Angle Closure Glaucoma: Treatment01:28

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...
Glaucoma: Overview01:25

Glaucoma: Overview

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

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.

Transient Ischemic Attack l: Introduction01:26

Transient Ischemic Attack l: Introduction

A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
Acute Coronary Syndrome I: Introduction01:30

Acute Coronary Syndrome I: Introduction

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Summary

Giant cell arteritis can cause sectoral choroidal ischemia, a rare condition affecting vision. Prompt corticosteroid treatment helped preserve some sight, but long-term outcomes were limited by retinal pigment epithelium changes.

A Murine Model of Ischemic Retinal Injury Induced by Transient Bilateral Common Carotid Artery Occlusion

Published on: November 12, 2020

Area of Science:

  • Ophthalmology
  • Vascular Medicine
  • Rheumatology

Background:

  • Giant cell arteritis (GCA) is a systemic vasculitis often affecting medium and large arteries.
  • While GCA commonly presents with anterior ischemic optic neuropathy or central retinal artery occlusion, sectoral choroidal ischemia is a less frequent but significant manifestation.

Observation:

  • A case report details a 68-year-old, one-eyed patient experiencing acute visual decline and metamorphopsia in his remaining eye.
  • Fundus examination showed retinal pigment epithelium (RPE) alterations, and fluorescein angiography revealed delayed choroidal perfusion.
  • Macular Optical Coherence Tomography (OCT) confirmed complete disruption of the photoreceptor layer.

Findings:

  • The patient presented with acute choroidal ischemia, a rare sign of GCA.
  • Despite immediate corticosteroid therapy, which preserved some visual acuity, the patient's long-term visual outcome was compromised.
  • Secondary macular RPE changes developed, limiting the final visual result.

Implications:

  • This case highlights sectoral choroidal ischemia as a potential, albeit uncommon, presentation of GCA.
  • Early diagnosis and intervention with corticosteroids are crucial for potentially preserving vision in such cases.
  • Understanding the long-term sequelae, such as RPE changes, is important for managing patient expectations and prognosis.
