Brief Summary
This study is open to adults with diabetic macular ischemia who have received laser treatment. The main purpose of this study is to find out whether people with diabetic macular ischemia can tolerate a medicine called BI 765128. In this study, BI 765128 is given to people for the first time. The study has 2 parts. Part A tests 3 doses of BI 765128. Participants get either a low, medium or high dose of BI 765128 as a single injection into the eye. If participants tolerate it well, the highest dose will be used in part B. In part B, participants are put into 2 groups randomly, which means by chance. 1 group gets BI 765128 as injection into the eye. The other group gets sham injections. A sham injection means that it is not a real injection and contains no medicine. Participants cannot tell whether they get the real injection or a sham injection. In this part, participants receive study treatment once every month for 3 months. Participants in part A are in the study for about 4 months and visit the study site about 8 times. Participants in part B are in the study for about 5 months and visit the study site about 7 times. The doctors regularly check participants' health and take note of any unwanted effects.

Dose limiting events were defined in the clinical trial protocol as any of the following occurrences in the eye being studied during the evaluation period: * development of sterile endophthalmitis and/or sterile inflammation of the vitreous of 3+ (out of 0, 0.5+,1+,2+,3+ and 4+, where 0 is clear vitreous and 4+ is an obscured vitreous) according to the NEI (National Eye Institute) Grading of vitreous haze, and anterior chamber cells of 3+ (out of 0, 0.5+,1+,2+,3+ and 4+, where 0 is no inflammation and 4+ is severe inflammation) according to the Standardization of Uveitis Nomenclature (SUN) working group (WG) grading scheme for 5 or more days; * visual loss of more than 15 letters at any given time-point; persistent intra-ocular pressure over 30 mmHg for 3 days; * and signs of vascular occlusion in a first (the main branch) or second degree (the vessel after the first bifurcation of the main branch) retinal vessel.
