- With other fundus diseases (such as fertile or serious non fertile diabetic
retinopathy or diabetic retinopathy with clinical significance of macular edema,
retinal vein occlusion, macular degeneration, age, sex, blood vessel patterns change,
the pathological myopia, retinal detachment, macular hole, toxoplasmosis, optic nerve
disease, etc.);
- Demyelinating disease (including myelitis and optic neuritis) or a history of
neurology suggesting symptoms of demyelinating disease (including but not limited to
optic neuritis);
- Refractive media opacity or pupil failure that significantly interferes with visual
acuity detection, anterior segment and fundus assessment;
- One-eyed patients deemed unsuitable for inclusion by the investigator;
- Peribulbar, intravitreal or subocular corticosteroid injections were given within 30
days prior to screening;
- Posterior capsulotomy was performed within 30 days prior to screening;
- Cataract surgery is expected within 90 days prior to screening or during the study
period;
- An intravitreal injection of anti-VEGF therapy (e.g., raizumab, apecivir, or
Combocept) within 90 days prior to baseline;
- Ozurdex implants (dexamethasone implants) were performed within 6 months prior to
baseline;
- Treatment with intravitreal injection of methotrexate within 90 days prior to
baseline;

- Subjects meet any of the following criteria associated with latent or active
tuberculosis (TB) infection:
. A history of active TB = 3 years before screening (but can also be included if it is
> 3 years and documented completion of adequate treatment); B. Signs or symptoms
suggestive of active TB at the time of screening in the history and/or physical
examination; C. Recent close contact with someone with active TB; D. If a TB infection
T-cell test is positive at the time of screening, subjects will be excluded from the
study if their first TB infection T-cell test is inconclusive. For suitable standards
has been completed before screening latent TB treatment and no other risk factors,
imaging findings, or support the latent or signs of active TB specific subjects, for
positive or uncertain results may be the exception handling, researchers with the
qualified physician judgment, tuberculosis (including extrapulmonary) risk, decision
and discuss with bidders;
- Positive hepatitis C antibody during screening; Or HIV antibody positive; Or treponema
pallidum antibody positive;
- Symptoms of severe, progressive or uncontrollable kidney, liver, blood,
gastrointestinal, lung, cardiovascular, neurological or brain disease. The
investigator felt that participating in the study placed patients at unacceptable
risk.
- Patients with malignant tumors.
- Patients with moderate to severe heart failure (New York Heart Society Grades 3-4).
- History of severe allergy or anaphylactoid reaction to monoclonal antibodies.
- Prior treatment with anti-TUMOR necrosis factor TNF or other biological agents with
potential therapeutic effect for uveitis (excluding intravitreal anti-VEGF drugs).

therapy increased or did not meet any of the following conditions: methotrexate
MTX=25mg/ week; Cyclosporine =4 mg/kg/ day; Mycophenolate (or equivalent dose of
mycophenolate) =2g/ day; Azathioprine =175 mg/ day; Tacrolimus oral =8 mg/ day.
- Received clinical trial drug intervention within 3 months prior to screening.
- Received any live vaccine within 3 months prior to receiving the first dose of the
study drug, or planned to receive live vaccine during the study period.
- There are contraindications to dilatation drugs.
- Patients judged unsuitable for inclusion by other investigators
