Angle Closure Glaucoma: Treatment

Angle Closure Glaucoma: Treatment

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...

Open Angle Glaucoma: Treatment

Open Angle Glaucoma: Treatment

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Area of Science:

Ophthalmology
Emergency Medicine
Trauma Surgery

Background:

Blunt ocular trauma can lead to retrobulbar hemorrhage, causing increased orbital pressure.
Rapidly increasing orbital pressure poses a significant risk to vision.
Lateral canthotomy and cantholysis are established emergency procedures.

Purpose of the Study:

To present a case of blunt ocular trauma with retrobulbar hemorrhage managed by lateral canthotomy and cantholysis.
To describe the pathophysiology, indications, contraindications, procedure, and follow-up care for this intervention.

Main Methods:

A case report of a 37-year-old male patient with blunt ocular trauma.
Description of the urgent lateral canthotomy and cantholysis procedure performed.
Review of relevant medical literature regarding the procedure.

Main Results:

The case demonstrates the successful application of lateral canthotomy and cantholysis in a vision-threatening emergency.
The procedure effectively reduced orbital pressure, preserving the patient's vision.

Conclusions:

Lateral canthotomy and cantholysis is a valuable and effective procedure for emergency physicians to manage blunt ocular trauma with retrobulbar hemorrhage.
Prompt surgical intervention is crucial for preventing vision loss in such cases.
