Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||12 Years - 90 Years|
- - 1) patients with circumscribed choroidal haemangioma who was diagnosed using ophthalmoscopy, fluorescein/indocyanine green angiography, and ultrasonography; 2) presence of reduced visual acuity or metamorphopsia; and 3) subretinal fluid involving the fovea.
- - patients with abnormal liver function test results, liver disease, porphyria, or previous treatment for circumscribed choroidal haemangioma.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

|Circumscribed Choroidal Haemangioma|
This prospective clinical trial aims to evaluate the safety and effectiveness study of intravitreal conbercept injection as the primary treatment for exudative circumscribed choroidal haemangioma: (1)To evaluate therapeutic effect (including both anatomical and functional responses to intravitreal conbercept injection) of intravitreal conbercept injectionfor exudative circumscribed choroidal haemangioma; (2)To evaluate the safety (including side effects of the eye as well as side effects of system) of intravitreal conbercept injection for exudative circumscribed choroidal haemangioma.
Experimental: Treatment group
The patients in the treatment group receive three monthly intravitreal injection of conbercept followed by PRN rescue treatments such as intravitreal injection of conbercept, laser photocoagulation (when outside the macular) or photodynamic therapy (when in the macular).
Drug: - conbercept
After three monthly injections of conbercept, if no effects was seen in the patients, the patients will receive rescue treatments such as photodynamic therapy (in the macular) or laser photocoagulation (outside the macular).
