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.

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.

These include blurred vision accompanied by eye pain, which may be severe enough to cause nausea and vomiting. Lights appear to have surrounding auras, and adjusting to different illumination levels becomes difficult. Risk of developing the disease increases with age, and can also affected by ethnic background, previous eye surgery, and the presence of certain other illnesses.

Early diagnosis is the key to successful long-term treatment. Standard eye exams for glasses include simple, painless pressure testing, and can quickly detect unnaturally high readings. Gonioscopy is another diagnostic tool that helps determine the extend of blockage in the angle between cornea and iris. Lateral vision deterioration is tested using perimetry equipment, and there are measurements to determine optic nerve damage.

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.

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 victims of this condition realize how important regular eye exams and early detection really are. Because many patients experience the disease for years without overt symptoms, only a physician can determine the extent and severity of the problem. Current technological advances have made early diagnosis simple, easy, and painless, and help preserve visual acuity as long as possible.
