Overall microangiopathy (retinopathy, neuropathy and\/or nephropathy) was present in 74%, and overall macroangiopathy (CAD, PAD and\/or TIA\/stroke) in 45%. The TT genotype did not translate into a more severe vascular phenotype, as TT patients carrying the proposed risk genotype did not suffer a higher rate of micro\u2010 and macrovascular complications. On the other hand, erectile dysfunction, present in 60% of males (<jats:italic>n<\/jats:italic>\u2003=\u2003135), was much more prevalent in TT males: 57% [GG &amp; GT] vs. 93% in TT (p 0.0088). Ocular hypertension\/glaucoma frequency (18% of the whole group) was also markedly different, albeit in opposing directions, between eNOS G894T gene polymorphism subgroups: 21% [GG &amp; GT] vs. 0%
