Who is a good candidate for it?

Ideal candidates include patients with proliferative diabetic retinopathy (PDR) or macular edema secondary to retinal vein occlusion who have not responded adequately to anti-VEGF therapy alone. Contraindications include active ocular infections, uncontrolled glaucoma, recent intraocular surgery, or known hypersensitivity to conbercept or any component of the injection. A thorough preoperative evaluation by a retinal specialist is required to confirm suitability.
