Unilateral peripapillary myelinated nerve fibers with myopia and/or amblyopia
H. M. Hittner and J. H. Antoszyk
This report describes 12 patients with unilateral peripapillary myelinated
nerve fibers associated with myopia and/or amblyopia. Seven patients had
myopia with a mean of -13.00 diopters of anisometropia and abnormal maculae
varying from a decreased reflex to pigment dispersion. These patients had
final visual acuities of 20/200 or less following conventional amblyopia
therapy. In contrast, five patients had myopia with a mean of -3.75
diopters of anisometropia and normal maculae. These patients had final
visual acuities of 20/30 or greater with identical therapy. There was a
statistically significant difference between the mean diopters of
anisometropia of these two groups. However, the range of diopters of
anisometropia overlapped, and the critical feature that determined which
patients could achieve good vision was the macular appearance. This
condition is distinct from simple unilateral myopia with amblyopia and from
myelinated nerve fibers without myopia or amblyopia.
