What Are the Early Signs of Glaucoma?

Glaucoma is an eye condition impacting the optic nerve. As intraocular pressure builds, damage to the optic nerve can occur, leading to permanent vision defects and loss, potentially leading to blindness.  

While glaucoma isn’t typically preventable, early detection is crucial if you want to avoid optic nerve damage and slow the progression of vision loss. By knowing the early signs of glaucoma, you can take action at a critical time, increasing your odds of maintaining as much of your vision as possible.  

Here’s what you need to know about the early signs of glaucoma, as well as when you should see an eye health provider.  

Early Signs of Glaucoma  

Generally, there are a few symptoms that can be early signs of glaucoma. One of the most common ones is the loss of peripheral – or side – vision. Over time, it can lead to a sort of tunnel vision, though the process is often slow and hard to identify right when it begins.  

Halos around light are another symptom of glaucoma. Sensitivity to light is similarly a classic sign. In both of these cases, the issues may be particularly apparent in specific situations, such as driving at night.  

Other forms of vision loss – including a sudden decline in acuity or the visual field – can indicate glaucoma, too. Eye redness and pain could be a symptom of acute glaucoma. Haziness of the cornea is a potential symptom, though it’s usually only present with childhood glaucoma.  

In some cases, unexplained nausea or vomiting may also be related to glaucoma, particularly the acute form. The same goes for headaches and blurry vision.  

When to See an Eye Health Provider  

Ultimately, it’s always wise to see an eye health provider whenever you notice any shifts in the visual field or acuity, as well as symptoms of physical changes in the eye. Glaucoma typically isn’t preventable. However, with proper management, vision loss can be minimized.  

Additionally, some of the early signs of glaucoma are also symptoms of other serious eye conditions. For example, redness and eye pain may indicate an infection and, depending on the type, permanent eye damage can occur with surprising speed. Halos may be a sign of glaucoma, cataracts, retinal detachment, and many other potentially serious conditions, all of which should be assessed quickly to determine if treatment is necessary.  

However, even if you don’t have any of the early signs of glaucoma or symptoms of an eye condition, it’s still wise to see your eye health provider regularly. For most adults, an annual appointment is enough to monitor for vision changes and signs of eye health issues, though some may require more frequent visits if certain risks factors are present or they have an eye condition that requires ongoing treatment and tracking.

Early Glaucoma Detection

Glaucoma is a serious eye condition where fluid builds up in the eye, causing damage to the optic nerve. If not treated promptly, glaucoma can cause permanent vision loss, if not total blindness. That’s why early detection is crucial.  

By learning about the symptoms of glaucoma, you can take action quickly, reducing the odds of permanent vision loss. Here’s a look at common signs of glaucoma, as well as when to see your eye care provider.  

The Signs and Symptoms of Glaucoma  

Like many eye conditions, there are several symptoms that could indicate glaucoma. Here is an overview of the primary symptoms people experience.  

Halos  

Seeing halos around light sources could indicate glaucoma, as well as other eye conditions like cataracts. Additionally, they can be side effects from surgery, injury, or symptoms of several different eye diseases.  

With glaucoma, the halos occur due to fluid buildup in the eye. As the fluid increases, it distorts incoming light, creating the bright circles known as halos.  

Vision Loss  

Vision loss in one eye or the development of a blind spot in your visual field could be a symptom of glaucoma. Even if the vision changes are small, the situation is urgent. Glaucoma’s impact on the optic nerve is gradual. By getting it checked quickly, you reduce the odds of permanent or increasingly severe vision loss.  

Cloudiness  

A cloudy-looking eye is another symptom of glaucoma. Glaucoma is a condition characterized by fluid buildup in the eye. When fluid increases, the pressure in the eye rises. Once the pressure reaches a certain point, fluid can get pushed into the cornea, giving it a noticeably cloudy appearance.  

Light Sensitivity  

Since glaucoma can increase pressure in the eye, it can cause light sensitivity. As a result, sensitivity to light can be an early sign of glaucoma, potentially occurring before other vision changes or outward symptoms, like cloudiness.  

Eye Pain  

Sudden and severe eye pain is always worrisome. Not only can it be a symptom of acute glaucoma, but it may also be a sign of other eye conditions, many of which are serious.  

When You Should See Your Eye Care Provider  

Ideally, you should see your eye care provider annually as part of your standard healthcare routine. Often, your eye doctor can detect glaucoma during an exam far before outward symptoms develop, allowing them to intervene quickly and save your vision.  

However, if you experience any of the symptoms above or other kinds of vision changes or eye-related concerns, schedule an appointment with your eye care provider immediately. Vision changes, unexplained pain, and other symptoms can be indicative of numerous conditions, some of which are serious and require immediate care. By acting fast and scheduling an appointment, you’re doing your part to care for your eye health.

What Are the Types of Glaucoma?

January is Glaucoma Awareness month, a time of year where we take a close look at the condition and focus on sharing information to help patients maintain their eye health. While we covered the basics in a recent article – Understanding Glaucoma – we wanted to seize this opportunity to take a deeper dive into the topic.  

Glaucoma is often thought of as a single eye condition. However, there is more than one type of glaucoma, each with its own unique characteristics.  

If you are diagnosed with glaucoma, it’s wise to explore more about your specific variant. That way, you won’t just know more about how the condition is impacting your eye health, but also how the treatment options and outcomes can differ.  

Here’s a look at each of the types of glaucoma, including their characteristics, treatment options, and more.  

Open-Angle Glaucoma  

Open-angle glaucoma is the most common form of the condition. With open-angle glaucoma, the angle between the cornea and the iris is wide and open, essentially the way it is meant to be. Issues arise when the drainage canals become blocked, preventing proper fluid flow and leading to fluid accumulation.  

As the fluid builds up, the pressure increases. That pressure ultimately causes damage to the optic nerve, disrupting vision signals between the eye and the brain.  

Many people with open-angle glaucoma are initially unaware they have the condition. The fluid buildup usually happens slowly over time and doesn’t typically result in physical discomfort. Typically, people with open-angle glaucoma only become aware once they begin experiencing vision loss unless it is caught earlier during a standard eye exam.  

Open-angle glaucoma can lead to significant vision loss, up to blindness. With proper treatment, damage can be mitigated or slowed, potentially preserving your vision. However, there is no cure for any form of glaucoma, including open-angle.  

Acute Angle-Closure Glaucoma  

Angle-closure glaucoma is also the result of fluid buildup. However, fluid flow is disrupted due to the narrowing of the entrance points of the drainage canals. At times, those openings are simply too small to allow for proper fluid flow. However, they can also be shut entirely, either by design or due to clogging.  

With angle-closure glaucoma, symptoms typically appear quickly. Along with vision loss, eye pain, headaches, and nausea commonly occur. There may also be eye redness as well as a halo effect around lights.   

Angle-closure glaucoma causes vision loss and may lead to blindness. It is also considered a medical emergency. As with open-angle glaucoma, there isn’t a cure. Though, with quick treatment, it’s possible to reduce the harmful effects of the condition.  

Normal-Tension Glaucoma  

With normal-tension glaucoma, pressure isn’t the issue, though optic nerve damage still occurs, resulting in vision changes or loss. In some cases, trauma may be to blame. In others, it could be heightened optic nerve sensitivity, blood flow issues, or circulation impairments.  

Normal-tension glaucoma, like the other versions, also can’t be cured. However, it can be managed, especially if caught early.
