====== Intermittent Exotropia Office Control Score ======

<wrap round box>Adapted from [[https://pubmed.ncbi.nlm.nih.gov/16950743/ |Mohoney BG. Holmes JM. An office-based scale for assessing control in intermittent exotropia. Strabismus 2006;14:147-150]]</wrap>

  - Observe the child: 
    * for 30 seconds when fixating at distance object
    * if exotropia noted score will be 5, 4 or 3.  
    * Repeat observation with near fixation target for 30 seconds.  
  - If no deviation noted after observation: 
    * Place occluder over right eye for 10 seconds then observe for exotropia counting the seconds until recovery, repeat by occluding the left eye with distance fixation.  
    * Occlude for another 10 seconds the eye that took the longest to re-fuse and then observe. 
    * Repeat the occlusion process with near fixation. 
  - Record the worst level of control noted for distance and near fixation
  - This test should be done before any dissociation or patching or at least 10 minutes after any dissociation. 
  - If the patient has a micro-esotropia by simultaneous prism and cover test, but exodeviation by alternate cover test, the scale applies to the exodeviation.



|Scale Score | Description|
|5| Constant Exotropia|
|4| Exotropia >50% of the 30 second observation |
|3| Exotropia <50% of the 30 second observation |
|2| No Exotropia unless dissociated and recovers > 5 seconds|
|1| No Exotropia unless dissociated, recovers in 1-5 seconds |
|0| No Exotropia unless dissociated, recovers in < 1 second (phoria) |
