Glaucoma San Antonio Sufferers Rely On Early Detection And Control

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.

Glaucoma commonly attacks both eyes, and is characterized by ever-increasing liquid pressure within those orbs. Fluids regularly drain under normal circumstances, which allows internal pressure to remain balanced. If that natural process is blocked, internal forces slowly build, often causing permanent damage to nearby ocular structures, including the optic nerve. The two most common types are called open and closed angle.

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.

These signs of trouble include eye pain that may be harsh enough to cause vomiting and nausea. Electric lights may seem to have glowing auras, and adjusting to light intensity changes in different environments becomes harder. Age increases the chances of developing this problem, which can also be encouraged by genetic inheritance, the presence of other illnesses, and even recent eye surgery.

The key to successful treatment is early diagnosis. Pressure tests have become a standard part of most eye exams, and can immediately detect dangerously high levels. Additional tools include gonioscopy, a procedure determining blockage of the angle between the iris and cornea. Perimetry tests can tell whether portions of lateral vision are missing, and optic nerve tools reveal the extent of damage at the rear of the eye.

If problems are discovered during an exam, treatment usually begins as soon as possible. As of yet there is no total cure for this type of complex eye degeneration, but progress can be slowed or even halted. While existing destruction is irreversible, there are significantly helpful eye drops that contain effective drugs, including beta blockers, fluid inhibitors, prostaglandin analogues, and chemicals that stimulate liquid flow.

If medication delivered via drops proves ineffective, surgery may relieve the pressure. Drainage passages are being unblocked today by skilled laser surgeons, and patients are benefiting from other methods designed to reduce interior forces manually. In some cases, an aqueous shunt is installed. A victim of acute-angle disease may be treated as an emergency, requiring immediate drug treatment or surgery to preserve vision.

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.
