Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

the goal of this observational study is to the find the molecular mechanisms underlying the prognosis process of Retinal vein occlusion in patients with retinal vein occlusion . The main question it aims to answer is:

What are the changes in protein in the aqueous humor during treatment in patients who are sensitive to anti-VEGF drug therapy?

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Cystic or diffuse edema in the macular area, retinal vein tortuous dilation with hemorrhage
* Optical coherence tomography (OCT) examination showed that the macular area was raised, edema and thickened
* Monocular disease, baseline central retinal thickness (CRT) ≥ 250mm
* Intravitreal injection, laser photocoagulation and blood circulation and blood stasis removal drugs were not treated before surgery
* The patient had normal blood pressure, negative urine protein, normal liver and kidney function, and normal electrocardiogram

Exclusion Criteria

* Patients with fluorescein fundus angiography (FFA) showing a large area (10 optic disc areas) without perfusion requiring retinal photocoagulation
* Patients with chronic dacryocystitis, glaucoma, cataract, severe proliferative vitreoretinopathy or vitreous hemorrhage, epi macular membrane or macular ischemia, diabetic retinopathy, age-related macular degeneration, ocular trauma and other diseases
* Intravitreal therapy or laser photocoagulation with corticosteroids or anti-VEGF drugs within three months before the study
