ABSTRACT
@#AIM: To explore the effects of red light flashing therapeutic instrument combined with distance visual training through reading red visual acuity chart on myopic amblyopia in children.<p>METHODS: Totally 112 cases of children patients with myopic amblyopia treated in our hospital were assigned to the control group and the observation group. The control group was given short covering method and short-range visual function training, and the observation group was given red light flashing therapeutic instrument combined with distance visual training through reading red visual acuity chart on the basis of the above treatment. The clinical efficacy, refractive dynamic changes, the BCVA and amblyopia recurrence rate were compared between the two groups. <p>RESULTS: The total clinical effective rate in the observation group was significantly higher than that in the control group(<i>P</i><0.05). Before and after treatment, the myopic diopter was no significant difference in the observation group(<i>P</i>>0.05), the control group gradually increased myopic diopter with time(<i>P</i><0.05). The myopic refraction, the change value of average annual refraction and the recurrence rate of amblyopia after 1y of treatment in the observation group was lower than that in the control group(<i>P</i><0.05). The BCVA after 1y of treatment was significantly higher than that after 6mo of treatment(<i>P</i><0.05).<p>CONCLUSION: Red light flashing therapeutic instrument combined with distance visual training through reading red visual acuity chart for children patients with myopic amblyopia can effectively reduce the change value of average annual refraction, correct the best visual acuity, and reduce the risk of amblyopia recurrence.
ABSTRACT
·AIM: To compare intervention effects on myopic children between three groups including orthokeratology combined with visual training ( OCVT), orthokeratology (ortho-k), and single vision spectacle lense (SVL). ·METHODS: A prospective, non-randomized, case-control study was performed from September to October 2016. One hundred and twenty myopic children were enrolled from the Shaanxi Eye Research Institute and divided into three groups, which consists of 37 in OCVT group, 43 in ortho-k group and 40 in SVL group. The changes of uncorrected visual acuity ( UCVA ), axial length ( AL ) and spherical equivalent refractive error (SER) before and after 1a intervention were compared between the three groups. ·RESULTS: A total of 103 children completed the study, 31 in OCVT group, 37 in ortho-k group, 35 in SVL group. The changes before and after intervention of UCVA, AL, SER were significant differences between the three groups separately ( P < 0. 01 ). Furthermore, the improvement effect of each parameter in the SVL group was worse than that in the OCVT group and the ortho-k group (P<0. 05). Although the improvement effect in the OCVT group was slightly better than the ortho-k group, the difference was not statistically significant (P>0. 05). After 1a intervention, UCVA was greatly improved ( P<0.05), SER was reduced (P<0. 05), but AL was not significantly changed ( P>0. 05 ) in the OCVT group. In ortho-k group, UCVA was improved, SER was reduced, and AL increased significantly ( all P< 0. 05 ). UCVA decreased, as well as AL and SER increased significantly in the SVL group (all P<0. 05). ·CONCLUSION: Orthokeratology combined with visual training has a good control effect on myopic children, but the timing, method, time length and frequency of visual training still need further study.
ABSTRACT
Objective To assess the efficacy and safety of multimedia visual training system for ambly-opic children through a randomized, controlled clinical trial. Methods A total of 203 amblyopic children (253 eyes) ages 3 to 12 years were randomly divided into a study group (100 patients, 170 eyes) and a control group (103 patients, 183 eyes). The study group received multimedia training system; while the control group received conventional integrated therapies. Best corrected visual acuity was examined 3 and 6 months after treatment. The efficacy and safety of multimedia visual training system for amblyopic children was assessed by comparing the ef-fect of treatment in both groups. Results 6 months after treatment, the total effectiveness rate was 74.1% in the study group and 52.5% in the control group, and there was a statistical difference (P < 0.0001). The effective-ness rate for refractive amblyopia was higher in the study group than in the control group (80.5% vs. 50.8%), and there was a significant difference (P < 0.001). As compared with the effectiveness rate for different ages, the subgroups of 3 to 6 years and 7 to 12 years in the study group was 80.8% and 58.0%, much higher than those in the control group (54.9% and 43.9%), and there were statistical differences(P < 0.001 and P < 0.05). Conclusions The efficacy of multimedia visual training system is superior to that of the traditional treatment , especially for refractive amblyopia. It is effective in all age groups.

ABSTRACT
AlM:To observe the changes of binocular vision in V-pattern exotropia children before and after surgical correction, and the effect of training in reconstructing the binocular vision after surgical corrections.METHODS: Sixty V-pattern exotropia children were enrolled in this study and were divided into three groups according to their age:group A (4~6 years old), group B (7~9 years old), and group C (10~12 years old), 20 cases for each group. Patients received routine refraction and ophthalmic examinations. Distance and near deviation were measured by prism-covering method and synoptophore. The simultaneous perception and fusion were examined with a synoptophore, and the stereacuity was measured with stereograms ( Titmus) . The children who didn’t reconstruct binocular vision function 1wk after surgery received binocular vision training. The data were recorded before and 1 , 2, 4, and 8wk after surgery. RESULTS: Binocular vision significantly improved among the children after surgery in group A and B ( P0. 05). CONCLUSlON: V - pattern exotropia children can benefit from early surgical correction and training after surgery in reconstruct binocular vision.

ABSTRACT
Aims: To evaluate the effectiveness of visual training aimed at reducing crowding in dyslexic children. Study Design: Single-masked crossover pilot study. Place and Duration of Study: University of Turin and the Gradenigo Hospital, Department of Ophthalmology, Turin, between January and November 2013. Methodology: 15 dyslexic children underwent a visual training devised to reduce crowding. Patients were asked to recognize trigrams of letters with different spacing displayed at different eccentricities on both sides of the fixation point. As a placebo half of the sample was administered a contrast sensitivity test. Average reading rate for words and non-words with different interletter spacing was measured before and after the visual training and the placebo. The sample was divided into two subgroup: G1, who was first administered the training, and G2, who underwent first the placebo trial. Results: After the training in G1 reading rate for words increased from 1.54 syl/sec (±0.60) to 1.74 syl/sec (± 0.64) (P= .001). Reading rate for non-words improved from 0.94 (0.68-1.55) syl/sec to 1.03 (0.85-1.63) syl/sec. No significant improvement was found after the administration of the placebo (T2) when testing words and non-words Analysis of variance showed a significant placebo x treatment effect for words (P= .001) and a barely significant effect for non-words (P= .05). In G2 no significant improvement was found after the placebo both at words and non-words (from 1.69 syl/sec [±0.83] to 2.01 syl/sec [±0.94] for words, from 1.07 syl/sec [±0.51] to 1.08 syl/sec [±0.50] for nonwords). In this group the training increased the reading rate for words and non-words (from 2.01 syl/sec to 2.12 syl/sec [±1.13]; non-words: from 1.08 syl/sec to 1.22 syl/sec [±0.59]). However, analysis of variance did not show a significant effect of the treatment (words: P= .70; non-words: P= .85). Conclusion: Factors other than visuoperceptive, in particular the phonological impairment, could help to account for the controversial results obtained in the small group of dyslexic children recruited in this study. In future investigations, performed on a larger sample, a classification aimed at ruling out patients mainly affected by phonological defects should be considered, in order to select the appropriate target suitable for such kind of approach.
ABSTRACT
Objetivo: establecer la importancia de la valoración ortóptica y el entrenamiento visual antes y después de la cirugía refractiva corneal con láser, técnica Lasik.Resultados: en la evaluación pre y posquirúrgica, 6 pacientes (13.63 por ciento) no presentaron alteración oculomotora,y 37 (84.09 por ciento) reportaron algún tipo de anomalíaacomodativa o motora, de los cuales 11 pacientes (29.72 por ciento) tuvieron alteraciones combinadas, 16 (43.24 por ciento) acomodativas y 10 (37.03 por ciento) motoras. En el pre y postoperatorio las frecuencias de Hirshberg tuvieron comportamiento idéntico. En la Amplitud y la flexibilidad de acomodación no se encontraron diferencias estadísticamente significativas (p > 0.05) antes y después del Lasik, aunque desde el punto de vista clínico se evidenció un aumento en las alteracionesaltas y moderadas de la amplitud de acomodacióndespués de la cirugía refractiva, al igual que se evidenció la disminución de los valores normales de la misma, en flexibilidad disminuyeron los ojos con valores de normalidad y aumentaron las alteraciones en los niveles altos y leves. La mayoría de los pacientestuvo valores de alteración de las reservas fusionalespositivas en visión lejana entre altos y moderados. Conclusiones: clínicamente, la valoración ortóptica es necesaria en todos los pacientes que son sometidosa cirugía refractiva; aunque no se observan diferenciassignificativas entre las alteraciones motoras y acomodativas, clínicamente se observó aumento de la descompensación en la magnitud de las variablesmedidas y mayor sintomatología.
Objective: To establish the importance of valuation orthoptics and visual training before or after of the corneal refractive laser surgery, Lasik.Results: In assessing pre-and post-surgical 6 patients (13.63 percent) showed no eye motor alteration and 37 (84.09 percent) reported some kind of anomaly accommodatesor motor, of whom 11 patients (29.72 percent) had abnormalitiescombined, 16 (43.24 percent) accommodative and 10 (37.03 percent) motor. In the pre-and post-operative frequencies Hirshberg had identical behavior. In the amplitude and flexibility of accommodation dont found statistically significant differences (p> 0.05), before and after Lasik, albeit from a clinical point of view was evident increase in the alterations of high and moderate amplitude of accommodation after the refractive surgery, as is evidenced by the decrease normal values of the same, decreased flexibility in the eyes with normal values and increased disturbancesat the higher levels and mild. Most patients had values altering of the fusional reserves positive for vision near and far between High Moderate. In the values of stereopsis, the ranges of normality were stable and high and moderate alterations were correlatedwith patients with strabismic or preexisting ocular abnormalities. The next point of convergence,the cover test and the status of Correspondence Sensory did not change. 100 percent of the patients who performed visual training reported improvement in their values as in clinical symptoms.Conclusions: Clinically Orthoptics the valuation is required in all patients who undergo refractive surgery,although no significant differences between the motor impairment and accommodating, clinicallyobserved increase in the decompensation in the magnitude of the variables measured and increased symptoms.
