Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.7K
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...

Aneurysm III: Interprofessional Care

465
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Glaucoma: Overview01:25

Glaucoma: Overview

1.7K
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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

1.1K
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...

Aneurysm I: Introduction

641
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Area of Science:

  • Neuroendovascular surgery
  • Cerebrovascular diseases
  • Ophthalmic surgery

Background:

  • Ophthalmic segment aneurysms (OSA) treatment using flow-diversion is not extensively studied.
  • Evaluating the efficacy and safety of flow-diversion for OSA is crucial.

Purpose of the Study:

  • To assess visual outcomes, obliteration rates, and retreatment necessity for OSA treated with the Pipeline Embolization Device (PED).

Main Methods:

  • Retrospective review of 41 patients (44 OSA) treated with PED between 2009 and 2014.
  • Data collected included patient demographics, aneurysm characteristics, complication rates, retreatment needs, occlusion rates, and symptom evolution.

Main Results:

  • Complete occlusion was achieved in 77.27% of OSA at final angiographic follow-up.
  • Significant visual symptom improvement was noted in 72.72% of symptomatic OSA.
  • The complication rate was 2.27% with a 0% mortality rate.

Conclusions:

  • Flow-diversion with PED is an appealing option for OSA treatment due to its high obliteration rate.
  • The observed improvement in visual symptoms and low complication rate support its use.
  • Further evaluation of flow-diversion for ophthalmic segment aneurysms is warranted.
