Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

535
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

712
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...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

639
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...

Pericarditis I: Introduction01:22

Pericarditis I: Introduction

18
Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...

Nephrotic Syndrome I : Introduction01:24

Nephrotic Syndrome I : Introduction

22
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...

Area of Science:

  • Ophthalmology
  • Rheumatology
  • Immunology

Background:

  • Ocular sarcoidosis (OS) is a multisystem inflammatory disease with diverse ocular manifestations.
  • Understanding its etiopathogenesis, clinical spectrum, and management is critical for patient outcomes.

Purpose of the Study:

  • To review current knowledge on the etiopathogenesis, clinical features, diagnosis, complications, and therapy of ocular sarcoidosis.
  • To analyze data from a large cohort of biopsy-proven ocular sarcoidosis patients.

Main Methods:

  • Retrospective analysis of electronic medical records from 235 patients with biopsy-proven ocular sarcoidosis.
  • Literature review of recent studies on ocular sarcoidosis.

Main Results:

  • Middle-aged females are predominantly affected, often with bilateral ocular involvement.
  • Key ocular manifestations include uveitis (panuveitis, anterior, intermediate), retinal vasculitis, and granulomas.
  • Common complications include cataract, glaucoma, and cystoid macular edema (CME).

Conclusions:

  • Ocular sarcoidosis presents with a wide range of inflammatory eye conditions, primarily uveitis.
  • Effective management involves steroids and immunosuppressants, tailored to disease severity and localization.
  • Early diagnosis and prompt treatment are essential for managing ocular sarcoidosis and preventing complications.
