Curious about how glaucoma affects your eyes?
Let’s dive in and uncover the details!
Glaucoma is a condition that affects the optic nerve in your eye and worsens over time, often due to increased pressure inside the eye. This pressure, known as intraocular pressure, can harm the optic nerve, which is responsible for sending visual information to your brain. If left untreated, it can lead to permanent vision loss or even blindness within a few years.
Glaucoma often runs in families and typically develops later in life. Early detection and treatment are crucial to protect your vision and slow the progression of the disease.
Glaucoma often develops without any early symptoms or pain, which is why regular visits to your eye doctor are essential. Early diagnosis and treatment can help protect your vision and prevent long-term damage.
Although lost vision cannot be restored, managing eye pressure can help preserve the sight you still have. By staying consistent with your treatment plan and attending regular eye exams, you can significantly reduce the risk of vision loss and maintain your eye health. At Elite Eye Care, we are committed to providing comprehensive care and the latest treatment options to help manage glaucoma and protect your vision.

Primary Types of Glaucoma
Glaucoma primarily comes in two forms:
Open-angle Glaucoma
Out of all the types of glaucoma, open-angle glaucoma is the most common form. In this type, the pressure inside the eye rises gradually, causing slow damage to vision, often starting with peripheral (side) vision. Unfortunately, many people with open-angle glaucoma don't notice any symptoms until their vision is already affected.
Acute Angle Closure Glaucoma
Acute angle-closure glaucoma is a rare but serious form of glaucoma where eye pressure rises suddenly, requiring immediate treatment to prevent permanent vision loss. It’s considered a medical emergency, as optic nerve damage and significant vision loss can occur within hours. Common symptoms include blurred vision, severe eye pain, headaches, halos around lights, nausea, and vomiting. If you experience any of these signs, it’s crucial to contact your ophthalmologist right away.
Secondary Types of Glaucoma:
In addition to the two main types of glaucoma, there are several secondary forms, each with an identifiable cause behind the increased eye pressure. These secondary types of glaucoma include:
Neovascular Glaucoma
Neovascular glaucoma is a rare form of glaucoma that often develops in people with diabetes or other vascular conditions affecting the eye. In this condition, abnormal blood vessels grow over the eye’s drainage channels, blocking the normal outflow of fluid. It can be challenging to manage and often requires care from both a retinal specialist and a glaucoma specialist working together.
Traumatic Glaucoma
Traumatic glaucoma occurs as a result of an eye injury and can develop either immediately after the injury or even years later. It can be triggered by blunt trauma, which bruises the eye, or by penetrating injuries. Certain conditions, such as severe nearsightedness, previous eye trauma, or prior eye surgery, can increase the risk of developing this type of glaucoma.

Childhood Glaucoma
Glaucoma can sometimes affect children, though it is rare. Childhood glaucoma, or juvenile glaucoma, is often linked to heredity and tends to be more challenging to treat. This condition typically requires a collaborative approach, involving both a glaucoma specialist and a pediatric ophthalmologist.
One form of childhood glaucoma, congenital glaucoma, appears shortly after birth or within the first year of life. Unlike other types of childhood glaucoma, congenital glaucoma often presents noticeable symptoms, such as:
- Excessive tearing
- Sensitivity to light
- Cloudy or hazy corneas
Early diagnosis and treatment are essential to protect vision in children with glaucoma.
Let’s uncover the facts about normal tension glaucoma!
Here’s what you need to know about this unique condition
Normal Tension Glaucoma
In normal tension glaucoma, also called low-tension or normal-pressure glaucoma, the optic nerve sustains damage despite having normal intraocular pressure (IOP). Managing and lowering IOP remains crucial, even with this type of glaucoma, to prevent further vision loss.
Wondering how to spot glaucoma early?
Let’s dive into the key symptoms you need to know
What are the symptoms of glaucoma?
In its early stages, glaucoma may not show any symptoms, which is why up to half of those with the condition may not even realize they have it. Often, symptoms don’t appear until the condition has already caused irreversible damage to the optic nerve.
Some common glaucoma symptoms to watch for include:
- Eye pain or pressure
- Headaches
- Red or bloodshot eyes
- Double vision (diplopia)
- Blurred vision
- Gradually worsening low vision
- Gradual development of blind spots (scotomas) or visual field defects like tunnel vision
However, some types of glaucoma, especially Acute angle closure Glaucoma, can cause sudden, severe symptoms that require immediate medical attention to prevent permanent vision loss.
These emergency symptoms include:
- Blood collecting in front of your iris (hyphema)
- Bulging or enlarged eyeballs (buphthalmos)
- Nausea and vomiting that occur with eye pain or pressure
- Rainbow-colored halos around lights
- A sudden increase in floaters (myodesopsias)
- Sudden vision loss of any kind
- Flashing lights appearing suddenly in your vision (photopsias)
Being aware of these symptoms is key to preventing long-term damage and ensuring timely treatment.
What causes Glaucoma?
Glaucoma is a condition that damages the optic nerve, often caused by elevated eye pressure. The condition can develop without a clear cause, but several risk factors are known to influence its onset. A major factor is intraocular pressure (IOP), which results from the buildup of a fluid called aqueous humor in the eye.
Normally, aqueous humor flows through a drainage system in the eye known as the trabecular meshwork. However, in glaucoma, the drainage system becomes less efficient, and the fluid accumulates, raising the pressure inside the eye. Over time, this increased pressure can damage the optic nerve, leading to vision loss.
The causes of fluid buildup vary depending on the type of glaucoma, such as open-angle glaucoma or angle-closure glaucoma, each affecting fluid drainage in different ways.
Personalizing this, if you or someone you know is at risk, it's important to monitor eye health regularly to catch early signs, especially since glaucoma often develops without noticeable symptoms. Regular eye exams are crucial to detect changes in eye pressure and prevent damage to the optic nerve.

Key Glaucoma Treatment Options
Open-angle glaucoma is typically managed through a combination of prescription eye drops, laser treatments like trabeculoplasty, and surgical procedures. While doctors often begin with medications to control eye pressure, laser surgery or microsurgery may be a better first choice for some individuals based on their condition and response to treatment.
Glaucoma Eyedrops: These treatments either reduce the production of fluid in the eye or enhance its drainage, effectively lowering intraocular pressure. However, side effects may include redness, stinging, blurred vision, irritation, and potential allergic reactions. Certain glaucoma medications can also impact the heart and lungs. To avoid complications, it's essential to inform your doctor about any other health conditions or medications you're taking. If you experience difficulty managing multiple eye drops or encounter side effects, your doctor may adjust your treatment plan to better suit your needs.
Oral Medications: Your doctor may recommend oral medications like beta-blockers or carbonic anhydrase inhibitors. These medications help by either reducing the production of fluid in your eye or improving its drainage, effectively lowering intraocular pressure.
Glaucoma Surgery:
- Laser Surgery: If you have open-angle glaucoma, certain procedures can enhance fluid drainage, while for angle-closure glaucoma, these treatments help clear blockages:
- Trabeculoplasty: Improves fluid outflow by opening the eye's drainage system.
- Iridotomy: Creates a small hole in the iris to allow better fluid movement.
- Cyclophotocoagulation: Targets specific areas of the eye to reduce fluid production and lower pressure
These treatments aim to manage eye pressure and protect your vision.
These treatments aim to manage eye pressure and protect your vision.
Microsurgery: During a trabeculectomy, your doctor creates a new drainage channel to lower eye pressure by allowing fluid to escape more effectively. This procedure may need to be repeated if necessary. In some cases, a tube or shunt is implanted to help with fluid drainage. While effective, this surgery carries potential risks such as infection, bleeding, or temporary and, in rare cases, permanent vision changes. Your doctor will discuss these risks and help you decide the best approach based on your condition.
Minimally Invasive Glaucoma Surgeries: This newer, minimally invasive glaucoma surgery (MIGS) involves tiny incisions and devices that are often too small to see with the naked eye. It is generally quicker and safer than traditional surgeries, though it may not reduce eye pressure as significantly. MIGS can also be combined with other procedures like cataract surgery for added convenience and effectiveness.
Acute angle-closure glaucoma, a medical emergency, is typically treated with laser procedures. Immediate medical attention is critical—damage to the optic nerve can begin within hours. If untreated within 6 to 12 hours, this condition may result in severe, permanent vision loss or blindness, along with a permanently enlarged pupil.
For infant or congenital glaucoma, surgery is often necessary because the underlying cause involves a defect in the eye’s drainage system. Early intervention is key to preserving vision and preventing complications.
