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.
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.
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.
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.
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.
