|---|---|---|---|
| 설명 | 카메라에 있어서 필름에 해당하는 눈의 망막은 크게 두 개의 층으로 나눌 수가 있다. 안쪽에 있는 실제의 빛을 감지하는 감각층과 바깥쪽의 외부의 빛을 차단하는 색소상피층이 그것인데 그 사이에는 잠재적인 공간이 있어서 떨어지기가 쉽다. 이 사이가 떨어지면 망막의 감각층이 망막의 색소상피층과 분리되는데 이것을 망막박리라고 한다. 이 망막의 박리에는 여러 가지 원인이 있지만 감각층의 망막에 작은 구멍인 열공(break)에 의해서 그곳으로 눈속을 채우고 있는 액체가 흘러 들어가서 생기는 망막의 박리를 열공성 망막박리(rhegmatogenous retinal detachment)라 하고, 안구의 병터에 의해서 안구내에 섬유조직이 생기고 그것이 망막의 감각층을 잡아 끌어서 망막이 박리되는 견인성 망막박리(traction retinal detachment) 및 망막의 2개의 층에 삼출액이 괴어서 생기는 삼출성 망막박리(exudative retinal detachment) 등 열공에 의해서 생기는 망막박리가 아닌 것을 비열공성 망막박리(nonrhegmatogenous retinal detachment)라고 말한다. |

|---|---|---|---|
| 설명 | 혈액의 모든 성분(특히 적혈구)이 혈관계의 밖으로 나오는 것. 종류와 원인은 다음과 같은 것이 있다. ① 파열성 출혈(외상으로 정상인 혈관벽이 파열되었을 때 또는 동맥경화증, 동맥자루나 정맥자루와 같이 혈관벽이 파열되기 쉬운 병터가 있을 경우에 특별히 외력이 작용하지 않아도 혈압의 항진에 따라서 혈관이 파열됐을 때 혈액의 유출을 본다). ② 누출성출혈(혈관벽에 뚜렷한 파열이 없이 비타민 C 결핍<괴혈병>, 세균성독소의 작용 등으로 모세혈관이나 세정맥의 혈관투과성이 항진되어 그 결과로 출혈한다). 또한 혈액이 체외로 유출되는 경우를 외출혈이라 하고 조직내나 체강내로 나오는 경우른 내출혈이라고 한다. 소출혈반은 그 크기에 의하여 점출혈, 자색반(purpura), 반출혈(ecchymoses) 등으로 분류된다. 조직내 대량의 혈액 저류는 혈종(hematoma) 이라고 부른다. |

| hemorrhage | <physiology> The escape of blood from the vessels, bleeding. Small haemorrhages are classified according to size as petechiae (very small), purpura (up to 1 cm) and ecchymoses (larger). The massive accumulation of blood within a tissue is called a haematoma. Origin: Gr. Rhegnynai = to burst forth (18 Nov 1997) |

| all-trans-retinal | The orange retinaldehyde resulting from the action of light on the rhodopsin of the retina, which converts the 11-cis-retinal component of the rhodopsin to all-trans-retinal plus opsin. Synonym: trans-retinal, visual yellow. (05 Mar 2000) |
| blood-retinal barrier | Specialised nonfenestrated tightly-joined endothelial cells that form a transport barrier for certain substances between the retinal capillaries and the retinal tissue. (12 Dec 1998) |
| central retinal artery occlusion | <ophthalmology> The sudden blockage of the retinal artery with a blood clot that commonly leads to a painless but irreversible blindness in that eye. (12 Jan 1998) |
| central retinal fovea | A depression in the centre of the macula retinae containing only cones and lacking blood vessels. Synonym: fovea centralis retinae, central pit. (05 Mar 2000) |
| central retinal vein occlusion | <ophthalmology> The sudden blockage of the retinal vein with blood clot that commonly leads to a painless irreversible blindness in that eye. (12 Jan 1998) |
| retinal | 1. <anatomy> Pertaining to the retina. 2. <biochemistry> The aldehyde of retinol, derived by the oxidative enzymatic splitting of absorbed dietary carotene and having vitamin A activity. In the retina, retinal combines with opsins to form visual pigments. One isomer, 11 cis retinal combines with opsin in the rods (scotopsin) to form rhodopsin or visual purple. Another, all trans retinal (trans r.), visual yellow, xanthopsin) results from the bleaching of rhodopsin by light, in which the 11 cis form is converted to the all trans form. Retinal also combines with opsins in the cones (photopsins) to form the three pigments responsible for colour vision. (18 Nov 1997) |
| retinal adaptation | Adjustment to degree of illumination. (05 Mar 2000) |
| retinal anlage tumour | A benign neoplasm of neuroectodermal origin that most often involves the anterior maxilla of infants in the first year of life. It presents clinically as a rapidly growing blue-black lesion producing a destructive radiolucency; histologically, it is characterised by small round undifferentiated tumour cells interspersed with larger polyhedral melanin-producing cells arranged in an alveolar configuration. Synonym: melanoameloblastoma, pigmented ameloblastoma, pigmented epulis, progonoma of jaw, retinal anlage tumour. (05 Mar 2000) |
| retinal artery | <anatomy, artery> Central retinal artery and its branches. It arises from the ophthalmic artery, pierces the optic nerve and runs through its centre, enters the eye through the porus opticus and branches to supply the retina. (12 Dec 1998) |
| retinal artery occlusion | Occlusion or closure of the central retinal artery causing sudden, usually nearly complete, loss of vision in one eye. Occlusion of the branch retinal artery causes sudden visual loss in only a portion of the visual field. (12 Dec 1998) |
| retinal blood vessels | The blood vasculature of the retina, including the branches and tributaries of the central retinal artery and vein, respectively, and the vascular circle of the optic nerve. Synonym: vasa sanguinea retinae. (05 Mar 2000) |
| retinal camera | An instrument for photographing the ocular fundus. (05 Mar 2000) |
| retinal cone | <ophthalmology, physiology> One of the two photoreceptor cell types in the vertebrate retina. In cones the photopigment is in invaginations of the cell membrane of the outer segment. Cones are less sensitive to light than rods, and are differentially sensitive to particular wavelengths of light and therefore important for colour vision. They provide vision with higher spatial and temporal acuity, and it is the combination of signals from cones with different pigments that facilitates colour vision. There are three types of cones, each type sensitive to red, green or blue. Present in large numbers in the fovea. (03 Jul 1999) |
| retinal degeneration | <ophthalmology> A retrogressive pathological change in the retina, focal or generalised, caused by genetic defects, inflammation, trauma, vascular disease, or aging. Degeneration affecting predominantly the macula lutea of the retina is macular degeneration. (03 Jul 1999) |
