Is normal-tension glaucoma serious?
Normal tension glaucoma can cause permanent damage to your optic nerve and result in irreversible vision loss. Schedule an eye exam with an eye doctor to detect any signs of optic nerve damage, before your vision is affected.
Which patient is most at risk of developing normal-tension glaucoma?
Risk factors Being over age 60. Being black, Asian or Hispanic. Having a family history of glaucoma. Having certain medical conditions, such as diabetes, heart disease, high blood pressure and sickle cell anemia.
What is the prognosis for normal-tension glaucoma?
Like any form of glaucoma, NTG may progress to irreversible blindness. The prognosis for visual preservation is good in patients who undergo adequate treatment through IOP reduction. In the CNTGS trial, 65% of patients in the control group with NTG did not progress even without treatment.
Will I go blind from normal-tension glaucoma?
Conclusions: The probability of blindness in eyes with NTG is much lower than previously reported in patients with high-tension glaucoma. Nevertheless, special care should be taken to follow NTG patients, and especially those with worse BCVA and more advanced visual field loss at diagnosis.
Is normal tension glaucoma harder to treat?
In summary, NTG glaucoma can be a difficult disease to treat because options are limited to lowering eye pressure. There are significant research efforts to identify treatments that will protect the optic nerve or have an influence on ocular blood flow.
What can cause normal tension glaucoma?
Chronic low vascular perfusion, Raynaud’s phenomenon, migraine, nocturnal systemic hypotension and over-treated systemic hypertension are the main causes of normal tension glaucoma.
What are the first signs that glaucoma is developing?
What is the First Sign of Glaucoma?
- Loss of peripheral or side vision: This is usually the first sign of glaucoma.
- Seeing halos around lights: If you see rainbow-colored circles around lights or are unusually sensitive to light, it could be a sign of glaucoma.
- Vision loss: Especially if it happens suddenly.
Which type of glaucoma is the most serious?
The most serious type of glaucoma is closed-angle glaucoma, also known as acute angle-closure glaucoma. This is the most serious type because it is considered to be a medical emergency.
Is normal-tension glaucoma harder to treat?
Why do I have normal-tension glaucoma?
What percentage of people with normal tension glaucoma go blind?
“The 20-year incidence of blindness in normal tension glaucoma is 9.9% in 1 eye and 1.5% in both eyes,” he said. How can blindness be avoided? “Achieving a consistent IOP reduction of 20–30% is associated with a 93–96% probability of stable NTG without visual field progression over 15 years of treatment,” he explained.
What is normal glaucoma eye pressure?
Studies done on large populations in the United States indicate that average intraocular pressure is between 15-16 mmHg and about 95% of people have an intraocular pressure between ten and 21.
