Senior’s Eyes and Glaucoma: What Seniors and Caregivers Should Know

Victoria Senior Health  |  December 13, 2023

What Every Senior in Victoria, BC Needs to Know About Glaucoma and Senior Eye Health

Glaucoma is a collection of conditions that can harm the optic nerve and lead to loss of vision and is the second most common cause of blindness. Typically, it develops as a gradual increase in intraocular pressure and can cause up to 40% of vision loss without presenting noticeable symptoms. Yet, with prompt intervention, serious vision impairment can be prevented.

Why Do Some Seniors Develop Glaucoma?

Located at the front of the eye is the anterior chamber, where a clear fluid continuously circulates to nourish nearby tissues. This fluid exits through the open angle, formed by the cornea and iris, and flows through a spongy meshwork acting as a drain before leaving the eye.

However, there are cases where the fluid does not drain quickly enough through this meshwork. As a result, pressure builds up inside the eye, potentially causing damage to the optic nerve and leading to vision loss. As such, regulating intraocular pressure is crucial in maintaining eye health.

Above all, glaucoma is not a guaranteed outcome for individuals with elevated eye pressure. A percentage of adults can effectively manage higher levels of eye pressure. A professional, thorough, and dilated eye exam will determine the patient’s baseline for healthy eye pressure.

Most Common Types of Glaucoma in Seniors

#1. Open-angle Glaucoma:

The most prevalent form of glaucoma is open-angle glaucoma, which impacts approximately 3 million individuals in the United States. It causes a gradual reduction of peripheral vision without causing any pain. This occurs when the drainage canals in the eye become obstructed over an extended period.

The resulting vision resembles that of looking through a paper towel roll. Typically, there are no signs or symptoms in the early stages, and individuals may not experience any vision loss for several years. However, if detected early and treated promptly, this type of glaucoma can often be managed successfully with medication.

#2. Low-Tension or Normal-Tension Glaucoma:

Normal-Tension Glaucoma, also known as Low-Tension Glaucoma, can cause optic nerve damage and narrowing of peripheral vision. This form of glaucoma is typically associated with normal eye pressure levels. With medication, some may experience a 30% decrease in eye pressure with improved symptoms.

However, in other cases, the disease may still progress despite lower pressures. It is crucial to consider a comprehensive medical background when determining potential risk factors for this condition, including low blood pressure. If no risk factors are present, the treatment options for Normal-Tension Glaucoma are the same as those for open-angle glaucoma.

#3. Angle-Closure Glaucoma:

Angle-Closure Glaucoma is a condition where the fluid at the front of the eye is obstructed by part of the iris. This obstruction leads to a rapid rise in eye pressure. Indications include intense pain and nausea, along with redness and blurred vision. Urgent medical attention is required if you or anyone is your care experiences these symptoms.

On the other hand, left untreated, this type of glaucoma can cause permanent blindness in one to two days. However, timely intervention through laser surgery and medication can remove the blockage and preserve vision.

#4. Rare Types of Glaucoma:

There are also rare types of glaucoma that can affect seniors. In addition to common forms, there are also uncommon variations of glaucoma that may impact older individuals. One such type is known as pigmentary glaucoma, in which the iris sheds pigment and obstructs the meshwork, impeding fluid drainage and posing a significant threat to lifelong vision. Another type, known as trauma-related glaucoma, can result from a severe eye injury or exposure to chemicals or objects that penetrate the eye.

What Seniors Can Do About Glaucoma?

Currently, no remedy exists for glaucoma. Yet, medication or surgery can aid in decreasing or avoiding additional deterioration of vision. The suitable course of action varies based on the specific type of glaucoma a person is experiencing.

As time passes, certain medications may lose their effectiveness or may not react well with other prescribed medications. It is essential for a physician to carefully oversee both glaucoma and its associated medications. If you are undergoing treatment for this condition, it is crucial to consistently take your glaucoma medicine daily.

According to research, the most effective method for managing the disease is to catch it early and seek treatment before significant vision loss occurs. It is important to schedule regular eye exams with a professional who can examine your eyes with dilated pupils. Starting at age 40, it is recommended to have an exam every two to four years, increasing to yearly exams after reaching 55. For individuals over 50 with a family history of glaucoma, it is advised to have yearly exams.
