Purpose: The aim of this study was to determine the association between stigmatism and amblyopia. Methods: It was a hospital based, cross-sectional retrospective study conducted in Nepal Eye Hospital. Medical record of amblyopic children aged 13 years or younger from were reviewed. Children with amblyopic eyes due to simple astigmatism were included. Relation between depth of amblyopia with magnitude and types of astigmatism, orientation of axis was determined. Out of 139 amblyopic eyes of 82 children, 93 were simple myopic astigmatism and remaining 42 were simple hyperopic astigmatism. Results: Mean age of patients was 7.38±2.61 years. Visual acuity improved by at least one line in Snellen chart in 4/5th of eyes after astigmatic correction. Moderate amblyopia was found to be present in 45% eyes while severe amblyopia in 16% of eyes. With the rule astigmatism was found to be present in 88% eyes. Mean astigmatism was 2.47±0.98D and majority of eyes (67.7%) had high astigmatism. Depth of amblyopia was not associated with magnitude of astigmatism (p > 0.05) but number of lines improved with astigmatic correction was correlated with the magnitude of astigmatism (p < 0.001). Risk of amblyopia is more in high myopic astigmatism. Conclusion: Presenting age of amblyopic children was late in Nepal. Depth of amblyopia was not associated with magnitude of astigmatism.

Considering that few studies had paid attention to the living characteristics and social environment surrounding amblyopes, the present study surveyed the parents of children aged 3 to 12 and diagnosed-with amblyopia to analyse the time when the children were first diagnosed-with amblyopia, the characteristics of their living environment and the socio-environmental factorsand to delve into correlations. For the purpose of this study, 104 parents of patients in 4 hospitals in Seoul, Gyeonggi and Incheon consented to participate in the survey from September 2 to November 23: 2013. As for the time when the children were first diagnosed with amblyopia: the age of 4 accounted for the highest percentage(28.8%). The older the parents were: the later the children were diagnosed with amblyopia (p<.01). The higher the education of parents, the earlier the diagnosis of amblyopia(p<.05). The present findings-will be conducive to decreasing the number of patients who have no choice but to live-with low vision for life by missing some timely visual acuity tests and ophthalmological examination and particularly to developing a social safety net that can realize national medical welfare for the low-income families and the socially disadvantaged class.With the help of information technology.

For the prevention of amblyopia, early discover and treatment is very important. Therefore we evaluated the type and the degree of refractive errors of 39 children with anisometropic and refractive amblyopia aged 3 to 12 years, and studied the relationship of astigmatism and amblyopia. Astigmatism was found in 35 of 39 eyes. Of these 35 eyes, with the rule astigmatism was found in 30 eyes. The cylinderical power was distributed mostly from 0.50D to 6.50D and astigmatism did not appear to influence on the initial and final corrected visual acuity.

The purpose of this study was to determine the effects of mother's education about amblyopia occlusion therapy on parenting stress and efficacy and the visual acuity improvement of the amblyopia child. The study was designed as a nonequivalent control group pretest posttest quasi-experimental study. The mothers with amblyopia children who signed the consent form were assigned to one of two groups, the experimental group (29) and control group (31). The data were collected from March 5 to October 5, 2010, at G university hospital outpatient department located in G city. The subjects in the experimental group participated in the Mothers Education about Amblyopia Occlusion Therapy for 24 weeks, which included face to face consultations, telephone counseling, etc.. The degree of parenting stress and efficacy were measured by using questionnaires and the visual acuity was measured by visual examination. The data were analyzed using the ${\chi}^2-test$, Fisher's exact probability test, t-test and Repeated Measure ANOVA using SPSS PC+20.0 for Windows. The following results were found after the therapy. The experimental group had statistically significantly higher visual acuity (Rt, F=40.64, p<.001, Lt, F=10.28, p<.001), lower parenting stress scores (F=9.85, p=.003) and higher parenting efficacy scores (F=22.19, p<.001) than the control group. In conclusion, the Mothers about Amblyopia. Occlusion Therapy Education Program was effective in improving the visual acuity of the amblyopia children, and decreasing the parenting stress and enhancing the parenting efficacy of their parents.

The purpose of this study was to investigate effect of spectacle correction therapy instead of occlusion therapy for refractive amblyopia treatment. Spectacle correction were prescribed to give the same effect as a occlusion therapy by under correction for normal eye and there was no additional treatment but only spectacle correction for hyperopic amblyopia. The results can be summarized as follows: 1. In hyperopic amblyopia after correction, initial visual acuity($Mean{\pm}SD$) was $0.36{\pm}0.13$ and final visual acuity($Mean{\pm}SD$) was $0.82{\pm}0.23$. 2. Regardless with age, there was significant differences between initial acuity and final acuity, it shows improvement in visual acuity after spectacle correction treatment. 3. Initial correction age did not influence the length of treatment and success rate of treatment, so that ambyopia correction effect not related with age. 4. Compared with initial visual acuity with final visual acuity, initial visual acuity was in proportion to final visual acuity. 5. Incidence was higher in hyperopia and hyperopic astigmatism than myopia and myopic astigmatism in refractive amblyopia group and the therapy was more effective for hyperopia and hyperopic astigmatism than myopia and myopic astigmatism. 6. Treatment was effective even for children who is older than 8 years.

Objectives : The aim of this study is to report the effect of long-term acupuncture on a amblyopia derived from astigmatism. Methods : A 39-month-old-female child presented with decreased visual acuity with simple astigmatism and amblyopia in the left eye. She took long-term acupuncture treatment once or twice a week for almost four years. And the autorefractor follow-up were conducted per every 6 months. Results : At the initial visit, naked eye visual acuity was 0.1/0.7(OD/OS), Sph. +0.00D, Cyl. -2.25D, AXIS 148° in the right eye, and Sph. +0.00D, Cyl. -0.25D, AXIS 49° in the left eye. After acupuncture treatment for about 4 years without correctional glasses, the visual acuity of the right eye was 1.0, the right eye had Sph. +0.00D, Cyl -0.50D, AXIS 146°, and the left eye had Sph. -0.25D, Cyl -0.50D, AXIS 154°. The visual acuity was maintained until 1 year follow up as 0.9/1.0(OD/OS). Conclusions : This study shows the possibility of using acupuncture treatment for amblyopia derived from astigmatism.

Purpose: This study is to investigate if the improvement of visual sensory (VS) by amblyopia treatment affects the ocular functions in refractive errors, accommodative errors and phoria at distance and near. Methods: 10 subjects (17 eyes, mean age of $10.7{\pm}2.9$ years) who treated amblyopia completely, were participated for this study. Refractive errors, accommodative errors, and distance and near phoria were compared between before and after treatments of amblyopia. Refractive errors and accommodative errors at 40 cm were measured using openfield auto-refractor (NVision-5001, Shin Nippon, Japan) and using monocular estimated method (MEM) respectively. Phoria was determined at 3 m for distance and at 40 cm for near using Howell phoria card, cover test or Maddox rod. Results: Mean corrected visual acuity (CVA) significantly increased from $0.46{\pm}0.11$ (decimal notation) for before amblyopia treatment to a level of $1.03{\pm}0.13$ for after amblyopia treatment (p < 0.001). For spherical refractive error, hyperopia significantly decreased from $+2.29{\pm}0.86D$ to a level of $+1.1{\pm}2.38D$ (p < 0.05) but astigmatism did not significantly change; $-1.80{\pm}1.41D$ for before treatment and $-1.65{\pm}1.30D$D for after treatment (p > 0.05). Accommodative error significantly decreased from accommodative lag of $+1.1{\pm}0.75D$ to a level of $+0.5{\pm}0.59D$ (accommodative lag) (p < 0.05). Distance phoria significantly changed from eso $2.9{\pm}6.17PD$ (prism diopters) to a level of eso $0.2{\pm}3.49PD$ (p < 0.05), and near phoria also significantly changed from eso $0.4{\pm}2.32PD$ to level of exo $2{\pm}4.9PD$ (p < 0.05). There was a high correlation (r = 0.88, p < 0.001) between improvement of visual acuity and decrease of accommodative lag. Conclusions: Hyperopic refractive error decreased with improvement of CVA or VS by amblyopia treatment. And the improvement of VS by amblyopia treatment also improved accommodative error, and changed phoria coupled with accommodation.

The aim of the study was performed the wave analysis of P-VEP on the normal monocular vision and amblyopia in binocular. The P-VEP of three channels were recorded by the Nicolet system. Five adults (three males, two females, mean=22 years, range=19 to 24) subjects were recorded The subjects were researched the history including the systemic health, medication, genetics, allergy and ocular disease. Visual acuity and stereopsis were recorded for each subject monocularly and binocularly. Also subjects viewed the P-VEP stimulus both monocularly and binocularly through the corrected visual acuity during the VEP were recorded. The results of study suggest that the visual acuity of binocularly is better than with monocularly and the stereopsis was about over 140 sec. On the other hand, the analysis of P-VEP suggest that the amplitude of wave is larger when the monocular eye receives the P-VEP stimulus compared with the binocular eye. However the amplitude of wave in amblyopia had more smaller than the normal monocular The latency period of P-VEP was similar to results between the normal eye and binocular vision. But the amblyopia was a long period compared with the normal monocular and binocular vision. In conclusion, this study indicated that the visual acuity of binocularly have a better than the normal monocular vision, But in the P-VEP test, the amplitude of wave on normal monocularly vision appears to be better through the binocularly. But the amblyopia appeared the low amplitude wave of P-VEP and decreased the visual acuity.
