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:

Neurosurgery
Ophthalmology
Oncology

Background:

Orbital cavernous hemangiomas (venous malformations) are common intraorbital tumors, often requiring surgery for symptomatic relief.
Transcranial and lateral orbitotomy approaches are traditional surgical methods for these tumors.

Observation:

A 62-year-old male presented with progressive proptosis and visual impairment due to a large superolateral intraconal cavernous hemangioma.
MRI confirmed the tumor compressing the optic nerve.

Findings:

A one-piece modified orbitozygomatic approach enabled complete tumor resection.
Postoperative outcomes included proptosis resolution, improved eye movement, and better visual acuity.

Implications:

The orbitozygomatic approach provides excellent surgical access and visualization for large orbital cavernous hemangiomas.
This technique facilitates safe tumor dissection and satisfactory orbital decompression.
