Glaucoma: Overview01:25

Glaucoma: Overview

570
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

449
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

498
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...

Genome-wide Association Studies-GWAS

13.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Gastritis-II: Pathophysiology

326
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Accessory Structures of the Eye01:17

Accessory Structures of the Eye

1.6K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Area of Science:

  • Rheumatology
  • Ophthalmology
  • Inflammatory Diseases

Background:

  • Gout, a common inflammatory arthritis, is increasingly associated with dry eye symptoms.
  • The precise relationship between gout and dry eye disease remains unclear, prompting further investigation.
  • Understanding this link is vital for managing gout complications and improving patient outcomes.

Purpose of the Study:

  • To review recent literature on the correlation between gout and dry eye disease.
  • To explore the potential pathogenetic mechanisms linking gout and dry eye.
  • To identify factors influencing the co-occurrence of these conditions.

Main Methods:

  • A comprehensive literature search was performed using the PubMed database.
  • The search focused on studies published within the last five years.
  • Information was synthesized to understand the correlation and pathogenesis.

Main Results:

  • Recent studies confirm a correlation between gout and an increased risk of dry eye.
  • The NLRP3-IL-1β signaling pathway is a potential shared mechanism.
  • High uric acid and xanthine oxidase activity in gout may worsen dry eye.

Conclusions:

  • Dry eye manifestations significantly affect the quality of life for gout patients.
  • Early detection and prompt treatment of dry eye are essential in gout management.
  • Lifestyle modifications like reduced screen time and moderated alcohol/coffee intake may be preventative.
