Figure 9.13. Papillitis. A 22-year-old woman noticed a sudden decrease in vision in her right eye and pain on eye movement. The disc is elevated and the margins blurred, with opacification of the nerve fiber layer inferiorly. The contralateral disc is normal.

Figure 9.14. Optic nerve atrophy. A 30-year-old man developed retrobulbar neuritis in the right eye. His initial vision was 20/200. Four months later, temporal pallor of the right disc was seen (left), but vision had improved to 20/25. The left disc was normal.
