A Comparative Analysis of increased along with the age presbyopic additions in city and island villages

도시와 섬마을 노안의 연령에 따른 근용 가입도의 비교 관찰

This study examines how the average presbyopic additions and eye refraction state of old ages in city may be different to that island. There were 677 of the old who were 50 or over 90 in the sample. The visual acuity test was done by objective and subjective methods and used for near-chart program. The far-point refraction state and power of the additions lens results were as follows ; 1. Of far-point refraction state in city peoples; male: emmetropia 10%, myopia 17%, hyperopia 19%, mixed astigmatism 38%, etc. 16% female : emmetropia 20%, myopia 20%, hyperopia 20%, mixed astigmatism 27%, etc. 13% 2. Of far-point refraction state in island villages ; male : emmetropia 13%, myopia 17%, hyperopia 22%, mixed astigmatism 40%, etc. 8% female : emmetropia 7%, myopia 13%, hyperopia 26%, mixed astigmatism 44%, etc. 10% 3. Average presbyopic additions states has been presented no discrimination ; male: 50 to 60 : +1.25 or +1.50D, 61 to 65 : +1.75 or + 2.00D, 66 to 70 : +2.25 or +2.50D 71 to 75 : +2.75 or +3.00D, 76 to 80 : +3.25 or +3.50D, over81 : +3.75D female : 50 to 60 : +1.25 or + 1.50D, 61 to 65 : +1.75 or + 2.00D, 66 to 70 : +2.25 or +2.50D 71 to 75 : +2.25 or + 2.50D, 76 to 80 : +2.75 or +3.00D, over81 : +2.75 or +3.00D 4. Under the condition of wearing lens, the average working time was 1 or 2 hour but some people used over 5 hours. 5. Generally, it has been investigated the old ages peoples has ocular diseases and cataract was the most common.

본 연구는 도시(목포시)와 섬마을 노인(조도면)의 굴절상태와 근용가입도의 비교 연구를 50세에서 90세까지 총 677명을 대상으로 원용과 근용 타각적 굴절검사와 자각적 굴절검사를 자동굴절검사기, 검영기, 검안경, 시험 렌즈셀, 시시력표 등을 이용하여 검사한 결과는 다음과 같다. 1. 도시(목포시) 노인의 원용굴절상태 남자 : 정시 10%, 근시 17%, 원시 19%, 혼합난시 38%, 기타 16% 여자 : 정시 20%, 근시 20%, 원시 20%, 혼합난시 27%, 기타 13% 2. 섬마을(조도면) 노인의 원용굴절상태 남자 : 정시 13%, 근시 17%, 원시 22%, 혼합난시 40%, 기타 8% 여자 : 정시 7%, 근시 13%, 원시 26%, 혼합난시 44%, 기타 10% 3. 연령과 성별에 따른 근용 가입도수 남자 : 50 to 60 : +1.25 or +1.50D, 61 to 65 : +1.75 or +2.00D, 66 to 70 : +2.25 or +2.50D 71 to 75 : +2.75 or +3.00D, 76 to 80 : +3.25 or +3.50D, over81 : + 3.75D 여자 : 50 to 60 : +1.25 or +1.50D, 61 to 65 : +1.75 or +2,00D, 66 to 70 : +2.25 or +2.50D 71 to 75 : +2.25 or +2.50D, 76 to 80 : +2.75 or +3.00D, over81 : +2.75 or +3.00D 4. 돋보기를 착용한 상태에서 작업시간은 대체적으로 1~2시간 사용이 않았으나 5시간 이상 사용자도 있었다. 5. 도시와 섬마을 노안에서 대부분 백내장, 군날개, 고혈압, 당뇨, 녹내장이 있는 것으로 조사되었다.
