On follow-up visits, photophobia remained severe, visual acuity was counting fingers OU, and the visual field was markedly constricted under photopic conditions bilaterally. However, under very dim illumination, visual acuity improved to 20/400 OU and the visual field expanded in each eye. Vitreous cells disappeared and bilateral optic disc atrophy ensued. After 8 months, bilateral macular atrophy with a bull’s-eye appearance was obvious in both eyes (Figure 1C). The patient's condition remained stable for 4 years with unchanged visual acuity, visual fields, and full-field electroretinographic results. He eventually died of recurrence of his primary lung cancer. No autopsy was performed.
