| description | AIM: To observe the curative effect of vision therapy on children with functional visual loss.<p>METHODS: Totally 22 children with functional vision loss were enrolled in our department between January 2018 and June 2018, including 12 males and 10 females, the mean age 7.5±0.8 years old. All patients had routine eye examinations, refraction and binocular visual function examinations. Children with or without astigmatism whose diopter spherical mirror was between±1.00D and were accompanied by astigmatism less than ±1.00D participated in personalized vision therapy. Paired <i>t</i> test was used to analyze the binocular visual function before and after vision therapy.<p>RESULTS: The average visual acuity of the 22 children were improved, but the diopters before and after vision therapy were -0.011±0.573D and -0.057 ±0.338D drespectively, without statistical significance(<i>P</i>=0.633). The average of the distant level phoria(DLP)before and after vision therapy were -3<sup>△ </sup>±2.97<sup>△ </sup>and -1.18<sup>△ </sup>±1.6<sup>△</sup>, which was not statistically significant(<i>P</i>=0.089). The near level phoria(NLP)were -6.27<sup>△ </sup>±4.56<sup>△ </sup>and -2.82<sup>△ </sup>±2.56<sup>△</sup>; the near point of convergene(NPC)were 7.73±2.15 and 3.05±0.69cm; the accommodation convergence/accommodation(AC/A)were 2.00±1.55, 3.64±0.5 before and after the training respectively(<i>P</i><0.05); The negative relative accommodation(NRA)and positive relative accommodation(PRA)before vision therapy were 1.61±0.41 and -1.98±0.71D; after training they were 2.09±0.23 and -3.89±0.71D respectively; binocular crossed-cylinder(BCC)was 0.09±0.38D, which improved to 0.39±0.13D after therapy; the average of amplitude of accommodation(AMP)were 9.55±2.54 and 11.55±1.13D; binocular accommodation facility(BAF)were 3.36±2.73 and 9.64±1.5cpm respectively before and after therapy.<p>CONCLUSION:It is necessary to perform binocular visual function examination base on the refractive examination for children with functional vision loss. Visual therapy can improve visual acuity and binocular vision function. |
