Clinical Trial Summary

The surgically-harvested eye tissue (ie. vitreous-retinal proliferative membrane, outflow pathway, retinas, and pterygium) is a complex tissue responsible for maintaining intraocular homeostasis or mediating ocular pathogenesis. Dysfunction of one or more resident cell types within the tissues results in different ocular disorder, leading to vision loss, or even blindness. In this study, we aim to use single-cell RNA sequencing to generate a comprehensive cell atlas of surgically-harvested eye tissues.
