Aneurysm I: Introduction01:30

Aneurysm I: Introduction

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...

Aneurysm III: Interprofessional Care

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...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Summary

A young male with vision loss due to miliary Leber aneurysms experienced vision recovery after retinal laser photocoagulation. Treatment successfully resolved macular and peripheral edema, restoring visual acuity.

Area of Science:

  • Ophthalmology
  • Medical Retina

Background:

  • Miliary Leber aneurysms are a rare retinal vascular disorder.
  • Early diagnosis and treatment are crucial for visual prognosis.

Observation:

  • A 21-year-old male presented with unilateral vision decrease.
  • Ophthalmoscopy revealed macular and peripheral retinal edema.
  • Fluorescein angiography demonstrated peripheral retinal telangiectasia, arteriovenous shunts, and hypoperfusion.

Findings:

  • Diagnosis of miliary Leber aneurysms was established based on clinical and angiographic findings.
  • Laser photocoagulation, including macular GRID and peripheral scatter, was performed.
  • Significant improvement in visual acuity and resolution of retinal edema were observed after 4 months.

Implications:

  • Laser photocoagulation is an effective treatment for miliary Leber aneurysms.
  • Prompt intervention can lead to visual recovery in affected patients.
  • This case highlights the importance of comprehensive retinal evaluation for unexplained vision loss.
