As the macroaneurysm grows, the ballooned out wall of the arteriole stretches and becomes thinner.
How is Macroaneurysm treated?
Complicated retinal arterial macroaneurysms may be directly treated with moderate-intensity laser photocoagulation with two to three rows of large-spot-size (200-500μm) immediately adjacent to the macroaneurysm, especially if visual function is threatened due to increasing edema.
