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
Neurosurgery
Surgical Oncology

Background:

Orbital cavernous hemangiomas, particularly retrobulbar ones, pose surgical challenges.
Existing surgical techniques for these tumors can be traumatic.
Minimally invasive approaches are sought for functional and cosmetic preservation.

Purpose of the Study:

To evaluate the efficacy of the transconjunctival approach for orbital cavernous hemangiomas.
To analyze the clinical and radiologic features of these tumors in relation to treatment outcomes.

Main Methods:

A transconjunctival orbitotomy was performed on 39 patients with orbital cavernous hemangiomas.
Clinical and radiologic data were collected and analyzed.

Main Results:

Computed tomography and magnetic resonance imaging identified well-defined intraconal masses.
Tumor removal was successful in 37 cases; 1 patient had vision loss.
Visual acuity improved in 6/9 cases with impairment; proptosis resolved in 32 patients.

Conclusions:

The transconjunctival approach is effective for retrobulbar intraconal cavernous hemangiomas.
Consider alternative surgical routes for tumors near the orbital apex or with complex vascularity.
