Glaucoma: Overview01:25

Glaucoma: Overview

1.6K
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

1.1K
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...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.6K
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...

Autoimmune Disorders01:29

Autoimmune Disorders

2.1K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Microbiome of the Eye01:22

Microbiome of the Eye

4
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...

Area of Science:

  • Ophthalmology
  • Immunology
  • Neuroscience

Background:

  • Glaucoma is a common neurodegenerative disease with an immunologic component.
  • Changes in autoantibody concentrations against retinal and optic nerve head antigens are observed in glaucoma patients.
  • Antibody deposits and a pro-inflammatory environment are found in glaucomatous retinae.

Purpose of the Study:

  • To investigate the role of autoantibodies in glaucoma pathogenesis.
  • To explore the dual nature of natural autoantibodies in glaucoma, encompassing both potential harm and neuroprotection.
  • To identify potential diagnostic biomarkers and therapeutic targets based on autoantibody profiles.

Main Methods:

  • Analysis of autoantibody concentrations in glaucoma patients.
  • Examination of antibody deposits in human glaucomatous retinae.
  • Review of clinical studies on autoantibody level regulation.

Main Results:

  • Both up-regulated and down-regulated autoantibody levels are observed in glaucoma.
  • Natural autoantibodies exhibit neuroprotective characteristics and influence neuroretinal cell protein expression.
  • A physiological misbalance may shift immunity towards neuroinflammation, predisposing to glaucoma.

Conclusions:

  • The equilibrium of natural autoimmunity is critical in glaucoma, balancing autoaggression and neuroprotection.
  • Autoantibodies offer promising therapeutic targets for glaucoma.
  • Altered antibody profiles can serve as sensitive and specific biomarkers for glaucoma diagnostics.
