PURPOSE. To investigate color vision and its relation with the type of ambl
yopia and visual acuity of amblyopic eyes.
METHODS. In this prospective study, 67 amblyopic eyes of 64 patients, aged
from 4 to 13 years (mean 6.8 +/- 2.1) and 26 eyes of 13 control subjects ag
ed from 5 to 13 years (mean 7.3 +/- 1.6) were examined with the Farnsworth-
Munsell 100 Hue Test (FM-100). Amblyopic eyes were grouped as strabismic (2
1 eyes) and anisometropic (46 eyes). Each group was subdivided according to
their visual acuity, as less than 5/10 and 6/10 or better. The total error
s, blue-yellow (B-Y) and red-green (R-G) partial error scores were obtained
for each group. One-way ANOVA was used to assess differences between group
s.
RESULTS. The error scores of all axes were lower in the control group than
the amblyopic groups (p<0.001), but the differences within amblyopic groups
were not significant (p>0.05).
CONCLUSIONS. Deficient color vision in the amblyopic eyes was not related t
o the visual acuity and type of amblyopia.
