Glaucoma San Antonio Sufferers Rely On Early Detection And Control

By Etta Bowen


Loss of eyesight impacts every single aspect of daily life. In past eras, those who went blind without benefit of social safety nets often ended life as beggars. While that is usually no longer the case, diseases like glaucoma still exact a severe personal toll, and still can result in visual impairment if not found and treated in the early stages. Glaucoma San Antonio patients continue fighting this scourge using medical advances and education.

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.

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. 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.

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.
