Shannon indices for the eyes with pterygium of the patients who used electronic devices for extended periods were significantly higher than those for their
