| 설명 | 각막은 눈앞에 있는 맑고 투명한 조직으로 기능은 이것을 통과한 빛을 꺽이게 하는 일종의 볼록렌즈로서 눈앞에 존재하여 눈으로 들어오는 빛을 망막에 맺히게 하는 기능을 한다. 만약 각막이 정상보다 두터워서 들어오는 빛을 많이 꺽이게 하면 빛의 초점이 망막보다 앞에 있게 되고 그렇게 되면 근시가 된다. 만약 각막이 정상보다 얇아지게 되면 들어온 빛이 적게 꺽여서 초점이 망막보다 뒤에 맺여 원시가 된다. 난시란 각막의 표면이 균일한 볼록렌즈와 같지 못하고 일정치 못한 것을 말한다. 이렇게 되면 눈에 들어온 빛이 일정하게 꺽이는 것이 아니고 들어오는 방향에 따라 달리 꺽이게 되어서 촛점이 한 점에 모이지 않고 망막에 맺힌 물체의 상이 찌그러져 보이게 된다. |

| regular insulin | A rapidly acting form of insulin which is a clear solution and may be administered intravenously as well as subcutaneously; may be mixed with longer acting forms of insulin to extend the duration of effect. Onset of effect occurs in 1/2 to 1 hour, peak effects are observed in 2 to 3 hours, and the duration of effect is about 5 to 7 hours. Synonym: globin insulin. (05 Mar 2000) |
| regular insulin injection | A preparation that may contain 20, 40, 80, 100, or 500 USP insulin units per ml, although the trend is toward standardizing all insulin preparations at 100 units per ml; it is administered subcutaneously, occasionally intravenously, and has a rapid onset of action, has a brief duration (5 to 7 hours), and is compatible for mixing with long-acting insulin preparations; used in the treatment of diabetic acidosis and insulin coma. Synonym: regular insulin injection. (05 Mar 2000) |

| astigmatism | <ophthalmology> A visual disturbance caused by an error in the refraction of light within the eye. (27 Sep 1997) |
| astigmatism against the rule | Astigmatism when the greater curvature or refractive power is in the horizontal meridian. (05 Mar 2000) |
| astigmatism of oblique pencils | An aberration occurring when a bundle of light rays strikes a refracting medium in some other direction than parallel to the axis of the lens. (05 Mar 2000) |
| astigmatism with the rule | Astigmatism when the greater curvature or refractive power is in the vertical meridian. (05 Mar 2000) |
| mixed astigmatism | Astigmatism in which one meridian is hyperopic while the one at right angle to it is myopic. (05 Mar 2000) |
| compound hyperopic astigmatism | Astigmatism in which all meridians are hyperopic but to different degrees. (05 Mar 2000) |
| compound myopic astigmatism | Astigmatism in which all meridians are myopic but to different degrees. (05 Mar 2000) |
| corneal astigmatism | Astigmatism due to a defect in the curvature of the corneal surface. (05 Mar 2000) |
| myopic astigmatism | That form of astigmatism in which one meridian is myopic and the one at right angle to it is without refractive error. Synonym: simple myopic astigmatism. (05 Mar 2000) |
| hyperopic astigmatism | That form of astigmatism in which one meridian is hyperopic and the one at right angle to it is without a refractive error. Synonym: simple hyperopic astigmatism. (05 Mar 2000) |
| simple hyperopic astigmatism | That form of astigmatism in which one meridian is hyperopic and the one at right angle to it is without a refractive error. Synonym: simple hyperopic astigmatism. (05 Mar 2000) |
| regular astigmatism |
A refractive error caused by an irregular shape of the cornea (usually a football shape) in which the curvature is symmetrical across one or more meridians or axes.
