Optic disc measurements using the Heidelberg Retina Tomograph in amblyopia.

A total of 44 patients with a history of unilateral amblyopia (27 patients with persistent amblyopia and 17 patients with resolved amblyopia) were examined using the Heidelberg Retina Tomograph (HRT) II. Parameters examined included disc area, cup area, cup volume, rim area, rim volume, cup-to-disc area ratio, and mean retinal nerve fiber layer thickness.
