overview
Glaucoma comprises a set of eye conditions that harm the optic nerve. The optic nerve sends visual information from your eyes to your brain and is vital for good vision. Optic nerve damage is often related to high pressure in your eyes. But normal eye pressure can cause narrow-angle.
narrow-angle can occur at any age but is more common in the elderly. It is one of the leading causes of blindness in people over 60 years of age.
Many types of narrow-angle have no warning signs. The effect is so gradual that you may not notice any change in vision until the condition progresses.
Ensuring regular eye examinations, which encompass the measurement of eye pressure, is essential. If glaucoma is recognized early, vision loss can be reduced or prevented. If you have narrow-angle, you will need lifelong treatment or monitoring.

Symptoms: The indications of narrow-angle vary based on the specific type and stage of your condition.
narrow-angle
During the initial phases, no symptoms are apparent:
- Gradually, blind spots in your side vision. Side vision is also known as peripheral vision
- In the later stages, you have difficulty seeing things with your central vision
- Acute angle-closure narrow-angle
- Thank you for your welcome
- Acute eye pain
- Nausea or vomiting
- Blurred vision
- Halos or colored rings around lights
- Eye redness
- Normal-tension narrow-angle
- In the early stages there are no symptoms
- Slow, blurred vision
- Later stages, loss of side vision
narrow-angle in children:
- A dull or cloudy eye (in children)
- Enlarged eyelids (infant) Tears without crying (baby)
- Blurred vision
- Nearsightedness that worsens
- Headache
Pigmentary glaucoma
• Halos around lights
Blurred vision with exercise
• Gradually lose side vision
When to see a doctor?
If you experience symptoms suddenly, you may have acute angle-closure narrow-angle. Indications encompass intense headaches and severe eye pain. You need treatment as soon as possible. Go to the emergency room or call an ophthalmologist’s (ophthalmologist) office immediately.
Reasons
Glaucoma occurs when the optic nerve is damaged. As these nerves gradually deteriorate, blind spots form in your vision. For reasons that doctors don’t fully understand, this nerve damage is usually related to increased eye pressure.
High pressure in the eye is caused by the accumulation of fluid that flows inside the eye. This fluid is also known as aqueous humor. It usually drains through a tissue located at the corner where the iris and cornea meet. This tissue is also called trabecular meshwork. The cornea is important for vision because it allows light to enter the eye. When the eye produces too much fluid or the drainage system does not work properly, eye pressure can increase.
Open-angle glaucoma
It is the most common form of narrow-angle. The drainage angle formed by the iris and cornea is open. But other parts of the drainage system do not drain properly. This may result in a gradual elevation of eye pressure over time.
Angle-closure glaucoma
This form of glaucoma arises when the iris experiences swelling, leading to a partial or complete obstruction of the drainage angle. Consequently, fluid circulation within the eye is impeded, causing a rise in pressure. Angle-closure narrow-angle may manifest suddenly or develop gradually.
Normal-tension glaucoma
No one knows the exact reason why the optic nerve is damaged when the eye pressure is normal. The optic nerve may be sensitive or experience reduced blood flow. A constrained blood flow can result from the presence of fatty deposits in the arteries or other factors that hinder proper circulation. The accumulation of fats in the arteries is referred to as atherosclerosis.
Glaucoma in children
A child can be born with narrow-angle or develop it in the first few years of life. Blocked drainage, injury, or an underlying medical condition can cause damage to the optic nerve. glaucoma specialist near me glaucoma specialist near me
Pigmentary glaucoma
In pigmentary narrow-angle, small pigment granules are shed from the iris and block or slow the drainage of fluid from the eye. Activities like jogging sometimes stir up the pigment. This leads to pigment deposits in the tissue located at the corner where the iris and cornea meet. Pressure increases due to grain accumulation. glaucoma specialist near me
narrow-angle tends to run in families. In certain individuals, researchers have pinpointed genes linked to elevated eye pressure and damage to the optic nerve. glaucoma specialist near me
Risk factors
Glaucoma can cause vision loss before you notice any symptoms. Stay mindful of these potential risk factors:
- Elevated pressure within the eye, commonly referred to as intraocular pressure (IOP).
- Age above 55 years
- Black, Asian or Hispanic heritage
- Family history of narrow-angle
- Specific health conditions, including diabetes, migraines, hypertension, and sickle cell anemia.
- Cornea that is thinner in the center
- Extreme nearsightedness or farsightedness
- Eye injuries or certain types of eye surgery

Some people have a narrow extraction angle, which puts them at risk for angle-closure narrow-angle.
Resistance
These steps can help detect and manage narrow-angle in its early stages. It can help prevent vision loss or slow its progression.
• Get regular eye exams. Routine thorough eye examinations can aid in identifying narrow-angle during its initial phases, preventing substantial damage. As a general rule, the American Academy of Ophthalmology recommends a comprehensive eye exam every 5 to 10 years if you’re under 40; every 2 to 4 years if you are 40 to 54 years old; Every 1 to 3 years if you’re 55 to 64 years old; And every 1 to 2 years if you’re over 65. glaucoma specialist near me.
If you are susceptible to glaucoma, it’s advisable to undergo more frequent screenings. Consult with your healthcare provider to determine the approprdate screening schedule tailored to your needs.
- Know your family’s eye health history. narrow-angle tends to run in families. If you are at risk, you may need more frequent screenings.
- Wear eye protection. Severe eye injuries can lead to narrow-angle. Utilize eye safeguard while operating power tools or engaging in sports activities.
- Take eye drops regularly. narrow-angle eye drops can significantly reduce the risk of high eye pressure progressing to narrow-angle. Use eye drops as prescribed by your healthcare provider even if you have no symptoms. glaucoma specialist near me
