| convergence-retraction nystagmus | Irregular, jerky nystagmus combining convergence and retraction of the eye into the orbit, especially on attempting an upward gaze. Synonym: Koerber-Salus-Elschnig syndrome. (05 Mar 2000) |
| points of convergence | <microscopy> In colour video cameras and monitors, the precise alignment of the images or pictures in the three primary colours (red, green and blue). A lack of convergence gives rise to asymmetrically coloured fringes. (05 Aug 1998) |
| positive convergence | Inward deviation of the visual axes even when convergence is at rest, as in cases of convergent squint. (05 Mar 2000) |
| near point of convergence | The point to which the visual lines are directed when convergence is at its maximum. (05 Mar 2000) |
| negative convergence | The slight divergence of the visual axes when convergence is at rest, as when observing the far point or during sleep. (05 Mar 2000) |
| far point of convergence | The point to which the visual lines are directed when convergence is at rest. (05 Mar 2000) |
| unit of convergence | See: meter angle. (05 Mar 2000) |
| unit of ocular convergence | The amount of convergence required to view binocularly an object 1 meter distant and exerting 1 diopter of accommodation. Synonym: unit of ocular convergence. (05 Mar 2000) |
