case_images: (a) A 50-year-old male with bilateral optic neuropathy with CAS 9 in both eyes. (b) Six months after bilateral orbital decompression with resolution of optic neuropathy and CAS 2 in both eyes.

case_images: His visual acuity was 20/60 in both eyes with impaired color vision (Figure 2(a)). Six months after bilateral orbital decompression, his visual acuity was 20/20 in both eyes with full color vision (Figure 2(b)).  His post-operative CAS was 2 in both eyes at 6 months of followup.

case_images: (a) A 49-year-old female who failed intravenous and oral corticosteroids with bilateral optic neuropathy and CAS 9 in the right eye and 10 in the left eye. (b) Computed tomography of her orbits showed enlarged extraocular muscles and orbital apex crowding. (c) 12 weeks after bilateral orbital decompression with resolution of optic neuropathy and CAS 2 in both eyes.

case_images: fig3
case_images: Her visual acuity was 20/80 in the right eye and 20/70 in the left eye with impaired color vision in both eyes (Figure 3(a)). Computed tomography of her orbits showed enlarged extraocular muscles and orbital apex crowding (Figure 3(b)). After bilateral orbital decompression, her vision was 20/20 in both eyes with resolution of color vision defects (Figure 3(c)).

case_images: (a) A 47-year-old female with right optic neuropathy. Her preoperative CAS was 10 in the right eye and 9 in the left eye. (b) 8 weeks after unilateral, right orbital decompression, she had resolution of her right optic neuropathy. Her postoperative CAS was 3 in the right eye and 4 in the left eye. (c) 6 weeks after left orbital decompression for disfiguring proptosis, with symmetric exophthalmometry measurements.

case_images: fig4
case_images: She also had impaired color vision in the right eye (Figure 4(a)). After right orbital decompression, her visual acuity was 20/25 in the right eye with resolution of optic neuropathy (Figure 4(b)). She later had left orbital decompression for disfiguring proptosis, with symmetric exophthalmometry measurements (Figure 4(c)).
