The investigators hypothesize that it is safe and effective to treat patients with choroidal neovascularisation (abnormal blood vessels growing under the retina) secondary to uveitis with Conbercept.
This will be a randomized, placebo-controlled trial. 20 patients will receive three injections of Conbercept into the affected eye (and repeated injections if required), and 20 patients will receive three sham injections requiring no needle stick, but making the patient unaware of whether or not he received active treatment.
Outcome of the two treatment groups will be compared after one year.
Primary Outcome Measures: Mean change from baseline in best corrected visual acuity [ Time Frame: 12 months ]
Secondary Outcome Measures: Mean change from baseline in retinal thickness [ Time Frame: 12 months ]
Mean number of Conbercept injections required over 12 months [ Time Frame: 12 months ]
Ocular and systemic adverse events [ Time Frame: 12 months ]
Intervention Details: Drug: Conbercept
20 patients will receive an intravitreal injections of conbercept 0.5 mg at baseline (visit 1; month 0) then a subsequent intravitreal injection at month 1 (visit 2) and month 2 (Visit 3). Patients will be reviewed every month thereafter for 12 months at which time it will be determined whether the patient requires retreatment with conbercept 0.5 mg based on measurements of visual acuity, Optical coherence tomography (OCT) findings, FFA and clinical appearance.
Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

To explore efficacy and safety of 0.5 mg conbercept ophthalmic injection for long-term treatment of polypoid choroidal vasculopathy (PCV) subjects.
To evaluate the efficacy and safety of 0.5 mg in adult patients with visual impairment due to choridal neovascularization (CNV).
The purpose of this study is to evaluate the safety, biological activity and pharmacodynamic effect of repeated intravitreal doses of hI-con1 0.3 mg administered as monotherapy and in comb...
To compare the initial versus delayed verteporfin photodynamic therapy (PDT) in combination with conbercept in patients with symptomatic polypoidal choroidal vasculopathy (PCV).
Choroidal osteoma (CO) frequently leads to progressive visual loss due to complications of secondary choroidal neovascularization (CNV).We report herein the function of optical coherence tomography an...
To report two cases of choroidal nevi associated with focal choroidal excavation (FCE) and polypoidal choroidal neovascularization (PCN).
This study investigated the potential role of sirtuin 1 in Müller glial cells in choroidal neovascularization. In the in vitro study, primary Müller glial cells were cultured and treated with resver...
To compare the efficacy of microneedle-delivered suprachoroidal (SC) pazopanib to intravitreal (Ivit) delivery of pazopanib, bevacizumab, or a fusion protein hI-con1 versus vehicle controls on choroid...
To describe the imaging features of choroidal neovascularization (CNV) associated with choroidal nevus using optical coherence tomography angiography (OCT-A) imaging.
A pathological process consisting of the formation of new blood vessels in the CHOROID.
Excessive axial myopia associated with complications (especially posterior staphyloma and CHOROIDAL NEOVASCULARIZATION) that can lead to BLINDNESS.
A form of RETINAL DEGENERATION in which abnormal CHOROIDAL NEOVASCULARIZATION occurs under the RETINA and MACULA LUTEA, causing bleeding and leaking of fluid. This leads to bulging and or lifting of the macula and the distortion or destruction of central vision.
A TIE receptor tyrosine kinase that is found almost exclusively on ENDOTHELIAL CELLS. It is required for both normal embryonic vascular development (NEOVASCULARIZATION, PHYSIOLOGIC) and tumor angiogenesis (NEOVASCULARIZATION, PATHOLOGIC).
New blood vessels originating from the corneal veins and extending from the limbus into the adjacent CORNEAL STROMA. Neovascularization in the superficial and/or deep corneal stroma is a sequel to numerous inflammatory diseases of the ocular anterior segment, such as TRACHOMA, viral interstitial KERATITIS, microbial KERATOCONJUNCTIVITIS, and the immune response elicited by CORNEAL TRANSPLANTATION.
