How to Follow Up If There Is a Family History of Glaucoma? Dr. Anuradha Chandra

Introduction

Glaucoma is often known as a “silent” eye disease because it can damage the optic nerve without causing noticeable symptoms in its early stages. If glaucoma runs in your family, especially in a parent or sibling, you may have a higher risk of developing the condition.

However, having a family history of glaucoma does not mean that you will definitely develop it. Regular eye examinations can help detect early changes and protect your vision.

When Should You Start Screening?

There is no single screening schedule for everyone. Your age, family history and other risk factors determine when you should begin and how frequently you should have your eyes checked.

If a close family member has glaucoma—particularly if they were diagnosed at a young age—inform your ophthalmologist.

Do not wait for symptoms before getting tested.

What Tests Are Needed If Glaucoma Runs in Your Family?

A simple eye-pressure check is not enough to rule out glaucoma. A comprehensive glaucoma evaluation by your Doctor may include several examinations depending on your age, symptoms and individual risk profile.

1. Eye Pressure Measurement

Intraocular pressure (IOP) is measured during an eye examination. Raised eye pressure is an important risk factor, but glaucoma can sometimes occur even when eye pressure is within the statistically normal range.

2. Optic Nerve Examination

The optic nerve is carefully examined for signs of damage or changes that may be associated with glaucoma.

3. Visual Field Test

A visual field examination assesses peripheral vision and can identify functional changes that may not be noticeable in everyday life.

4. OCT Scan

Optical Coherence Tomography (OCT) can provide detailed images of structures such as the retinal nerve fibre layer and help the ophthalmologist monitor subtle structural changes over time.

5. Gonioscopy

In appropriate patients, gonioscopy allows the doctor to examine the drainage angle of the eye and helps determine the type and risk profile of glaucoma.

6. Corneal Thickness Measurement

Corneal thickness can influence how eye-pressure measurements are interpreted and may form part of a comprehensive glaucoma risk assessment.

Your ophthalmologist will decide which investigations are appropriate based on your individual risk factors.

How Often Should You Follow Up?

The frequency of follow-up depends on your individual risk. Your ophthalmologist may recommend examinations for every year or more frequently if you have additional risk factors or suspicious findings.

Regular follow-up also allows your doctor to compare current test results with previous examinations and identify subtle changes over time.

Should Children Be Tested If a Parent Has Glaucoma?

This depends on the type of glaucoma and the family history.

A child whose parent has adult-onset glaucoma does not automatically have glaucoma. However, if there is a history of childhood, congenital or juvenile glaucoma, the family history should be discussed with a pediatric ophthalmologist.

Dr. Anuradha Chandra has specialized expertise in pediatric ophthalmology as well as pediatric glaucoma surgery, making a specialist assessment particularly important when glaucoma occurs at a young age in a family.

Why Regular Screening Matters

Early glaucoma may have no obvious symptoms, while vision lost due to glaucoma generally cannot be restored. Detecting the disease early and monitoring it regularly can help protect the remaining vision.

If glaucoma runs in your family, make sure your eye doctor knows about it and follow the screening schedule recommended for you.

What Information Should You Tell Your Eye Doctor?

Before your appointment with Dr. Anuradha Chandra | Glaucoma, try to find out:

• Which family member has glaucoma?

• Is it your parent, sibling, child or another relative?

• What type of glaucoma were they diagnosed with?

• At what age were they diagnosed?

• Did they require eye drops, laser treatment or surgery?

• Did they experience significant vision loss?

• Does more than one family member have glaucoma?

This information can help your ophthalmologist understand your family history and determine an appropriate monitoring strategy.

Don't Wait for Symptoms

One of the biggest misconceptions about glaucoma is that you will know when something is wrong with your eyes.

Unfortunately, early glaucoma may have no obvious symptoms. By the time peripheral vision loss becomes noticeable, damage to the optic nerve may already have occurred. Vision already lost from glaucoma cannot generally be restored, which is why early detection and continued monitoring are so important.

If glaucoma runs in your family, don't wait for blurred vision or other symptoms before getting your eyes examined.
