|June 14, 2021
Summary
Visual snow, a persistent visual disturbance, may be triggered by coronavirus disease (COVID-19). This neurological condition can manifest with ocular inflammation and long-term visual snow symptoms post-infection.
Area of Science:
- Neurology
- Ophthalmology
- Infectious Disease
Background:
- Visual snow (VS) is a neurological disorder characterized by continuous visual static.
- Diagnosis of VS requires excluding other neurological and ophthalmologic conditions.
- The link between viral infections and neurological symptoms is an area of ongoing research.
Observation:
- A case study describes a patient experiencing visual snow-like symptoms after contracting COVID-19.
- The patient exhibited transient ocular inflammation, including vitreous reaction and optic nerve edema.
- These inflammatory signs resolved, but the visual snow symptoms persisted.
Findings:
- The study suggests COVID-19 may trigger a temporary autoimmune response in susceptible individuals.
- This autoimmune response can lead to ocular inflammation and persistent visual snow.
- This represents the first reported instance of visual snow-like symptoms following COVID-19 infection.
Implications:
- Findings may enhance understanding of COVID-19 complications and neurological sequelae.
- This research could inform new treatment strategies for post-COVID-19 visual disturbances.
- The study opens avenues for investigating autoimmune mechanisms in visual snow pathogenesis.

01:25Glaucoma: Overview
1.0K
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...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

01:28Angle Closure Glaucoma: Treatment
906
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...

01:27Open Angle Glaucoma: Treatment
779
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.

01:12Visual Agnosia
519
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

01:22Photoreceptors and Visual Pathways
7.2K
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,...
