The embolus was fragmented (embolysis) with the Nd:YAG laser technique.
Key Words: Calcific embolus, branch retinal artery occlusion, Nd:YAG laser embolysis
Recently, the neodymium:yttrium aluminum gamet (Nd:YAG) laser was used to perform transluminal Nd:YAG laser embolysis (TYE) in patients with central retinal artery occlusion (CRAO), branch retinal artery occlusion (BRAO) and a cilioretinal artery occlusion.
The energy was increased in 2mJ increments without tissue response until the setting was placed at 6.0 mj for embolysis. Although the laser energy was applied for embolysis, a small opening was made in the arteriolar wall at the same time and just after the laser application with 6.0-mJ, suddenly subhyaloid hemorrhage developed overlying the occluded vessel area (Figure 2).
