Glaucoma is a common eye condition that affects millions of people worldwide. It is one of the leading causes of irreversible blindness, making it a significant public health concern. Understanding what age does glaucoma start is essential for early detection and prevention of vision loss.
This blog post will explore the age at which glaucoma typically begins, factors that influence its onset, and steps to manage the condition.
What Age Does Glaucoma Start?
Glaucoma is a group of eye diseases that cause damage to the optic nerve, often due to increased pressure inside the eye. The optic nerve is crucial for transmitting visual information from the eye to the brain. When this nerve becomes damaged, vision is compromised, and if left untreated, it can lead to blindness.
The two main types of glaucoma are open-angle glaucoma and angle-closure glaucoma. Open-angle glaucoma is the most common form and progresses slowly, while angle-closure glaucoma can develop suddenly and requires immediate attention.
Both types can affect people of all ages, but understanding what age does glaucoma start helps in identifying who is most at risk and when to begin monitoring.
Glaucoma in Infants and Children
While glaucoma is most often associated with older adults, it can occur in infants and children. This form is known as congenital or pediatric glaucoma. Congenital glaucoma is rare and is usually diagnosed within the first year of life. It occurs due to abnormal development of the eye’s drainage system, leading to increased intraocular pressure (IOP).
Children with congenital glaucoma may show symptoms such as excessive tearing, light sensitivity, and unusually large eyes. Parents and pediatricians play a critical role in early detection and treatment. Surgery is often required to correct the condition, as untreated congenital glaucoma can lead to severe vision loss or blindness.
Glaucoma in Young Adults
Juvenile glaucoma occurs in individuals between the ages of 10 and 40. This type of glaucoma is also rare but should not be overlooked. Juvenile glaucoma is often hereditary, meaning that individuals with a family history of glaucoma are at higher risk.
Young adults with juvenile glaucoma may not exhibit noticeable symptoms until the disease progresses significantly. Regular eye exams are crucial for early diagnosis, especially for those with a family history of the condition. Eye care professionals can measure intraocular pressure and examine the optic nerve to identify signs of damage.
Primary Open-Angle Glaucoma and Middle Age
Primary open-angle glaucoma (POAG) is the most common type of glaucoma and typically starts in middle age, often between 40 and 60 years old. POAG progresses slowly and is often referred to as the “silent thief of sight” because it can go unnoticed until significant vision loss occurs.
Risk factors for POAG include age, family history, ethnicity, and certain medical conditions such as diabetes and hypertension. African Americans and Hispanics are at higher risk of developing POAG at an earlier age compared to other populations. Understanding what age does glaucoma start in specific demographic groups is vital for targeted screening and prevention strategies.
Angle-Closure Glaucoma and Older Adults
Angle-closure glaucoma is less common than POAG but is more likely to cause sudden and severe symptoms. This type of glaucoma typically affects older adults, particularly those over the age of 60. Women and individuals with smaller eyes are at higher risk due to the anatomy of their eye structures.
Symptoms of angle-closure glaucoma include severe eye pain, blurred vision, nausea, and vomiting. Because it can develop rapidly, this form of glaucoma is considered a medical emergency. Prompt treatment, often involving medication or surgery, is necessary to prevent permanent vision loss.
Risk Factors Influencing the Onset of Glaucoma
Several factors can influence the age at which glaucoma starts. These include:
- Family History: Individuals with a parent or sibling with glaucoma are more likely to develop the condition earlier in life.
- Ethnicity: Certain ethnic groups, such as African Americans, Asians, and Hispanics, are at higher risk of developing glaucoma at a younger age.
- Medical Conditions: Diabetes, high blood pressure, and other systemic diseases can increase the risk of glaucoma.
- Eye Injuries: Trauma to the eye can lead to secondary glaucoma, which may develop years after the injury.
- Medications: Long-term use of corticosteroids can increase intraocular pressure and the risk of glaucoma.
By recognizing these risk factors, individuals can take proactive steps to reduce their risk and monitor their eye health more closely.
The Importance of Regular Eye Exams
Regular eye exams are the most effective way to detect glaucoma early. The American Academy of Ophthalmology recommends a comprehensive eye exam every two to four years for individuals under 40, every one to three years for those aged 40 to 54, and every one to two years for individuals aged 55 and older. High-risk individuals may need more frequent screenings.
During an eye exam, an ophthalmologist or optometrist will perform tests to measure intraocular pressure, examine the optic nerve, and assess peripheral vision. These tests are non-invasive and can provide valuable information about the health of your eyes.
Managing and Treating Glaucoma
Once glaucoma is diagnosed, the goal of treatment is to lower intraocular pressure and prevent further optic nerve damage. Treatment options include:
- Medications: Eye drops are often the first line of treatment. They help reduce intraocular pressure by decreasing fluid production or improving fluid drainage.
- Laser Therapy: Procedures such as laser trabeculoplasty can improve fluid drainage in the eye.
- Surgery: In cases where medications and laser therapy are not effective, surgical options such as trabeculectomy or the insertion of drainage implants may be considered.
- Lifestyle Adjustments: Maintaining a healthy lifestyle, including regular exercise and a balanced diet, can help manage glaucoma risk factors.
By following a personalized treatment plan, individuals with glaucoma can protect their vision and maintain their quality of life.
Frequently Asked Questions

What is the earliest age glaucoma can start?
Glaucoma can start at any age, including infancy, in the form of congenital glaucoma. This type is rare and often diagnosed within the first year of life.
Can young adults develop glaucoma?
Yes, young adults can develop juvenile glaucoma, which typically occurs between the ages of 10 and 40. It is often hereditary and may not show symptoms until later stages.
What age is most common for primary open-angle glaucoma?
Primary open-angle glaucoma most commonly starts between the ages of 40 and 60, progressing gradually over time.
Is glaucoma more common in older adults?
Yes, glaucoma is more common in older adults, particularly those over the age of 60. Age is a significant risk factor for developing the condition.
What are the symptoms of congenital glaucoma?
Symptoms of congenital glaucoma include excessive tearing, light sensitivity, and enlarged eyes. These symptoms typically appear in infants and young children.
Who is most at risk of developing glaucoma?
People with a family history of glaucoma, African Americans, Hispanics, individuals over 60, and those with conditions like diabetes are at higher risk.
How often should I have an eye exam to check for glaucoma?
Eye exams are recommended every 2–4 years for individuals under 40, every 1–3 years for those 40–54, and every 1–2 years for those 55 and older. High-risk individuals may need more frequent screenings.
What is the difference between open-angle and angle-closure glaucoma?
Open-angle glaucoma progresses slowly and is often asymptomatic, while angle-closure glaucoma develops suddenly with symptoms like severe eye pain and blurred vision.
Can glaucoma be treated or cured?
Glaucoma cannot be cured, but it can be managed through medications, laser therapy, surgery, and lifestyle adjustments to prevent further vision loss.
The Bottom Line: What Age Does Glaucoma Start?
Glaucoma can start at any age, from infancy to older adulthood, depending on the type and risk factors involved. Congenital glaucoma affects infants, juvenile glaucoma impacts young adults, and primary open-angle glaucoma typically begins in middle age. Older adults are more likely to experience angle-closure glaucoma, which requires immediate attention.
