| 설명 | 정상적으로 시야(visual field)에서 보이지 않는 부분을 말함. 이것이 생기는 이유는 시신경이 뇌에서 기시하여 안구내를 통해 들어오기 때문이다. 시각은 각막과 렌즈를 통과한 빛이 각막의 시각세포에 닿은 뒤, 시각세포에 의해 시각이 시각신경으로 전해져 형성된다. 이때 시각신경은 안구의 뒤쪽으로 들어와 망막의 한 부분을 차지하게 되어, 시각신경이 존재하는 부분에는 시각세포가 존재할 수 없게 된다. 따라서 이 부위는 시각을 형성할 수 없으며, 정상적으로 까만 보이지 않는 시야를 형성하게 된다. |

| absolute scotoma | A scotoma in which there is no perception of light. (05 Mar 2000) |
|---|---|
| annular scotoma | A circular scotoma surrounding the centre of the field of vision. See: ring scotoma. (05 Mar 2000) |
| arcuate scotoma | A scotoma extending from the blind spot and arching into the nasal field following the lines of retinal nerve fibres. (05 Mar 2000) |
| Bjerrum's scotoma | A comet-shaped scotoma, occurring in glaucoma, attached at the temporal end to the blind spot or separated from it by a narrow gap; the defect widens as it extends above and nasally curves around the fixation spot, and then extends downward to end exactly at the nasal horizontal meridian. Synonym: Bjerrum's sign, sickle scotoma. (05 Mar 2000) |
| caecocentral scotoma | A scotoma involving the optic disk area (blind spot) and the papillomacular fibres; there are three forms: 1) the caecocentral defect which extends from the blind spot toward or into the fixation area; 2) angioscotoma; 3) glaucomatous nerve-fibre bundle scotoma, due to involvement of nerve-fibre bundles at the edge of the optic disk. See: Bjerrum's scotoma, Ronne's nasal step. (05 Mar 2000) |
| paracentral scotoma | A scotoma adjacent to the fixation point. (05 Mar 2000) |
| glaucomatous nerve-fibre bundle scotoma | See: caecocentral scotoma. (05 Mar 2000) |
| relative scotoma | A scotoma in which there is visual depression but not complete loss of light perception. (05 Mar 2000) |
| central scotoma | A scotoma involving the fixation point. (05 Mar 2000) |
| mental scotoma | Absence of insight into, or inability to comprehend, items relative to a subject whose content is highly emotional to the individual. Synonym: blind spot. (05 Mar 2000) |
| pericentral scotoma | A scotoma that surrounds the fixation point more or less symmetrically. (05 Mar 2000) |
| peripheral scotoma | A scotoma outside of the central 30 degrees of the visual field. (05 Mar 2000) |
| ring scotoma | An annular area of blindness in the visual field surrounding the fixation point in pigmentary degeneration of the retina and in glaucoma. (05 Mar 2000) |
| physiologic scotoma | The negative scotoma in the visual field, corresponding to the optic disk. Synonym: blind spot. (05 Mar 2000) |
| colour scotoma | An area of depressed colour vision in the visual field. (05 Mar 2000) |
