HH is a 9-year-old child who failed his vision test in school. He had first noted problems the previous summer that he characterized as difficulty in seeing in dim light. His parents took him to an optometrist who documented vision in the right eye of 20/25 and the left of 20/20. Cycloplegic refraction was +1.00 OD and +0.50 OS. The fundus exam showed mild choroidal folds on the right while the optic discs had a normal appearance. Exophthalmometry measured 18 mm bilaterally.
