Angle-Closure Glaucoma
Introduction and Overview
Glaucoma is a term used to describe a condition usually characterized by an increase in intraocular pressure (IOP) which damages the tissues in the eye.
Basic Principles of Glaucoma
The eye is filled with fluids which have the function of keeping the structures inside it, the iris, crystalline lens, and retina, in place and nourished. The largest part of the eye, called the posterior chamber , is filled with the vitreous body , a...

Ginkgo Biloba Extract in Glaucoma Treatment
"Ginkgo Biloba Extract (GBE)" has become the subject of study and investigation for its possible use in the treatment of glaucoma. GBE is a freely-available herbal supplement, long known for its positive effect on the functions of the brain, most noticeably in the areas of memory enhancement, mental alertness and the reduction of mental fatigue.
GBE also has many other actions on biological function, such as the improvement of circulation and preventing "vasospasm" , a sudden decrease...

Glaucoma
Glaucoma is a condition usually characterized by increased pressure of the fluid within the eyeball, which causes damage to the retinal nerve fibers and the optic nerve if left untreated. Pressure within the eyeball is measured in mm Hg, the same unit used to describe barometric pressure in weather prediction. The normal range of pressure within the eye is between about 12 mm Hg to 22 mm Hg.
In any discussion about glaucoma, a word that often gets used is “angle.” The fl...

Glaucoma - Open Angle and Closed Angle
One frequently sees the term angle used in reference to glaucoma. In this context angle refers to the eye s internal drainage mechanism.
As mentioned elsewhere a nutrient-rich clear fluid is constantly being produced in the front part of our eyes. The fluid also known as aqueous circulates nourishing the internal tissues before being drained from the eye. The actual drainage opening for the aqueous is formed by the juncture of the cornea and the colorful iris.
This drainage angle in the e...

Glaucoma: Is it Possible to Prevent Vision Loss?
According to a study done in 2004 at The Ohio State University, it might be, for certain individuals in certain circumstances.
Glaucoma is a group of diseases usually characterized by higher than normal pressures within the eye; the increased pressure can compress the retinal nerve fibers, particularly where they come together and form the head of the optic nerve, located in the back of the eye. The most common type of the condition, primary open-angle glaucoma, was the subject of the s...

Heidelberg Retina Tomograph: Better Information, Better Control of Glaucoma
Introduction
Glaucoma is an eye disease most commonly characterized by increased pressure within the eye, known as intraocular pressure (IOP). While increased pressure is one important clinical sign, glaucoma is more complex than a simple measure of pressure.
Instead, it is helpful to consider glaucoma as a disease affecting the optic nerve and all the individual retinal nerve fibers that comprise it.
In the early stages, glaucoma has no symptoms and often goes undiagnosed a...

Hispanic Descent and Serious Eye Disease
People of Hispanic descent have higher risk for serious eye disease, according to a study at the University of Southern California’s Keck School of Medicine, published recently, and the Los Angeles Latino Eye Study (LALES), funded by the US National Eye Institute (NEI).
Serious eye disease, including glaucoma and cataracts, can cause of visual impairment but complications from diabetes and high blood pressure were also found to be significant factors for vision loss.
In additio...

Narrow Angles
“Narrow angle” refers to the shallow space between the cornea at the front of the eye and the coloured iris that lies just behind the cornea. You might be thinking “What does that have to do with anything?” Well the width of the angle is imperative for numerous reasons the most important of which is proper eye functioning.
A nutrient-rich clear fluid is constantly being produced in the front part of our eyes. The fluid also known as aqueous humor circulates and nouris...

OCT - OPTICAL COHERENCE TOMOGRAPHY
This revolutionary test allows doctors an opportunity to better understand and view disease progression of the macula, the retina and the optic nerve long before actual vision loss takes place. Routine analysis of the retina utilizes manual and photographic views of the top layers or simply its surface. OCT tomography provides a more detailed look at the retina with a three-dimensional side-view or optical cross-section.
This procedure provides a more precise analysis of the i...
