Glaucoma: Overview01:25

Glaucoma: Overview

621
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

479
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...

Genome-wide Association Studies-GWAS

13.6K
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...

Human Genetics

612
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

560
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...

Area of Science:

  • Ophthalmology
  • Genetics
  • Public Health

Background:

  • Glaucoma is a leading cause of irreversible blindness and is highly heritable.
  • The majority of glaucoma risk genes remain unidentified.
  • Genetic prediction of glaucoma risk and treatment response requires further research.

Purpose of the Study:

  • To identify novel disease genes for glaucoma.
  • To enhance genetic prediction models for glaucoma risk.
  • To improve understanding of treatment response in glaucoma patients.

Main Methods:

  • Established the Genetics of Glaucoma Study (GOGS) with over 5700 participants.
  • Collected questionnaire data on medical history, glaucoma status, and treatments.
  • Obtained DNA samples and consented to data linkage with Australian Government health records.

Main Results:

  • Recruited over 5700 participants, one of the largest glaucoma genetic studies globally.
  • Detailed clinical and genetic data collected, including medication use and surgical history.
  • Identified common comorbidities such as ocular hypertension, cataracts, and hypertension.

Conclusions:

  • GOGS is a significant resource for global glaucoma gene-mapping efforts.
  • The study will facilitate the development of genetic risk prediction models.
  • GOGS will investigate genetic overlaps and causal relationships with glaucoma comorbidities.
