Early Glaucoma Symptoms and Treatment

Glaucoma is a leading cause of blindness worldwide. Although anyone can get glaucoma, older adults are at a higher risk of developing it.

What is glaucoma?

Glaucoma is a group of diseases that cause increased pressure in the eye, resulting in damage to the optic nerve that can lead to permanent vision loss. There are several different types of glaucoma, and some of them may be caused by other medical conditions, according to the National Eye Institute.

Glaucoma affects about 3 million people in the U.S., but only half of those are aware they have it, according to the Glaucoma Research Foundation. This is because early signs and symptoms of glaucoma often go unnoticed.

Early diagnosis and treatment are important to slow the progression of glaucoma, which can affect one or both eyes. Read on to learn what the first signs of glaucoma are and what steps you can take to prevent irreversible vision loss.

What is the first sign of glaucoma?

There are several different types of glaucoma, but the most common type — open-angle glaucoma — usually doesn’t cause any signs, symptoms, or pain. This is why glaucoma is commonly known as “the sneak thief of sight.”

It’s critical to get regular eye exams by an ophthalmologist, an eye doctor who specializes in treating eye diseases and performing surgeries. This is especially important if you’re in a glaucoma high-risk group.

Signs and symptoms of open-angle glaucoma

In open-angle glaucoma, the eye doesn’t drain fluid properly. Over time, eye pressure increases and damages the optic nerve.

This type of glaucoma happens gradually, which is why it usually doesn’t cause any pain or vision changes at first. Vision loss associated with open-angle glaucoma begins with peripheral (side) vision loss, but those who have it may not notice it until the damage to the optic nerve is significant.

Signs and symptoms of acute angle-closure glaucoma

Acute angle-closure glaucoma, also called closed-angle glaucoma or narrow-angle glaucoma, occurs when the iris blocks the eye’s drainage angle, making the eye pressure rise very quickly. Acute angle-closure glaucoma is especially common in older adults, particularly those who have untreated cataracts.

Some early signs and symptoms of acute angle-closure glaucoma in the elderly include the following:

  • Blurred vision that happens suddenly
  • Severe eye pain, often described as an intense, throbbing pain, along with reddening of the eye
  • Headache around the eyes or the forehead
  • Nausea and vomiting accompanied by severe eye pain
  • Seeing halos around lights, such as rainbow-colored circles, or unusual sensitivity to lights

Acute angle-closure glaucoma is a medical emergency that can damage the optic nerve and cause permanent vision loss if it’s not treated promptly. Go to the emergency room or see an ophthalmologist right away if you or a loved one experience these signs and symptoms.

Angle-closure glaucoma can also progress gradually, in which case it is called chronic rather than acute. This type of glaucoma, called chronic angle-closure glaucoma, usually doesn’t cause symptoms until the damage to the optic nerve is severe or until an acute event occurs.

Are older adults at risk for glaucoma?

Anyone can get glaucoma, but seniors are at a higher risk. Other risk factors for glaucoma include the following:

  • Adults over age 60 are six times more likely to develop glaucoma.
  • Hereditary history of open-angle glaucoma increases its risk.
  • Diabetes doubles the risk of developing glaucoma.
  • High blood pressure generally increases glaucoma risk.
  • High dosages ofsteroid inhalers to control severe asthma can increase risk.
  • Previous eye surgeries or injuries, especially blunt trauma, increases risk.
  • Severe nearsightedness increases risk.

How to prevent glaucoma-related vision loss in seniors

Early detection and ongoing monitoring of eye health can help lower the risk of glaucoma-related vision loss.

Understand the risk factors for glaucoma

It’s important to think about many aspects of life history to fully understand the risk for this condition: Do you have a family history of glaucoma? Is diabetesor high blood pressure an issue? Has there ever been trauma to the eye?

Race can also affect risk: African Americans over age 40 are six to eight times more likely to develop glaucoma, and Hispanics and Asians are at an increased risk of developing open-angle glaucoma. These risks are associated with slight differences in the anatomy of the eye. African Americans and Hispanics, for example, have been found to have thinner corneas, which is known to increase the risk of glaucoma.

Even if you or your loved one are not in a high-risk group, it’s important for everyone to have a comprehensive dilated eye screening by age 40. Early diagnosis and treatment of glaucoma can prevent the progression of the disease and permanent vision loss.

Manage diabetes and blood pressure

Take care to manage diabetes and monitor blood pressure to keep such health conditions under control. Don’t skip doctor’s appointments, and be sure to take medications as prescribed. Eating a healthy diet, staying physically active, and not smoking can also help lower risk.

Manage and treat glaucoma                                                 

After a glaucoma diagnosis, it’s important to slow the progression of the disease by reducing risk factors as much as possible and taking medications as prescribed by the doctor. Set reminders for follow-up appointments and exams to help prevent any additional vision loss.

Glaucoma-related vision loss can affect quality of life and the ability to perform basic activities of daily living, such as walking, reading, or driving. If your aging loved one has glaucoma and suffers from vision loss, consider whether home care or a move to an assisted living community can help them maintain their independence and happiness.
