History
This 47 year old woman was noted to have nystagmus and reduced visual acuity (wouldn't follow a toy) when she was 12 weeks old. She was initially diagnosed with spasmus nutans because of head nodding. At age 3 the diagnosis was changed to ocular albinism. At age 11 her diagnosis was changed to cone degeneration.
