๐ What is Glaucoma Suspect?
A glaucoma suspect is not yet diagnosed with glaucoma,
but shows risk factors or suspicious findings.
๐ Diagnostic Features
FindingDefinition
| Ocular Hypertension | IOP ≥ 21 mmHg |
| Optic Disc Suspicion | VCDR ≥ 0.6, rim thinning/notching |
| RNFL Changes | Retinal nerve fiber layer defects |
| Visual Field Changes | Possible glaucomatous field loss |
โ True glaucoma = Requires both structure & function abnormalities
โ What is Ocular Hypertension?
- A subtype of glaucoma suspect
- Elevated IOP with no optic nerve or visual field damage
๐ Risk of Progression & Need for Treatment
GroupGlaucoma Conversion Rate (per year)
| High risk | 4% |
| Low risk | 2% |
| Treated preventively | 1% |
๐งช Management by Risk Group
Risk LevelExamplesAction
| High | IOP ≥ 30 mmHg, VCDR ≥ 0.7, thin CCT, age ↑, VF abnormality | Start treatment |
| Moderate | Borderline IOP (20–30), partial risk factors | Close follow-up ± meds |
| Low | IOP ~21–23 mmHg, no other findings | Monitor q6–12 months |
โ Summary
- Glaucoma suspect ≠ Glaucoma, but requires risk stratification
- Ocular hypertension is the most common form
- Only high-risk patients need treatment
- Low-risk patients can be monitored regularly
