Control of exodeviation will be measured at Home and the Clinic using the revised Newcastle Control Score (NCS) | |
Distance (6 m): fixing on an accommodative target | |
Near (1/3 m): fixing on Lang near-viewing stick or a similar accommodative target | |
The scale below applies to both distance and near separately. | |
Home control | Score |
XT or monocular eye closure seen never | 0 |
< 50% of time fixing at distance | 1 |
> 50% of time fixing at distance | 2 |
> 50% of time fixing at distance + seen at near | 3 |
Clinical control | |
Near | |
Immediate realignment after dissociation | 0 |
Realignment with aid of blinking or re-fixation | 1 |
Remains manifest after dissociation or prolonged fixation | 2 |
Manifest spontaneously | 3 |
Distance | |
Immediate realignment after dissociation | 0 |
Realignment with aid of blinking or re-fixation | 1 |
Remains manifest after dissociation or prolonged fixation | 2 |
Manifest spontaneously | 3 |
Total NCS = home + near+ distance. |
