Glaucoma San Antonio Patients Fight To Preserve Vision

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.

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.

Because this eye disease progresses slowly, victims may not initially be physically aware of any problem. As time passes, damaged nerves slowly cause losses in peripheral vision, a process that may continue for years. In the final stages, all sight is severely affected and vision restricted to a narrow tunnel directly in front of the face. Closed angle disease can cause immediate problems with very prominent 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.

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.
