Lack of GPs’ knowledge was also noticed when we asked a question on the treatment options for DR patients; 60 GPs chose laser photocoagulation as a treatment option for DR patients, 4 GPs selected vitrectomy, and the rest 12 GPs were unaware about LASIK, intravitreal injections, and anti-VEGF or steroid therapies as treatment for retinopathy patients (Figure 5(a)). This evidence concerns the gene VEGFA and retinal disorder.
