One example is that a clinical trial of 312 macular edema participants reported that 8.0% had IOP elevation more than 10 mmHg after intravitreal anti-VEGF injections (Aref et al., 2021), which reminds us to be cautious to apply anti-VEGF treatment for secondary glaucoma after cataract surgery as mentioned above. Here, VEGFA is linked to macular retinal edema.
