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.

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.

Victims may not be aware of a developing problem because the symptoms of open angle glaucoma have a gradual onset. Over time, nerve damage results in a loss of peripheral vision that may go unnoticed for years. In the later stages, all vision is affected, and restricted to a narrow, tunnel-like space directly in front. The closed-angle variety causes more immediate problems, and has more noticeable symptoms.

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.

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.

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.

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.
