Hello, as per the papers ,your relative is suffering from severe diabetic retinopathy , we call it PDR stage in our language.
The paper mentions " both eyes inferior vitreous haemorrhage' , which means bleeding inside the eye.
And the image shows macular oedema , that is filling of fluid in the exact area from which we can see.
Both bleeding and oedema are side effects of diabetic eye disease. U have already done PRP laser for bleeding. So that might need to be repeated , and more importantly to take injections or permanent visual loss can happen
Next Steps
take anti VEGF injections as advised
