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

Background:

Idiopathic intracranial hypertension (IIH) can cause vision loss due to increased intracranial pressure.
Optic nerve sheath fenestration is a surgical procedure to relieve pressure on the optic nerve.

Observation:

A patient with IIH underwent a vertical lid split orbitotomy for optic nerve sheath fenestration.
This approach involved a vertical incision for superomedial orbital access to the optic nerve sheath.

Findings:

The optic nerve sheath fenestration was successfully performed using the vertical lid split approach.
The patient experienced significant improvement in symptoms following the procedure.

Implications:

The vertical lid split orbitotomy offers a minimally invasive method for optic nerve sheath fenestration.
This technique may be a valuable alternative for optic nerve decompression in IIH patients.
