Intravitreal Injection and Quantitation of Infection Parameters in a Mouse Model of Bacterial Endophthalmitis
Published on: February 6, 2021
Summary
Herpes viruses like HSV and VZV commonly cause chronic anterior uveitis. Cytomegalovirus can lead to severe retinitis in immunocompromised individuals, highlighting viral roles in ocular inflammation.
Area of Science:
- Ophthalmology
- Virology
- Immunology
Context:
- Viral infections are a significant cause of intraocular inflammation, particularly uveitis.
- Herpes viruses are frequently implicated in well-defined cases of viral uveitis.
- Distinguishing direct viral causation from association is crucial in diagnosing ocular inflammation.
Purpose:
- To summarize the role of herpes viruses in causing viral uveitis.
- To describe specific viral infections affecting the eye, such as anterior uveitis and retinitis.
- To differentiate between viral presence and association in intraocular inflammation.
Summary:
- Herpes simplex virus (HSV) and varicella-zoster virus (VZV) can induce chronic anterior uveitis, often with distinct clinical signs.
- Cytomegalovirus (CMV) is associated with necrotic, hemorrhagic retinitis, especially in immunosuppressed patients.
- Acute retinal necrosis is also linked to herpes virus family members, underscoring their pathogenic potential in the eye.
Impact:
- Provides a concise overview of viral causes of uveitis and retinitis.
- Emphasizes the importance of identifying specific viruses like HSV, VZV, and CMV in ocular disease.
- Highlights the diagnostic challenge of differentiating direct viral infection from associated inflammation in the eye.

01:25Glaucoma: 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...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:25Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
01:26Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
01:28Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
