Design outcomes

Primary

MeasureTime frame
To evaluate efficacy of OZPRIME strategy in management of DME over a 24-week treatment period and compare with anti VEGF monotherapy regimes (Ranibizumab 0.5 mg biosimilar and Aflibercept 2mg)Timepoint: 24 weeks

Secondary

MeasureTime frame
3) To evaluate the number of injections required in eyes undergoing OZPRIME strategy and compare with anti VEGF monotherapy regimes (Ranibizumab 0.5 mg and Aflibercept 2mg). Timepoint: 24weeks;1) To evaluate the mean change of Best corrected Visual acuity following OZPRIME strategy and compare with anti VEGF monotherapy regimes (Ranibizumab 0.5 mg biosimilar and Aflibercept 2 mg).Timepoint: 24 weeks;2) To evaluate the change in retinal thickness in Optical Coherence Tomography (OCT) after 24 weeks following OZPRIME strategy and compare with antiVEGF monotherapy regimes (Ranibizumab 0.5 mg biosimilar and Aflibercept 2 mg). Timepoint: 24 weeks
