-  * Observe the child for 30 seconds when fixating at distance and then again when fixing at near object  +  - Observe the child:  
-  * If no deviation noted place occluder over right eye for 10 seconds, repeat by occluding the left eye with distance fixation.   +    * for 30 seconds when fixating at distance object 
-    * Occlude for another 10 seconds the eye that took the longest to re-fuse.  +    * if exotropia noted score will be 5, 4 or 3.   
-    * Repeat with near fixation.  +    * Repeat observation with near fixation target for 30 seconds.   
-  * Record the worst level of control noted +  - If no deviation noted after observation:  
-  * This test should be done before any dissociation or patching or at least 10 minutes after any dissociation. +    * 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.
