Survival Tips!
-
​Evaluations of extraocular movement and eye alignment are critical survival skills. Abnormalities can be a sign of serious, and occasionally life-threatening pathology.​
​
-
Limited extraocular movement is an indicator of orbital disease.
​
-
The rectus muscles form the boundary of the intraconal space, the cone-shaped area behind the eye.
​​
Emergency Care To Note
-
Disease processes that affect the orbital apex or intraconal space tend to be the most sight-threatening.
