The Changes in Optic Nerve after Orbital Decompression Surgery for Thyroid Eye Disease and Case Reports of Ischemic Optic Neuropathy

Figure 4

Clinical presentations of a patient with thyroid eye disease experience severe vision loss after the decompression surgery (case 3). The third patient reports progressive loss of vision after an uneventful fat-removal orbital decompression. (a) Initially, color fundus photography showed disc edema. (b) Visual field test shows a superior defect, and the mean deviation is -25.06 dB. Two days later, the vision decreases to the hand motion level. (c) Color fundus photography shows the progression of disc edema. There are also a cotton-wool spot and disc hemorrhage. (d) There are also some triangular, well-defined, patchy choroidal ischemic lesions (arrow). (e) Fluorescein angiography reveals marked delayed choroidal perfusion and late staining of the patchy lesions. The clinical presentations are compatible with posterior ciliary artery occlusion.
