An Argument Against Axial Length–Disc Area Ratio as the Causeof Esotropic Amblyopia

Arch Ophthalmol. 2004;122(11):1732. doi:10.1001/archopht.122.11.1732-a

I read with interest the article by Dr Lempert1 inthe June 2003 issue of the ARCHIVES. The author reports axiallength and disc areas for hyperopic patients with and without esotropia andamblyopia. In this article, he states that “reductions in disc areaare consistently found in eyes with esotropia with and without amblyopia.”In addition, he comments that in patients with amblyopia the eyes with poorervision have a greater relative reduction in disc area. As a result of thesefindings, he states that “a paucity of nerve fibers may be a factorin the explanation for decreased visual acuity in amblyopic eyes.”
