Glaucoma San Antonio Patients Fight To Preserve Vision

By Etta Bowen


Losing the sense of sight changes every aspect of living. In the past, people who developed blindness and had no safety net often ended up homeless, relying on begging for survival. While that happens far less commonly today, conditions like glaucoma still take a severe personal toll, and can result in blindness if not discovered and treated early. Glaucoma San Antonio patients fight optic nerve damage with education and the latest medical advances.

The disease is a combination of conditions that often afflicts both eyes, and is commonly characterized by an internal increase in fluids and pressure. Under normal circumstances those liquids drain, equalizing the pressure. If that process is blocked, internal fluid builds, placing damaging pressure on nearby ocular structures including the optic nerve. There are two primary forms, closed and open angle glaucoma.

Because the onset of symptoms is gradual, victims may be completely unaware they face danger. Over a period of years, nerve damage causes a loss of peripheral vision that may not be obvious. If untreated, later stages affect all types of vision, sometimes restricting it to a small, tunnel-shaped space directly in front of the eyes. Closed angle disease causes more acute symptoms that become immediately noticeable.

Those signs include eye pain accompanied by blurred images, sometimes causing nausea and vomiting. Lights seem surrounded by halos, and adjusting to different illumination levels becomes difficult. Advancing age increases the probability of developing this disease, which can also affect people with specific genetic backgrounds, those who have had recent eye surgery, and people already dealing with other illnesses.

Early diagnosis is the key to successful long-term treatment. Most eye examinations include standard pressure tests which can immediately reveal higher-than-normal pressure levels. Gonioscopy is an additional procedure helpful in determining the extent of blockage of the angle from cornea to iris. Lateral vision loss is detected by perimetry testing, and additional medical tools can determine the amount of damage to the optic nerve itself.

If an exam has uncovered problems, it is vital that treatment begin as soon as possible. While no form of this degenerative condition can be completely cured, progression can be slowed or halted. Even though damage cannot be reversed, the most common therapy includes eye-drops containing prostaglandin analogues, beta blockers, fluid inhibitors, or drugs to stimulate flow.

In some cases, the drops may not prove effective, requiring surgery to relive pressure. Lasers are increasingly being used to unblock drainage passages, and some patients benefit from filtering procedures intended to relieve pressure manually. Some patients receive an aqueous shunt implant. Victims of acute-angle glaucoma are treated as emergencies cases, and require immediate pressure reducing drugs in combination with surgery.

Sufferers in San Antonio TX realize the importance of testing and treatment to combat the progression of this vision-robbing condition. Because there may be no apparent symptoms, only a vision specialist can detect the first signs of trouble. Technological advances in visual medicine have made detection simple and pain-free. Early diagnosis reduces the chance that long-term problems will develop.
