To study the relationship between the refractive status of children with partial accommodative esotropia and binocular single vision.

36 children with partial accommodative esotropia were retrospectively analyzed. The naked visual acuity, corrected visual acuity, diopter after atropine dilation, near and distant residual strabismus after wearing glasses for half a year, and binocular monocular function were recorded and statistically analyzed.

36 children with partial accommodative esotropia were aged range from 3 to 14 years, with an average of (79.39±31.21) months. Equivalent spherical of right eyeball was (+ 4.45±1.73) D, and left eyeball was (+ 4.75±1.68) D. 33 cm naked strabismus was (+ 53.19±18.05) △, while, 6 m was (+ 47.50±19.00) △. 33 cm residual strabismus was (+ 30.36±12.03) △, while, 6 m was (+ 25.53±9.59) △. There is no correlation between equivalent spherical and Ⅰ, Ⅱ, and Ⅲ visual functions (r=-0.012, -0.058, -0.016; P>0.05). Equivalent spherical was positively correlated with 33 cm naked strabismus (r=0.344, P<0.05), and negatively correlated with naked visual (r=-0.456, P<0.05). 33 cm naked strabismus was negatively correlated withⅠ, Ⅱ and Ⅲ visual functions (r=-0.378, -0.678, -0.482; P<0.05), also with Titmus stereogram (r=-0.477, P<0.05). 6 m naked strabismus was negatively correlated with Ⅰ, Ⅱ, and Ⅲ visual functions (r=-0.453, -0.610, -0.430; P<0.05). 33 cm residual strabismus was negatively correlated with Ⅱ and Ⅲ visual functions (r=-0.651, -0.600; P<0.05), also with Titmus stereogram, stereofauna, and stereo circle (r=-0.688, -0.625, -0.462; P<0.05). 6 m residual strabismus was negatively correlated with Ⅱ and Ⅲ visual functions (r=-0.587, -0.543; P<0.05), also with Titmus stereogram, stereofauna, and stereo circle (r=-0.644, -0.514, -0.492; P<0.05).

The refractive status of children with partial accommodative esotropia is not related to binocular monocular function, but negatively related to naked visual acuity. The residual strabismus affects binocular monocular function.
