As sildenafil inhibits PDE6 in retinal cells I can see why it causes colour distortion and light sensitivity. But why should the effect be more severe in coronary patients where the effect is on PDE5. Is it a different effect on vision through change in blood pressure or a is it a synergistic effect??
