Araki S, et al. - A comparative assessment was performed of the macular retinal and choroidal thickness in amblyopic eyes to that in fellow and normal eyes, with the aid of the swept-source optical coherence tomography (SS-OCT). There was no marked variation in inner retinal thickness in patients with unilateral amblyopia. Despite notable differences in choroidal thickness with hyperopic anisometropic amblyopia, no prominent variation was reported for the strabismic amblyopia. The discrepancy in choroidal thickness between the two types of amblyopia could be attributed to both differences in ocular size and underlying mechanism.
