| 설명 | 빛의 수용기로서, 두께 0.5~1mm의 그물모양구조를 이루며, 눈알의 신경부에 해당한다. 외측에 색소상피층, 시각세포(원뿔세포, 막대세포)의 층, 쌍극세포층, 신경절세포층, 가장 안쪽에는 신경섬유층이 있다. 눈에 들어온 빛은 신경섬유층, 신경절세포층, 쌍극세포층을 통과해 시각세포에 도달하며, 이곳에서 감광색소와 광화학적변화를 일으킨다. 이 변화를 쌍극세포로 전달하고 다시 중추로 전달하여 빛으로 감각된다. 망막의 부위에 따라 시각세포 분포가 달라, 황반이라고 불리는 부위에서는 원뿔세포만이 존재하며, 그 주위는 막대체세포가 많다. 시각신경이 들어오는 부위인 유두부에는 시각세포가 결여되어, 빛을 느끼지 않는다. 이것이 맹점이다. 망막 후부의 중앙에는 가장 예민한 황반이 있고, 황반의 중앙에는 막대시각세포가 없는 중심오목이 있다. 중심오목과 안쪽 약 0.25cm에는 시각신경 및 망막중심동맥이 들어가는 점이 있다. 이곳에서 망막은 불완전하며 맹점을 형성한다. |

| giant pigmented nevus | These large pigmented (often hairy) congenital nevi are important because of their increased risk (10 to 15%) of conversion into malignant melanoma. A biopsy can confirm if cells have turned malignant. Any change in a pre-existing nevus should prompt a physician evaluation. (27 Sep 1997) |
| villonodular pigmented tenosynovitis | A condition resembling pigmented villonodular synovitis but arising in periarticular soft tissue rather than in joint synovia; occurs most commonly in the hands. Synonym: villonodular pigmented tenosynovitis. (05 Mar 2000) |

| pigmented ameloblastoma | 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) |
| pigmented dermatofibrosarcoma protuberans | An uncommon variant of dermatofibrosarcoma protuberans containing heavily pigmented dendritic melanocytes scattered between spindle cells of the tumour. Synonym: Bednar tumour, storiform neurofibroma. (05 Mar 2000) |
| pigmented epulis | 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) |
| pigmented hair epidermal nevus | A nevus first seen as an irregular pigmentation of the shoulders, upper chest, or scapular area, gradually enlarging irregularly and becoming thickened and hairy. Synonym: pigmented hair epidermal nevus. (05 Mar 2000) |
| pigmented keratic precipitates | Precipitate's that occur in eyes with brown irides or after prolonged inflammation. (05 Mar 2000) |
| pigmented layer of ciliary body | The continuation of the pigment layer of the retina onto the posterior aspect of the ciliary body. Synonym: pigmented layer of ciliary body. (05 Mar 2000) |
| pigmented layer of iris | The double layer of pigmented epithelium on the posterior surface of the iris. Synonym: pigmented layer of iris. (05 Mar 2000) |
| pigmented liver | A liver that contains pigment, such as occurs in Dubin-Johnson syndrome, haemochromatosis, long-standing malaria. (05 Mar 2000) |
| pigmented purpuric lichenoid dermatosis | An eruption comprised of lichenoid papules variously pigmented from the haemosiderin of the associated purpura; found on the legs, usually in men over 40 years of age. Synonym: Gougerot and Blum disease. (05 Mar 2000) |
