Fig. 5. A. Illustration of a macroaneurysm with thick sub-internal limiting membrane (ILM) hemorrhage Because the hemorrhage obscures the macula, the patient's visual acuity is poor and it is not possible to determine clinically if the hemorrhage extends beneath the macula. Nd-YAG laser photodisruption can break through the ILM. B. If the blood has not yet solidified, it may drain through the laser opening and improve visual acuity and visualization of the macula.
