Glaucoma: Family History, Detection, and Treatment
Glaucoma is a group of eye diseases that can damage the optic nerve, which carries visual information from the eye to the brain. It often develops gradually without noticeable symptoms, making regular comprehensive eye examinations important.
Does Glaucoma Run in Families?
Yes. Having a parent, sibling, or child with glaucoma increases your risk. A family history does not mean that you will develop glaucoma, but it makes regular monitoring especially important.
Other risk factors include:
Older age
Increased eye pressure
Previous eye injury
Certain medical conditions
Certain eye conditions
Use of some medications, including corticosteroids
Tell your optometrist if glaucoma runs in your family. This information helps determine your examination and monitoring schedule.
How Does Glaucoma Affect the Eyes?
Glaucoma damages the optic nerve. In many cases, changes begin in the peripheral vision and develop so gradually that they are difficult to notice.
Increased eye pressure is an important risk factor, but glaucoma can also occur when eye pressure is within the usual range. For this reason, measuring eye pressure alone cannot detect or rule out glaucoma.
Once optic nerve tissue is damaged, it cannot generally be restored. Early detection and appropriate treatment help protect the remaining healthy nerve tissue.
How Is Glaucoma Detected?
A glaucoma assessment may include:
Eye Pressure Measurement - This measures the pressure inside the eye. Eye pressure is one part of the assessment, but it must be considered alongside other findings.
Optic Nerve Assessment - The appearance and health of the optic nerve are evaluated for signs of damage or change.
Retinal and OCT Imaging - OCT imaging provides detailed images of the optic nerve and retinal nerve fibre layer. These images help establish a baseline and monitor structural changes over time.
Humphrey Visual Field Testing - A Humphrey Visual Field test evaluates peripheral and central areas of vision. It helps identify functional changes and monitor glaucoma over time.
Your optometrist considers these results together with your age, family history, medical history, eye health, and previous examination findings.
Can Glaucoma Be Treated?
Glaucoma cannot currently be cured, but treatment can slow or prevent further optic nerve damage. Treatment options include:
Prescription eye drops
Laser treatment
Surgery
Your treatment plan depends on the type and severity of glaucoma, your eye pressure, optic nerve health, visual field results, and overall eye health. Regular follow-up appointments are essential for monitoring the condition and adjusting treatment when necessary.
Why Regular Eye Examinations Matter
Glaucoma often develops without pain or noticeable symptoms in its early stages. Clear central vision does not rule it out.
Regular comprehensive eye examinations allow your optometrist to assess glaucoma risk, examine the optic nerve, and monitor for changes over time.
To protect your eye health:
Attend regular eye examinations and recommended follow-up visits.
Tell your optometrist about any family history of glaucoma.
Use prescribed eye drops exactly as directed.
Report medication side effects or changes in vision.
