Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.0K
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

1.1K
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...

Acute Pharyngitis

3.2K
Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

885
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...

Epistaxis01:30

Epistaxis

431
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Chronic Pharyngitis01:23

Chronic Pharyngitis

9.5K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Summary

Primary care providers should consider conjunctivitis as a potential early symptom of COVID-19. Prompt identification of this ocular manifestation aids in early diagnosis and prevents further spread of SARS-CoV-2.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Virology

Background:

  • Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, presents with common symptoms like fever and cough.
  • Ocular manifestations, such as conjunctivitis, are infrequently reported but significant.
  • Early and accurate diagnosis is critical for pandemic management and patient care.

Observation:

  • A case study involving a 54-year-old woman with isolated conjunctivitis is presented.
  • The patient was subsequently diagnosed with COVID-19.
  • Delayed diagnosis was attributed to incomplete travel history, increasing transmission risk.

Findings:

  • Conjunctivitis can be an atypical, sole presenting symptom of COVID-19.
  • Failure to consider ocular symptoms can lead to delayed diagnosis and increased risk to healthcare teams.
  • This case highlights the importance of a high index of suspicion for SARS-CoV-2 in patients with conjunctivitis.

Implications:

  • Primary care practitioners should include COVID-19 in their differential diagnosis for patients presenting with conjunctivitis.
  • Screening for ocular symptoms at entry points can improve early identification of infectious patients.
  • Adherence to safety protocols is paramount when managing patients with potential COVID-19, especially those with atypical presentations.
