Glaucoma San Antonio Sufferers Rely On Early Detection And Control

By Etta Bowen


Loss of vision changes every single aspect of life. In past centuries, people who lost their eyesight and had no safety net often ended up begging in order to survive. While that rarely happens today, eye diseases like glaucoma still exact a harsh personal penalty, and can result in blindness if not found and treated in time. Glaucoma San Antonio sufferers combat this optic nerve issue using education and advances in technology.

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 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.

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 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 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.
