Insights

Coronavirus disease 2019 (COVID-19) can cause bilateral simultaneous central retinal vein occlusion (CRVO). This case highlights the importance of recognizing ocular symptoms associated with COVID-19.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Cardiovascular Medicine

Background:

  • Coronavirus disease 2019 (COVID-19) is associated with various thromboembolic complications.
  • Coagulation abnormalities, including elevated D-dimer and C-reactive protein (CRP), are frequently observed in COVID-19 patients.
  • Central retinal vein occlusion (CRVO) is a serious ocular vascular event.

Observation:

  • A 48-year-old male with hypertension, type 2 diabetes mellitus, and stage 4 chronic kidney disease presented with bilateral blurred vision.
  • Ophthalmological examination confirmed bilateral simultaneous central retinal vein occlusion (CRVO).
  • Optical coherence tomography revealed significant macular edema with intraretinal and subretinal fluid in both eyes.

Findings:

  • Laboratory results showed elevated D-dimer and CRP levels, indicating a hypercoagulable state.
  • Despite normal levels of other hypercoagulability markers, the clinical presentation strongly suggested a COVID-19-related thrombotic event.
  • The patient responded well to intravitreal anti-vascular endothelial growth factor therapy, leading to symptom resolution and improved retinal vascular appearance.

Implications:

  • This case underscores the potential for COVID-19 to trigger severe ocular vascular events like bilateral CRVO.
  • Ophthalmologists and healthcare providers should consider COVID-19 as a potential underlying cause for CRVO, especially in patients with relevant risk factors.
  • Increased awareness of COVID-19-associated ocular manifestations is crucial for timely diagnosis and management, potentially preventing vision loss.

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
