Fundus examination showed persistent sclerosis of the RAM, with reduced lipid exudate in the macula (Figure 4(a)).
In the iStent group, the flow density (whole en face), as measured in the superficial and deep OCT angiogram of the macula and in the RPC of the ONH, improved significantly after surgery (superficial OCT angiogram: before: 44.6 [+ or -] 2.9; after: 47.6 [+ or -] 4.5; p = 0.002; deep OCT angiogram: before: 50.9 [+ or -] 3.6; after: 53.0 [+ or -] 4.2; p = 0.034; RPC: 43.5 [+ or -] 7.7; after: 45.4 [+ or -] 6.5).
