What Are the Early Signs of Glaucoma?
Glaucoma is a group of eye conditions that can damage the optic nerve, often due to increased intraocular pressure. In its early stages, glaucoma may not cause noticeable symptoms.
Because early glaucoma is frequently symptom-free, regular eye examinations are critical for early detection.
A structured Comprehensive Eye Test includes assessment of eye pressure and optic nerve health.
Does Glaucoma Cause Symptoms Early On?
In many cases, early glaucoma does not cause pain or obvious visual changes.
Gradual peripheral (side) vision loss may occur slowly and often goes unnoticed. Central vision is typically preserved until later stages.
This is why glaucoma is sometimes referred to as a “silent” condition.
Possible Early Warning Signs
Although many patients experience no symptoms, some may notice:
- Subtle peripheral vision changes
- Difficulty seeing in low light
- Mild headaches (more common in angle-closure glaucoma)
- Halos around lights (more common in angle-closure glaucoma)
These symptoms can also have other causes, so it’s important to have them checked by your optometrist.
Acute angle-closure glaucoma is rare but may cause sudden severe pain, nausea and blurred vision. This requires urgent medical attention. If you have sudden severe eye pain, redness, nausea or blurred vision, go to your nearest emergency department or call 000.
Who Is at Higher Risk?
Risk factors may include:
- Age over 40
- Family history of glaucoma
- Higher eye pressure
- Diabetes or blood pressure problems (high or low)
- High short-sightedness (myopia)
- Long-term steroid use
- African or Asian ancestry
Risk assessment and monitoring are part of Glaucoma Screening and Monitoring.
How Is Glaucoma Detected?
Glaucoma cannot be diagnosed based on symptoms alone. Detection requires clinical testing, which may include:
- Intraocular pressure measurement
- Optic nerve evaluation
- Visual field assessment
- Retinal imaging
These assessments are incorporated into structured examination when indicated.
Why Early Detection Matters
Optic nerve damage from glaucoma is irreversible. However, early detection and management can significantly slow progression.
Regular monitoring helps preserve long-term visual function.
