How To Do Lateral Canthotomy
Additional Considerations for Lateral Canthotomy
Speed of diagnosis of orbital compartment syndrome (OCS) and of execution of the canthotomy or cantholysis procedure are important to minimize the duration of retinal ischemia. Ophthalmologic consultation should be requested but should not delay the procedure. Because the diagnosis of OCS is purely clinical, the procedure also should not be delayed for imaging studies. Sterile technique is necessary. This procedure is painful. A conscious, confused, or uncooperative patient may require regional nerve block, sedation, or restraint to prevent motion that could result in damage to the eyeball during the procedure. Children may require general anesthesia in the operating room.
