Purpose: This study aimed to report a case of microplastics (MPs) detection in a pterygium patient's tissue.
Case Report: A pterygium specimen was obtained from the right eye of a 43-year-old woman by surgical removal of a recurred pterygium. 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 = 7), polystyrene (PS) (n = 2), and polypropylene (PP) (n = 1). The size of MPs ranged from 5-9 µm (n = 5, PE or PS), 10-19 µm (n = 4, PE), and 50-99 µm (n = 1, PP). All MPs were transparent and irregular fragments.
Conclusions: This study demonstrated the detection of MPs in the pterygium tissue. Our findings suggest that environmental hazards, such as MP, may be commonly exposed to the ocular surface.

We describe a novel technique for recurrent pterygium and assess the advantage of properties of extended tenonectomy, amniotic membrane transplantation, and limbal epithelial transplantation in terms of recurrence rate, postoperative symptoms, postoperative orthoptics, and other complications. A total of nine eyes with recurrent pterygium underwent PERMISLET, i.e.

Pterygium is an ocular disease in which the conjunctival tissue invades the cornea. When the pterygium tissue reaches the pupillary region, the visual function of the patient is affected. Currently, surgical removal is the only effective treatment.

Background: Pterygium is a complex ocular surface disease characterized by the abnormal proliferation and growth of conjunctival and fibrovascular tissues at the corneal-scleral margin. Understanding the underlying molecular mechanisms of pterygium is crucial for developing effective diagnostic and therapeutic strategies.
Methods: To elucidate the molecular mechanisms of pterygium, we conducted a differential gene expression analysis between pterygium and normal conjunctival tissues using high-throughput RNA sequencing.

Purpose: To characterize corneal and conjunctival abnormalities (CCAs) and their impact on visual acuity in a cohort of survivors from the Western African Ebola virus disease (EVD) outbreak.
Design: A post hoc analysis of 121 patients, who had previously undergone screening for the Ebola Virus Persistence in Ocular Tissues and Fluids study, was performed.
Methods: Patients underwent a comprehensive ophthalmic exam at the Lowell and Ruth Gess Eye Hospital in Freetown, Sierra Leone.
