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

Figure 3

Clinical presentations of a patient with thyroid eye disease experience severe vision loss after the decompression surgery (case 2). The patient reports decreased vision to number of digits after an uneventful fat-removal orbital decompression. (a) Color fundus photography shows significant disc edema. The image is blurry due to corneal edema. (b) Fluorescein angiography shows disc leakage. The clinical presentations are compatible with anterior ischemic optic neuropathy. (c) Despite the prompt treatment, the optic disc becomes pallor. (d) The optical coherence tomography scan shows diffuse retinal nerve fiber layer loss, and the average thickness was 54 μm. (e) The mean deviation of visual field test is -33.34 dB.
