A 56-year-old man developed a nasal field defect in his left eye 3 months after a traumatic accident. An examination showed a posterior subcapsular cataract in the left eye with no neurologic deficits. Humphrey 24-2 visual field testing revealed a nasal hemianopsia in the left eye. After cataract extraction and intraocular lens implantation, the patient's visual field returned to normal. This case shows that a cataract can present with a localized visual field deficit, which may be corrected by cataract extraction.
