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...

Open Angle Glaucoma: Treatment

869
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...

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...

Photoreceptors and Visual Pathways

8.3K
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,...

Skin Diseases and Disorders

5.0K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Summary

Adult vernal keratoconjunctivitis (VKC) is an uncommon, chronic allergic eye disease. Adult VKC variants present with heightened inflammation and a greater risk of vision-threatening fibrotic complications.

Area of Science:

  • Ophthalmology
  • Allergology
  • Immunology

Background:

  • Vernal keratoconjunctivitis (VKC) is a rare, chronic allergic eye condition typically affecting children.
  • Recent literature describes adult VKC, with early-onset (childhood VKC persisting) and late-onset (de novo adult onset) variants.
  • While adult VKC patients are a small subset, detailed analysis is lacking.

Purpose of the Study:

  • To review the pathogenesis, clinical features, diagnosis, and treatment of adult VKC.
  • To highlight recent advancements in understanding this specific VKC subtype.
  • To explore the role of sex hormones and inflammation/fibrosis mechanisms in adult VKC.

Main Methods:

  • Literature review of existing studies on adult VKC.
  • Analysis of clinical manifestations and inflammatory responses.
  • Examination of diagnostic and therapeutic alternatives.

Main Results:

  • Adult VKC shares manifestations with classic VKC but exhibits a more intense inflammatory response.
  • Adult VKC carries an increased risk of chronic fibrotic sequelae.
  • Research into adult VKC may illuminate sex hormone impacts on allergies and fibrosis mechanisms.

Conclusions:

  • Adult VKC is a distinct clinical entity with potentially severe outcomes.
  • Understanding adult VKC is crucial for managing this debilitating condition.
  • Further research is warranted to elucidate the specific mechanisms and optimize treatment for adult VKC.
