Figure 2

Fluorescein angiography obtained in cat eyes after triolein fat embolism. (a–d) Multiple hyperfluorescent and hypofluorescent patches are observed, representing perfused and embolized choriocapillaris lobules. Red dots and circles represent the locations of the perfused and embolized terminal arterioles, respectively. The expansion of the hyperfluorescent area clearly demonstrates the blood flow beyond the boundary of each lobule (arrowheads). (e–h) Sectorial hyperfluorescence and hypofluorescence represent the occlusion of the short posterior ciliary arteries. After approximately 10 seconds, perfusion defects were resolved without any subsequent defects.
