The natural history and CT appearance of acquired hyperopia with choroidal folds

Seven healthy adults with acquired hyperopic change in refractive error had choroidal folds in affected eyes. High resolution computerized tomographic scanning techniques used to obtain coronal, oblique coronal, and parasagittal reformations revealed flattening of the posterior globes and mild to moderate optic nerve enlargement. In 5 of 11 eyes, a space was noted between the optic nerve and its sheath, implying expansion of the sub-arachnoid perineural compartment. The clinical findings and natural history of this syndrome, based on an average follow-up of 4.5 years, are discussed.
