The number, morphology, and material type of the MPs in pterygium were identified using Raman microscopy and scanning electron microscopy. Ten MPs were detected in the pterygium, which corresponded to polyethylene (PE) (n\u2009=\u20097), polystyrene (PS) (n\u2009=\u20092), and polypropylene (PP) (n\u2009=\u20091). The size of MPs ranged from 5\u20139 \u00b5m (n\u2009=\u20095, PE or PS), 10\u201319 \u00b5m (n\u2009=\u20094, PE), and 50\u201399 \u00b5m (n\u2009=\u20091, PP). All MPs were transparent and irregular fragments.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study demonstrated the detection of MPs in the pterygium tissue.
