| 설명 | 녹내장이란 안구방수로 차있는 공간인 앞방과 뒤방의 압력이 높아지는 것을 이르는 말이다. 이 녹내장은 안구방수가 너무 많이 생기거나 안구방수의 흡수의 길이 박혀서 생긴다. 즉 전방과 후방에 안구방수의 저류에 의해서 그곳의 압력이 높아지는 것을 말한다. 지속적인 안압의 상승은 눈에 나쁜 영향을 준다. 특히 시야의 변화를 일으키는데 이것은 주로 안압의 상승으로 인해서 시신경이 눌려서 생긴다. 특징적인 시야의 변화는 중심시야는 괜찮지만 중심에서 약간 벗어난 곳에 시각의 소실이 생기며 심한 경우에는 시력을 잃기도 한다. 그리고 급격히 안압이 상승할 경우에는 오심, 구토, 충혈 등의 증상과 시력의 소실 등이 나타날 수 있다. 녹내장은 홍채와 각막이 이루는 각도를 기준으로 광우각녹내장(open angle glaucoma)과 협우각녹내장(angle close glaucoma)으로 나눈다. 1.광우각녹내장-홍채와 각막이 이루는 각인 우각이 큰 녹내장을 말한다. 주로 선행하는 안병없이 안압상승으로 인해 장애를 초래하는 병이다. 주로 양안성으로 진행하며 말기까지 어떤 자각증상없이 서서히 진행하는 것이 보통이다. 말기까지 시력장애를 포함한 자각증상이 거의 없으므로 종종 뒤늦게 발견되는 경우가 있다. 2.폐쇄우각녹내장-후방의 압력의 갑작스런 상승으로 홍채가 전방 이동과 함께 우각이 폐쇄되어 발생한다. 홍채와 각막사이에는 안구방수가 정맥으로 나가는 길인 슐렘구멍이 있고 만약 홍채와 각막이 이루는 각이 적어질 경우에 이 슐렘구멍 폐쇄가 되어서 갑작스런 안압의 상승을 초래한다. 48시간 이내에 안압을 조절하지 않으면 때로는 영구적 실명을 일으키게 된다. 어떤 유발요인의 작용으로 갑작스런 발작이 일어나면 심한 안통 또는 두통을 수반한 시력상실을 일으킨다. 오심 또는 구토, 그리고 충혈 등의 증세가 동반이 된다. |

| absolute | 1. Loosed from any limitation or condition; uncontrolled; unrestricted; unconditional; as, absolute authority, monarchy, sovereignty, an absolute promise or command; absolute power; an absolute monarch. 2. Complete in itself; perfect; consummate; faultless; as, absolute perfection; absolute beauty. "So absolute she seems, And in herself complete." (Milton) 3. Viewed apart from modifying influences or without comparison with other objects; actual; real; opposed to relative and comparative; as, absolute motion; absolute time or space. Absolute rights and duties are such as pertain to man in a state of nature as contradistinguished from relative rights and duties, or such as pertain to him in his social relations. 4. Loosed from, or unconnected by, dependence on any other being; self-existent; self-sufficing. In this sense God is called the Absolute by the Theist. The term is also applied by the Pantheist to the universe, or the total of all existence, as only capable of relations in its parts to each other and to the whole, and as dependent for its existence and its phenomena on its mutually depending forces and their laws. 5. Capable of being thought or conceived by itself alone; unconditioned; non-relative. It is in dispute among philosopher whether the term, in this sense, is not applied to a mere logical fiction or abstraction, or whether the absolute, as thus defined, can be known, as a reality, by the human intellect. "To Cusa we can indeed articulately trace, word and thing, the recent philosophy of the absolute." (Sir W. Hamilton) 6. Positive; clear; certain; not doubtful. "I am absolute 't was very Cloten." (Shak) 7. Authoritative; peremptory. "The peddler stopped, and tapped her on the head, With absolute forefinger, brown and ringed." (Mrs. Browning) 8. <chemistry> Pure; unmixed; as, absolute alcohol. 9. Not immediately dependent on the other parts of the sentence in government; as, the case absolute. See Ablative absolute, under Ablative. <geometry> Absolute curvature, the sum of the optic and eccentric equations. <physics> Absolute space, space considered without relation to material limits or objects. Absolute terms. <mathematics> The be ginning, or zero point, in the scale of absolute temperature. It is equivalent to -273 deg centigrade or -459.4 deg Fahrenheit. Synonym: Positive, peremptory, certain, unconditional, unlimited, unrestricted, unqualified, arbitrary, despotic, autocratic. Origin: L. Absolutus, p. P. Of absolvere: cf. F. Absolu. See Absolve. <geometry> In a plane, the two imaginary circular points at infinity; in space of three dimensions, the imaginary circle at infinity. Source: Websters Dictionary (01 Mar 1998) |

| absolute agraphia | Agraphia in which not even unconnected letters can be written. Synonym: atactic agraphia, literal agraphia. (05 Mar 2000) |
| absolute alcohol | Water having been removed. Synonym: anhydrous alcohol. (05 Mar 2000) |
| absolute CD4 count | The number of helper T-lymphocytes in a cubic millimeter of blood. With HIV, the absolute CD4 count declines as the infection progresses. The absolute CD4 count is frequently used to monitor the extent of immune suppression in persons with HIV. Also called a T4 count. (12 Dec 1998) |
| absolute configuration | <chemistry> The three-dimensional arrangement of the atoms around the chiral centre of a molecule. (09 Oct 1997) |
| absolute dehydration | Actual water deficit as measured by a difference from the normal or from a given water content. (05 Mar 2000) |
| absolute eosinophil count | <haematology, investigation> A measurement (cells per microlitre) of the number of eosinophils in a blood specimen. This measurement is useful in the evaluation of autoimmune disease, allergies, eczema, leukaemia, asthma and hay fever. Normal absolute eosinophil counts are less than 350 cells/mcl (microlitre). (27 Sep 1997) |
| absolute filter | <apparatus> A fine-pored, steam-sterilisable filter that is used to trap airborne microorganisms. The filter's pores are about 2 micrometres in diameter, smaller than the particles it is designed to remove. (06 May 1997) |
| absolute gravity | <chemistry> The value that denotes the density (specific gravity) at standard conditions (for gases, these conditions are standard atmospheric pressure at zero degrees Celsius). (06 May 1997) |
