Glaucoma: Overview01:25

Glaucoma: Overview

677
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...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

608
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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

518
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...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

6.2K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

24
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

COPD: Pathogenesis and Clinical Features

427
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Area of Science:

  • Ophthalmology
  • Neurology
  • Infectious Diseases

Background:

  • COVID-19 pandemic caused by SARS-CoV-2 has diverse clinical manifestations.
  • Ocular manifestations, including conjunctivitis, have been reported.
  • Neurotropic potential of SARS-CoV-2 suggests possible neuro-ophthalmological complications.

Purpose of the Study:

  • To investigate optic neuropathies occurring post-COVID-19 infection.
  • To analyze risk factors, demographics, evolution, and clinical forms of these optic neuropathies.
  • To review published literature on COVID-19-associated optic neuropathies from 2020-2022.

Main Methods:

  • Literature search conducted on Google Scholar and PubMed.
  • Selection of 21 cases of optic neuropathy related to COVID-19.
  • Analysis of patient data including age, gender, clinical presentation, and outcomes.

Main Results:

  • 21 patients (11 female, 10 male) with optic neuropathy post-COVID-19 identified.
  • Types of optic neuropathies included retrobulbar optic neuropathy, papillitis, neuroretinitis, and anterior ischemic optic neuropathy (AION).
  • One case of MOG-associated optic neuropathy and one case of arteritic AION were noted; others were non-arteritic AION.

Conclusions:

  • Neuro-ophthalmological complications of COVID-19 can be severe and require continuous monitoring.
  • Comprehensive investigations are needed to rule out other causes of optic neuropathy.
  • A complete ophthalmological examination is essential for all COVID-19 patients, regardless of initial ocular symptoms.
