Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

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

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

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...

Nephrotic Syndrome II : Assessment and Medical Management

IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document any history...
Nephrotic Syndrome I : Introduction01:24

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of fluid...
Changes in Skin Color: Clinical Perspectives01:14

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Area of Science:

  • Ophthalmology
  • Allergology
  • Immunology

Background:

  • Vernal keratoconjunctivitis (VKC) is a bilateral, seasonal allergic eye inflammation characterized by limbal hypertrophy or giant papillae.
  • While often self-limiting, VKC can cause severe, sight-threatening complications and is a significant cause of hospital referral in Africa and Asia.
  • Its exact etiology and pathophysiology remain unclear, though IgE-dependent and IgE-independent mechanisms involving inflammatory cells and mediators are implicated.

Purpose of the Study:

  • To provide an updated review of the epidemiology, immunopathogenesis, and management of VKC.
  • To highlight the limitations of current treatments and explore promising alternatives.

Main Methods:

  • This review synthesizes information from clinical and immunohistochemical studies.
  • It examines identified risk factors including endocrine, genetic, neurogenic, environmental, and socioeconomic elements.

Main Results:

  • VKC involves complex immune mechanisms with various inflammatory cells and mediators.
  • Standard treatments like topical corticosteroids and mast cell stabilizers are often insufficient for severe cases.
  • Alternative non-steroidal immune modulators like ciclosporin A and tacrolimus show promise but require improved tolerance and reduced costs.

Conclusions:

  • Further research is needed to clarify VKC's etiology and pathophysiology.
  • Improved management strategies are essential for controlling severe cases and preventing recurrences.
  • Optimizing novel immunomodulators is crucial for better VKC patient outcomes.
