How to find the domain of this complex function????

Posted 10 years ago
0<arg((z+i)/(z-i))<Pi/4 

Some help would be apreciated!!! Thanks!

In[3]:= Reduce[0 <= Arg[(z + I)/(z - I)] <= \[Pi]/4, z]

Out[3]= (Re[z] == 0 && (Im[z] <= -1 || Im[z] > 1)) || (0 < Re[z] < 
    1 + Sqrt[2] && (Im[z] <= -Sqrt[1 + 2 Re[z] - Re[z]^2] || 
     Im[z] >= Sqrt[1 + 2 Re[z] - Re[z]^2])) || Re[z] >= 1 + Sqrt[2]
