초록

목적: 본 연구는 성인 남녀의 근거리 입체시와 근거리 사위의 관계를 알아보고, 근거리 입체시와 사위 및 굴절이상과의 상관성을 조사하였다. 방법: 성인 83명(남자 36명, 여자 47명, 평균 연령 21.09±1.74(19~29)세)을 대상으로굴절이상자는 완전교정 후, 검사거리 40 cm에서 근거리 입체시는 Titmus-fly Stereotest(Stereo Optical Co., Inc.,Chicago, IL, USA)와 RANDOT Stereotest(Stereo Optical Co., Inc., Chicago, IL, USA), 사위는 수정토링톤법(modified torrington method)으로 측정하였다. 결과: 근거리 입체시는 남자가 여자보다 더 좋았고 남녀 간에 차이는없었으나, 근거리 사위는 여자가 남자보다 더 높았으며 남녀 간에 유의한 차이가 있었다(p<0.05). 근거리 입체시는Titmus-fly Stereotest와 RANDOT Stereotest 결과 각각 내사위에서 262.17±562.43초, 243.08±68.04초, 정위에서148.42±269.54초, 107.40±263.74초, 외사위에서 113.94±152.46초, 79.70±136.83초로 사위 세 그룹 간에는 차이가없었으나(p>0.05), 내사위와 근거리 입체시는 높은 상관성이 있었다(r=0.68). 또한 근거리 입체시가 굴절이상에서는각각 정시에서 80.00±571.43초, 68.75±36.82초, 근시에서 133.57±224.15초, 93.14±214.95초 원시에서 511.20±855.00초, 511.4±855.60초로 세 그룹 간에 유의한 차이를 나타냈다(p<0.05). 근거리 입체시를 굴절이상도로 분류했을 때, 정시에서 가장 좋고 고도 근시, 고도원시로 굴절이상도가 높았을 때 감소하였다. 결론: Titmus-fly Stereotest와 RANDOT Stereotest 결과, 성인의 근거리 입체시는 내사위일 때, 굴절이상이 높을 때 감소되어 사위 및 굴절이상과 관계가 있었고, 이 두 입체시 검사에서 근거리 입체시가 나쁠 경우에 사위 또는 굴절이상을 예상할 수 있다.

Purpose: This study was investigated the relationship between the male and female of near stereoacuity andphoria, and was examined the correlations between near stereoacuity and phoria and refractive error. Methods:Adult 83 (male 36, female 47, mean age 21.09±1.74(19~29) years old) target was examined after full correctionof refractive error. Near stereoacuity was measured by using Titmus-fly Stereotest(Stereo Optical Co., Inc.,Chicago, IL, USA), and RANDOT Stereotest (Stereo Optical Co., Inc., Chicago, IL, USA), phoria was measuredby using modified torrington method, at distance 40 cm. Results: In near stereoacuity, male was better good thanfemale, and there was no difference between male and female (p>0.05). In near phoria, female was more higherthan male, and there was a significant difference between male and female (p<0.05). Near stereoacuity byTitmus-fly test and Randot test result respectively was 262.17±562.43 sec (second of arc) 243.08±68.04 sec inesophoria, 148.42±269.54 sec, 107.40±263.74 sec in orthophoria, 113.94±152.46 sec, 79.70±136.83 sec inexophoria, there was a no difference between three phoria groups (p>0.05), and was a high correlation betweenphoria and near stereoacity(r=0.68). In addition, near stereoacuity in the refractive error respectively was 80.00±571.43 sec, 68.75±36.82 sec in myopia, 133.57±224.15 sec, 93.14±214.95 sec in hyperopia, 511.20±855.00sec, 511.4±855.60 sec, there was a significant difference between three phoria groups (p<0.05). when wasclassfiied near stersoacuity into degree of refractive error, near stersoacuity was best in emmetropia, and wasreduced when refractive error was highest in high degree myopia, and hyperopia. Conclusions: Titmus-flyStereotest and RANDOT Stereotest result, near stereoacuity of adults, when esophoria and high degree refractiveerror, was reduced, there was a relationship between near stereoacuity with phoria, and refractive error. In thisboth stereotests if was bad when near stereoacuity can expect a phoria and refractive error.
