Is this patient suitable for macular argon laser photocoagulation (refers to the enlarged picture below)?

Answer
No. There is disruption of the foveal vasculature and sign of non-perfusion. This indicates foveal ischaemia.

Is there evident of retinal ischaemia in this patient?

Answer
No. Retinal ischaemia is defined as more than 5 disc areas of retinal 
capillary non-perfusion. (Note: there are some areas of hypofluorescence due to the masking effect of retinal haemorrhages).
