Summary
Traumatic asphyxia, a chest compression syndrome, can cause severe eye pressure elevation. Emergency physicians must include prompt ophthalmologic exams in patient secondary surveys.
Area of Science:
- Emergency Medicine
- Ophthalmology
- Trauma Surgery
Background:
- Traumatic asphyxia results from sudden chest pressure increases due to crushing injuries.
- This syndrome commonly presents with thoracic trauma, neurological deficits, and ocular issues.
Observation:
- This case report details traumatic asphyxia complicated by significant, vision-threatening intraocular pressure (IOP) elevation.
- The patient experienced severe ocular hypertension following the initial trauma.
Findings:
- Elevated intraocular pressure is a critical, potentially sight-threatening complication of traumatic asphyxia.
- Prompt tonometry and ophthalmologic evaluation are essential for managing these patients.
Implications:
- Emergency physicians must recognize the risk of elevated intraocular pressure in traumatic asphyxia cases.
- Integrating a thorough ophthalmologic examination into the secondary survey can prevent vision loss.
- Early detection and management of increased IOP are crucial for preserving vision in patients with traumatic asphyxia.

01:25Glaucoma: Overview
919
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

01:28Angle Closure Glaucoma: Treatment
843
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

01:27Open Angle Glaucoma: Treatment
717
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
