Glaucoma Screening in Korea: When and Why You Need It
Glaucoma Screening in Korea: When and Why You Need It
Introduction
Glaucoma is a serious eye condition that can gradually damage the optic nerve and lead to permanent vision loss if it is not detected and managed early. One of the biggest challenges with glaucoma is that many patients do not experience noticeable symptoms during the early stages.
Regular glaucoma screening is important because early detection allows ophthalmologists to monitor changes and recommend appropriate treatment before significant vision damage occurs.
In South Korea, advanced ophthalmology clinics and eye hospitals provide comprehensive glaucoma evaluations using modern diagnostic technology, including eye pressure measurements, optic nerve examinations, visual field testing, and retinal imaging. These services are available for local residents, expats, and international patients seeking preventive eye care.
For people at higher risk of glaucoma, routine screening can be an important part of long-term eye health management. Understanding when to get screened, what tests are involved, and why early detection matters can help patients make informed decisions.
This guide explains glaucoma screening in Korea, including risk factors, diagnostic tests, screening schedules, treatment options, costs, and what international patients should know.
What Is Glaucoma?
Understanding glaucoma
Glaucoma is a group of eye diseases that damage the optic nerve, which sends visual information from the eye to the brain.
The most common form is associated with increased pressure inside the eye, although glaucoma can also occur with normal eye pressure.
Over time, optic nerve damage may lead to:
- Loss of peripheral vision
- Difficulty seeing in low light
- Reduced visual field
- Permanent vision impairment
Why glaucoma is called a silent eye disease
Many glaucoma patients do not notice symptoms until the disease has progressed.
Early stages may occur without:
- Eye pain
- Blurry vision
- Noticeable vision loss
This is why regular screening is essential, especially for people with risk factors.
Why Glaucoma Screening Is Important
Detecting glaucoma early
Early glaucoma detection allows doctors to:
- Monitor optic nerve changes
- Track disease progression
- Start treatment when appropriate
Because optic nerve damage cannot usually be reversed, prevention and early management are key goals.
Protecting long-term vision
Regular screening helps preserve vision by identifying changes before severe damage occurs.
Ophthalmologists can create personalized monitoring plans based on:
- Age
- Eye pressure
- Family history
- Eye structure
- Previous test results
Identifying hidden risk factors
A glaucoma screening can reveal risk factors even before noticeable symptoms develop.
This is especially important for people who may not realize they have increased risk.
Who Needs Glaucoma Screening in Korea?
Adults over 40
The risk of glaucoma generally increases with age.
People over 40 may benefit from regular eye examinations, especially if they have additional risk factors.
People with a family history of glaucoma
Having a close family member with glaucoma may increase the likelihood of developing the condition.
Regular monitoring can help detect early changes.
People with high myopia
High levels of nearsightedness are associated with increased glaucoma risk.
Patients with high myopia may require more detailed evaluations.
Patients with diabetes or other health conditions
Certain medical conditions may increase the risk of eye problems.
Regular eye examinations can help monitor overall eye health.
People using steroid medications
Long-term use of steroid medications may increase eye pressure in some individuals.
Patients using steroids should discuss glaucoma screening with an eye specialist.
Patients considering vision correction surgery
People planning procedures such as:
- LASIK
- SMILE Pro
- LASEK
- ICL
may require glaucoma evaluation as part of their preoperative eye assessment.
Glaucoma Screening Tests in Korea
Eye pressure measurement
Intraocular pressure testing measures the pressure inside the eye.
Although high pressure is a major glaucoma risk factor, normal eye pressure does not completely rule out glaucoma.
Optic nerve examination
Doctors examine the optic nerve to identify possible signs of damage.
This evaluation helps assess:
- Nerve appearance
- Structural changes
- Glaucoma-related concerns
Optical Coherence Tomography (OCT)
OCT is an advanced imaging test that creates detailed images of the retina and optic nerve.
It helps doctors evaluate:
- Nerve fiber thickness
- Structural changes
- Disease progression
Visual field test
A visual field test measures how well a person can see objects in different areas of vision.
It helps detect:
- Peripheral vision loss
- Functional changes caused by glaucoma
Gonioscopy
This test examines the drainage angle of the eye.
It helps doctors identify the type of glaucoma and determine appropriate management.
When Should You Get Glaucoma Screening?
Routine screening for adults
The recommended screening schedule depends on:
- Age
- Family history
- Eye condition
- Medical risk factors
People with higher risk may need more frequent monitoring.
Before vision correction procedures
Patients considering laser eye surgery or implantable lenses should undergo detailed eye assessments.
Doctors evaluate:
- Eye pressure
- Optic nerve health
- Overall eye condition
When experiencing possible warning signs
Although early glaucoma may not cause symptoms, patients should seek evaluation if they notice:
- Gradual vision changes
- Difficulty adjusting to darkness
- Loss of peripheral vision
- Unexplained visual problems
Glaucoma Treatment Options in Korea
Eye drops
Prescription eye drops are commonly used to help control eye pressure.
They may work by:
- Reducing fluid production
- Improving fluid drainage
Treatment depends on the type and severity of glaucoma.
Laser treatment
Some patients may benefit from laser procedures designed to improve fluid drainage or reduce eye pressure.
Surgery
For advanced cases or when other treatments are insufficient, surgical options may be considered.
An ophthalmologist will recommend treatment based on individual circumstances.
