A) When the forceps picked up the epiretinal tissue, the inferior temporal retinal artery was accidentally involved (yellow arrow) and broken off. B) The broken artery (white arrows) was floating and pulsating in the vitreous space. Microscopic bleeding at the broken end and oozing from the retinal cleft that had once enfolded the artery were observed.

While the ERM/posterior hyaloid membrane visually enhanced with triamcinolone (TA) was peeled, a movement of the forceps unintentionally involved the inferior temporal branch artery near the inner edge of the staphyloma (Figure 1A (Fig. 1)). The artery was immediately avulsed and amputated, and began pulsating and floating in the vitreous space (Figure 1B (Fig. 1)).
A) Preoperative: Path of the inferior temporal artery is indicated by white arrows. B) Postoperative: The artery (white arrows) is broken and curled up above the optic disc. C) Pattern deviation of visual field perimeter (Humphrey Field Analyzer, 30-2 program; Carl Zeiss Meditec, Inc., Dublin, CA, USA) obtained postoperatively from the patient's left eye. The superior nasal field was lost.

The inferior temporal artery in the preoperative fundus image (Figure 2A (Fig. 2)) was curled up into the vitreous space postoperatively (Figure 2B (Fig. 2)). The superior nasal visual field was lost (Figure 2C (Fig. 2)).
