Treatment Overview
The Early Glaucoma Detection Screening Program in Korea is a specialized diagnostic system designed to identify glaucoma at its earliest and most treatable stages—even before symptoms or visual field defects appear. Since glaucoma often progresses silently, early detection is essential for preventing irreversible optic nerve damage and long-term vision loss.
Korean ophthalmology centers lead globally in early glaucoma screening through the integration of:
- High-resolution OCT and RNFL thickness mapping
- OCT Angiography (OCTA) for microcirculation analysis
- AI-powered optic nerve damage prediction models
- Digital visual field pre-perimetry tests
- Corneal thickness and biomechanics assessment
- Risk scoring based on genetics, anatomy, and systemic factors
This program provides early identification of glaucoma susceptibility and pre-disease markers, enabling immediate preventive strategies.
Purpose & Benefits
Purpose
- Detect glaucoma before symptoms develop
- Identify structural optic nerve damage earlier than visual field loss
- Evaluate risk factors such as thin cornea or optic nerve vulnerability
- Establish baseline measurements for lifelong monitoring
- Determine the need for preventive therapies or closer follow-up
- Prevent long-term vision impairment through early intervention
Benefits
- Ultra-early detection of glaucoma structural changes
- AI-enhanced analysis for high-risk patients
- Greater accuracy than standard vision tests
- Personalized risk assessment and follow-up intervals
- More effective long-term disease management
- Prevention-focused care minimizing the chance of late diagnosis
- Particularly beneficial for NTG-prone populations, common in Korea
Ideal Candidates
The Early Glaucoma Detection Screening Program in Korea is ideal for:
- Individuals over age 40
- Patients with a family history of glaucoma
- People with high myopia or hyperopia
- Individuals with thin corneas or large optic nerve cups
- Patients with migraines, sleep apnea, or systemic vascular issues
- Those who have fluctuating or borderline IOP
- Patients of Asian descent, who have higher NTG prevalence
- Anyone seeking a comprehensive preventive eye health evaluation
Possible Risks & Complications
The program is non-invasive and extremely safe. The underlying glaucoma risks that may be identified include:
- Early optic nerve fiber loss
- Reduced optic nerve perfusion
- High-risk anatomical angles
- Genetic susceptibility to glaucoma
- Hidden IOP fluctuations
- NTG-type damage despite normal IOP readings
Korean specialists reduce risks using:
- AI-based damage prediction tools
- Regular OCT and visual field trend mapping
- Preventive medication for high-risk patients
- Early scheduling of laser or MIGS when needed
Surgical Techniques
(These procedures may be recommended if screening detects early signs of glaucoma or high-risk conditions.)
1. Selective Laser Trabeculoplasty (SLT)
Used as an early intervention for high-risk or borderline glaucoma patients.
2. Laser Peripheral Iridotomy (LPI)
Performed for patients with narrow angles or risk of angle closure.
3. MicroPulse Laser Therapy
Ideal for patients with early NTG showing vascular-related optic nerve stress.
4. MIGS (Minimally Invasive Glaucoma Surgery)
Considered in early cases with progression risk:
- iStent Inject
- Hydrus Microstent
- KDB Goniotomy
- Canaloplasty
- GATT
5. Medication Prevention Protocols
Low-dose or selective therapy may be started to prevent optic nerve damage in high-risk eyes.
Treatment Process in Korea
Step 1 – Comprehensive Baseline Diagnostic Evaluation
Includes OCT, OCTA, corneal thickness tests, IOP measurement, and optic nerve imaging.
Step 2 – AI-Based Glaucoma Risk Scoring
Evaluates genetics, anatomy, age, corneal biomechanics, and optic nerve microstructure.
Step 3 – Early Damage Detection
Identifies RNFL thinning, microcirculation deficits, or subtle optic nerve changes.
Step 4 – Personalized Prevention Strategy
May include medication, lifestyle guidance, or scheduling preventive laser procedures.
Step 5 – Follow-Up Monitoring
Routine evaluations scheduled based on risk level (every 3–12 months).
Evaluation Duration: 20–40 minutes
Setting: Outpatient glaucoma diagnostic center
Recovery & After-Care
After-Care Guidelines
- Maintain scheduled follow-ups for early detection
- Inform the clinic of visual symptoms such as halos or dimming
- Follow preventive treatment plans if initiated
- Protect eye health with UV protection and proper eye care habits
- Maintain systemic health (blood pressure, sleep quality) to reduce glaucoma risk
Recovery Timeline
Immediately: All diagnostic tests completed without downtime
Days 1–7: Results analyzed and prevention plan finalized
Weeks 2–4: Early changes monitored if needed
1–12 Months: Ongoing follow-up and early intervention managed
