Brief 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.


Eligibility criteria: Inclusion Criteria:

1. Patients with ocular diseases and require surgery intervention.
2. The surgery intervention remove pathological tissue during surgery.
3. Patients consent to the treatment and single-cell sequencing.

Exclusion Criteria:

1. Surgically removed eye tissue cannot meet with the quality control of single-cell sequencing (mainly the tissue weight and cell counts);

Primary outcomes:
