Orbital compartment syndrome is rare, especially after drug overdose causing rhabdomyolysis. Prompt treatment is crucial for vision, but prognosis remains poor if delayed.
Area of Science:
- Ophthalmology
- Toxicology
- Emergency Medicine
Background:
- Orbital compartment syndrome (OCS) is a rare but sight-threatening condition.
- Rhabdomyolysis, a skeletal muscle injury, can lead to OCS, particularly after prolonged immobilization or drug overdose.
- Ischemic reperfusion injury exacerbates OCS, complicating treatment and prognosis.
Purpose of the Study:
- To report two rare cases of OCS secondary to rhabdomyolysis following drug overdose.
- To highlight the clinical presentation, management, and outcomes of these unique cases.
- To emphasize the importance of prompt diagnosis and intervention in drug-induced rhabdomyolysis leading to OCS.
Main Methods:
- Case report of two patients presenting with symptoms of OCS after drug overdose (tricyclic antidepressant and opiate).
- Clinical evaluation including ophthalmologic examination and assessment of visual acuity.
- Management involved addressing elevated intraorbital pressure and the underlying cause of rhabdomyolysis.
Main Results:
- Both patients developed OCS with associated rhabdomyolysis after drug overdose.
- Compressive orbital ischemia, extraocular muscle swelling, and rebound hyperperfusion were suspected.
- Despite interventions, visual acuity outcomes were poor in one patient, underscoring the critical nature of timely treatment.
Conclusions:
- OCS secondary to drug-induced rhabdomyolysis is an extremely rare event with potentially devastating visual consequences.
- Early recognition and management of elevated intraorbital pressure and rhabdomyolysis are critical for preserving vision.
- This report adds to the limited literature on OCS caused by rhabdomyolysis, emphasizing the need for heightened clinical suspicion in overdose cases.
