  • 목적: 학령기 아동에게 조절마비하 굴절검사를 시행 한 이후 안경착용이 근시진행에 미치는 영향에 대하여 분석하고자 하였다. 방법: 안경착용경험이 없는 8세 이상 12세 이하의 학령기 아동 33명(66안)에 대하여 근시의 진행정도를 알아보기 위하여 조절마비하 굴절검사를 기간별(초기, 100일, 200일, 300일)로 실시하였다. 안경착용군(실험군, 32안)은 최초 조절마비하 굴절검사 이후에 나안시력 0.6에 맞춰 안경을 착용하도록 하였으며 굴절이상도에 따른 안경굴절력은 -0.50 D, -0.75 D, -1.00 D, -1.25 D 그리고 -1.50 D였으며 비안경착용군(대조군, 34안)은 기간별로 조절마비하 굴절검사를 시행하였다. 실험군과 대조군에 대하여 기간별, 연령별, 굴절이상도별로 근시의 진행정도를 비교하였으며, 실험군은 안경착용굴절력값에 따른 근시의 진행정도를 관찰하였다. 결과: 조절마비하 굴절검사 300일을 기준으로, 안경착용군(실험군)에서 평균 등가구면 굴절력 -1.03 ${\pm}$ 0.43D(t=13.36, p<0.001) 증가하였고, 비안경 착용군(대조군)에서는 -0.61 ${\pm}$ 0.35 D(t=10.05, p<0.001) 증가하여 통계학적 유의성이 있었다. 안경처방값에 따라 -1.50 D에서 41.19 ${\pm}$ 15.25%, -1.25 D에서 336.74 ${\pm}$ 19.29%, -1.00 D에서 56.57 ${\pm}$ 20.21%, -0.75 D에서 87.26 ${\pm}$ 49.38%, -0.50 D에서 106.69 ${\pm}$ 59.60%가 증가하였다. 결론: 안경착용군이 비안경착용군보다 300 일을 기준으로 0.46D 더 근시진행이 빨랐으며 근시진행의 완화를 위해서는 안경착용을 하지 않는 것이 효과적이라 사료된다. 그러나, 학령기 아동에게 최초의 안경착용이 필요하다면 조절마비하 굴절검사로부터 300일 이내의 근시진행에 대하여 저교정을 고려해 볼 수 있겠다.

  • Purpose. To analyze the refractive status between urban and rural regions, of children in Korea, in the age group of 13. Methods. From October 2016 to January 2017, forty subjects( 20 male subjects, 20 female subjects; 13 years) were performed in refraction test using the Auto-Refraction. Myopia, hyperopia, astigmatism, and anisometropia were defined as spherical equivalent(SE)${\leq}-0.50$ diopters, SE ${\geq}+1.00D$, cylinder error ${\geq}0.75D$ and SE difference${\geq}1.00D$ between binocular eyes, respectively. Results. The refractive error by spherical equivalent among all subjects was myopia 76.25%, astigmatism 35%, emmetropia 16.25%, anisometropia 8.75%, and hyperopia 5%. The prevalence of myopia and astigmatism were much more common in urban than rural region although the difference was not statically significant. Emmetropia and astigmatism were much more common in rural region than urban although the difference was not statically significant. The prevalence of spherical equivalent was much common from -1.00 diopter to -4.00 diopter. On the other hand, the prevalence of myopia was much more than hyperopia. There was a statistical significance between OD and OS of rural region in the spherical equivalent power(p<.000). Also, There was a statistical significance between OD and OS of urban region in the spherical equivalent power(p<.004). Therefore, there was a significant statistical similarity between urban and rural regions on the OD and OS in the spherical equivalent power. On the other hand, There was a significant statistical similarity between urban and rural regions of the OD and OS in the astigmatism power(p<0.000). However, in the rural and urban regions there was not statistical significance in the OD and OS concerning the spherical equivalent power and astigmatism power (p>0.1). Conclusions. Myopia was the most common refractive error in Korea young children. while hyperopia was few. There was not a statistical significance as age between rural and urban at spherical equivalent power( P> 0.01). These results suggested that the analysis of the refractive status at young children can give the useful diagnosis data for the correction of visual acuity.

  • 목적: 본 연구는 근시안에서 현성굴절검사(manifest refraction: MR)와 조절마비굴절검사(cycloplegic refraction: CR)값을 비교하여 연령과 근시도에 따라 차이가 있는지 알아보고자 하였다. 방법: 근시성 굴절이상을 가진 229명 ($25.3{\pm}11.9$세)을 대상으로 조절마비제(cyclogyl 1%) 점안 전과 후에 자각적 굴절검사를 시행하였다. 결과: 조절마비제 점안 전 후 평균굴절력을 비교 조사하였더니, 근시 0.19 D, 난시 0.02 D 감소하였고 난시방향은 1.85도 차이를 보였다. 근시도의 변화는 30~40대에서 가장 높게 나타났으며, 229명(458안) 중 근시도수에서 0.50 diopter(D) 이상의 차이를 보이는 경우는 73안(16%)으로 근시도가 높은 군일수록 오차율이 높게 나타났다. 결론: 현성굴절검사와 조절마비굴절검사 값을 비교해 본 결과 연령에 따른 근시도의 변화는 유의하지 않았으나, 근시도가 높은 군일수록 오차율이 유의하게 높은 것으로 나타났다.

  • Purpose. To analysis the prevalence of the myopia and corneal astigmatism in Korea women university students. Methods. From August 2011 to December 2012, one hundreds subjects were performed in refraction test using the Auto-Keratometry. Results. The mean age of the 100 subjects (200 eyes) was $21.23{\pm}2.34$. The mean spherical refractive power was -$1.78{\pm}1.65$(OD) and -$1.83{\pm}1.67$(OS) Diopter. The mean astigmatism power was $1.22{\pm}0.96$ (OD) and $1.27{\pm}0.91$ (OS). The mean corneal astigmatism was $1.44{\pm}0.81$(OD) and $1.55{\pm}0.93$(OS). Corneal astigmatism was between 0.25 D and 1.25 D in 67.7% of eyes, 1.25 D or higher in 27.5% eyes, and less than 0.25 D in 4.8% of eyes. Astigmatism was with the rule in 65%, against the rule in 31.5%, and oblique in 3.5%. There was a statistical significance between right eye and left eye in the spherical equivalent power(p=0.002). Also there was a statistical significance between spherical power and refractive astigmatism in OD(p=0.006) and OS(0.003) and a statistical significance between corneal astigmatism and refractive astigmatism in OS(p=0.0003). However, there was not a statistical significance between spherical power and corneal astigmatism in OD(p=0.08) and OS(0.1) and a statistical significance between corneal astigmatism and refractive astigmatism in OS(p=0.48). Conclusions. In this study, these results suggested that the analysis of the refractive myopia and corneal astigmatism can provide the visual correct and useful diagnosis information for the eyewear dispensing, contact lens fitting and corneal refraction surgery.

  • Objectives: The purpose of this study was to investigate the effect of Ganjeonggyeok and eye exercise therapy in primary school students who have myopia. Methods : 76 primary school students were divided into 2 groups. Experimental group was treated with eye exercise therapy along side with Ganjeonggyeok, while control group was treated with only eye exercise therapy. We compared and analyzed the rate of recovery of eyesight after 3 months. Results & Conclusions : 1. Right eyesight of the experimental group was improved from $.59{\pm}.41$ to $.70{\pm}.48$ and it was statistically significant. Left eyesight was improved from $.63{\pm}.40$ to $.66{\pm}.45$, but it was not statistically significant. In case of control group, right eyesight was improved from $.98{\pm}.33$ to $.99{\pm}.34$, and left eyesight, from $.66{\pm}.34$ to $1.04{\pm}.44$. In both cases, the variation was not statistically significant. 2. We compared VFQ scores of each group before and after the treatment. In experimental group, the score changed from $61.54{\pm}6.8$ to $61.83{\pm}6.3$, and in control group, the score changed from $61.74{\pm}4.0$ to $60.50{\pm}.11.9$. However, there were no statistical significance in both cases. 3. Eye exercise therapy alone can help recovering eyesight. However, Ganjeonggyeok in parallel with eye exercise showed significant recovery of myopia.
