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.

It commonly affects both eyes, and is characterized by an increase in fluid pressure within the eye. Under normal conditions, the fluids drain away, allowing pressure to equalize. When that process is interrupted, internal forces slowly build, and can cause long-term damage to the optic nerve and adjacent eye structures. There are two main types of this ailment, designated open or 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.

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.

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.

When an exam reveals existing issues, treatment often begins immediately. Although there are currently no complete cures for this combination of eye conditions, progression can now be dramatically slowed, and often halted. Existing destruction is not reversible, but the most effective medications include eye drops containing beta blockers, fluid inhibitors, prostaglandin analogues, or liquid flow stimulants.

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.

San Antonio TX sufferers know the vital role eye examinations and early detection play in combating this second leading cause of blindness. Because the disease can progress even without symptoms, only an eye specialist can determine whether there is potential trouble. Technological improvements in equipment make an early diagnosis painless and relatively simple, giving doctors better ways to preserve vision longer.
