  • Purpose: The purpose of this study was to investigated the effect of vision training methods on the visual function and sensation symptoms of patients with convergence insufficiency. Mehtods: The vision training observation group included 35 clients who had binocular vision disorders without opthalmic diseases or vertical phoria. They took the each vision training once a week for eight weeks and were investigated for the function and sensation symptoms changes of binocular vision. Results: According to the results, all vision training methods showed improvement of binocular vision function and sensation symptoms. For Worth 4 Dot test, Titmus test and red lenses observed the changes in fusion rate, all the training methods showed similar improvements.

  • Purpose: We developed the MYSTERY CIRCLE vision training program which was suitable for Korean people. We compared it with the established programs, Block string and Anaglyphs in aspect of functional, sensory, and symptomatical changes of binocular vision. Mehtods: The vision training observation group included 75 clients (male=40, female=35) who had binocular vision disorders without opthalmic diseases or vertical phoria. Results: According to the results, all training methods showed improvement of binocular vision function, sensation and symptoms. But the Block String had low participation, reference rate of subjects and success rate and showed the different degree of improvement depending on individuals. Anaglyphs method showed high participation and improvement. But it had a low degree of success rate and preference rate. Conclusions: MYSTERY CIRCLE method showed the highest participation, reference rate of subjects, success rate, and high degree of improvement. Therefore we suggest that MYSTERY CIRCLE is an effective and alternative method for binocular vision disorder therapy.

  • To investigate whether vision therapy (vision training) are an effective way to influence the near point of convergence, fusion range and asthenopic symptoms in convergence insufficiency. For one chosen patient who had convergence insufficiency, vision therapy (vision training) was prescribed for 4 weeks. 4 weeks later vision therapy (vision training) was quite effective in convergence insufficiency. That is, vision therapy (vision training) was an effective means of reducing symptoms, improving fusion range and decompensating exophoria in patient with convergence insufficiency.

  • I performed the refraction and binocular test for study of binocular abnormalities. The problems of the accommodation and binocular on subjects was need to the correction of the refractive error. also the subjects was need to a specific treatment for each of the problems. On two patients who had convergence excess, The full corrections of eyeglasses or (+)ADD for near vision were prescribed and the subjects trained for 4 weeks. After 4 weeks, the unconvenience of near vision have more decrease, and the objective test have good results. On clinical, If the optical correction and vision therapy was applied the treatment for binocular abnormalities. The continuous research of vision training in binocular abnormalities will be good results for treatment of several binocular abnormalities in the future.

  • Purpose: This was a study of the effects of the vision training on binocular function and sensory anomaly for intermittent exotropia and recurrent intermittent exotropia patients. Mehtods: The change was examined weekly at the clinic during the 8 week vision training. The sample group of 17 patients, intermittent exotropia and recurrent intermittent exotropia patients without amblyopia, were chosen from the patients with the short and the long-distance deviation angle p=0.558 and p=0.338, and also greater than 10${\Delta}$, respectively. Results: The longdistance deviation angle was reduced by 67.9(${\pm}$32.7)%, and the short-distance deviation angle by 75.4(${\pm}$32.9)% after the vision training. There is an improvement on the binocular function and sensory anomaly according to the fusion reverse and Worth 4 dot tests. Conclusions: This study shows that the vision training is effective for phoria, function and sensory anomalyon of the intermittent extropia and recurrent intermittent exotropia patients.

  • Purpose: This study was to examine how decline of visual function affects visual perception by assessing visual perception after improving visual function through visual training, and observing the change in the cognitive ability of visual perception. Methods: This study analyzes the visual perceptual evaluation (TVPS_R) of 23 children below age 13($8.75{\pm}1.66$) who have visual abnormalities, and improves visual function after conducting vision training (vision therapy) of the children. Results: Convergence increased from average $3.39{\pm}2.52{\Delta}$ (prism) to $13.87{\pm}6.04{\Delta}$ in the measurement of long-distance disparate points, and from average $5.48{\pm}3.42{\Delta}$ to $18.43{\pm}7.58{\Delta}$ in the measurement of short-distance disparate points. Short-distance diplopia points increased from $25.87{\pm}7.33cm$ to $7.48{\pm}2.87cm$, and as for accommodative insufficiency, short-distance blur points increased from $19.57{\pm}7.16cm$ to $7.09{\pm}1.88cm$. In the visual perceptual evaluation performed before and after improving visual function, 6 items except visual memory showed statistically significant improvement. By order of significant improvement, response gap was highest with $17.74{\pm}16.94$(p=0.000) in visual closure, followed by $15.65{\pm}17.11$(p=0.000) in visual sequential-memory, $13.65{\pm}16.63$(p=0.001) in visual figure-ground, $12.74{\pm}18.41$(p=0.003) in visual form-constancy, $6.48{\pm}10.07$ (p=0.005) in visual discrimination, and $4.17{\pm}9.33$(p=0.043) in visual spatial-relationship. In the visual perception quotient that added up these scores, the response gap was $15.22{\pm}8.66$(p=0.000), showing a more significant result. Conclusions: Vision training enables efficient visual processing and improves visual perceptual ability. It was confirmed that improvement of visual function through visual training not only improves abnormal visual function but also affects visual perception of children such as learning, perception and recognition.

  • Purpose: The purpose of this study was to investigate the change of contrast sensitivity by prescribing tinted lenses and to provide the clinical manual. Methods: Contrast sensitivity was measured for twenty adults with normal vision while they wore yellow, orange and green tinted lenses. To measure contrast sensitivity, the 5 spatial frequencies (2, 4, 6, 8 and 10 cpd) were used for 33 ms and 233 ms, respectively. Results: The contrast sensitivity was overall higher with 233 ms than 33 ms (p<0.05). The peaks of contrast sensitivity with 33 ms and 233 ms were 1.75 log unit with the yellow lens and 1. 85 log unit without the color respectively. However, there was no significance between the yellow and orange tinted lens (p>0.64) Conclusions: Yellowish tinted lens that reduces chromatic aberration and the scattering is prescribed for the various purposes to improve visual functions. Before prescribing tinted lens, identifying characteristic of user and tinted lens for cut off wavelengths is recommended.

  • Purpose: This study was designed to investigate the current status of visual acuity for elementary school students in Muan-gun and to analyze improvements of their visual function after vision training for the elementary school students who have either insufficiency of accommodation or vergence. Methods: Subjective refraction, objective refraction and binocular function were examined for 335 elementary school children from year 1 to year 6 live in Muan area, and then 47 students who have symptoms of binocular dysfunction among them were selected. We analyzed and compared between before and after vision training (VT) in binocular vision function results. Results: The results show that most of the subjects had much problem in near point convergence (NPC) than accommodation. After the vision training, the average of subjects NPC was improved about 5.93 cm, from $11.57 {\pm}1.850$ cm for before VT to $5.66{\pm}0.965$ cm for after VT. After VT positive fusional vergence at near distance after VT was $19.64{\pm}3.66$ $\Delta$, which was as much as double of near phoria. Accommodative amplitude was improved from $10.02{\pm}2.566$ D for before VT to $12.30{\pm}1.397$ D for after VT, which similar to mean of expected accommodative amplitude of 11.27 years old. Conclusions: Among insufficiency of accommodation and vergence NPC was improved specially, and accommodative facility and other ocular functions were also improved. Therefore, it is considered the vision training is very effective to recover from visual function problems.
