Glaucoma is a group of eye diseases that can lead to irreversible vision loss by damaging the optic nerve, which transmits visual information from the eye to the brain. Often termed the “silent thief of sight,” glaucoma typically progresses without noticeable symptoms until significant vision loss has occurred. In Australia, it’s estimated that over 300,000 people are affected by glaucoma, with more than 50% remaining undiagnosed.
The exact cause of glaucoma isn’t fully understood, but several risk factors contribute to its development:
Increased Intraocular Pressure (IOP): Elevated pressure within the eye is a major risk factor for optic nerve damage.
Family history: A family history of glaucoma increases the likelihood of developing the condition.
Age: Individuals over 40 are at higher risk.
Medical conditions: Conditions like diabetes and high blood pressure can elevate risk.
While glaucoma itself may not be entirely preventable, early detection and management are crucial in preventing vision loss. Regular comprehensive eye examinations, especially for those over 40 or with a family history of glaucoma, are essential. Maintaining a healthy lifestyle, managing underlying health conditions, and protecting your eyes from injury can also help reduce risk.
Glaucoma often develops without noticeable symptoms in its early stages. As the disease progresses, individuals may experience:
Peripheral vision loss: Gradual loss of side vision, often unnoticed until significant damage has occurred.
Acute angle-closure glaucoma: This less common form can present suddenly with severe eye pain, blurred vision, headache, nausea, and redness of the eye. This is a medical emergency requiring immediate attention.
While there’s no cure for glaucoma, various treatments can effectively manage the condition and prevent further vision loss:
Eye drops: The most common treatment, eye drops help reduce intraocular pressure by decreasing fluid production or increasing fluid outflow in the eye.
Laser treatment: Procedures like laser trabeculoplasty improve drainage within the eye, helping to lower pressure.
Surgery: In cases where medications and laser treatments are insufficient, surgical options can create new drainage pathways.
Adherence to prescribed treatments and regular follow-up appointments with eye care professionals are vital to effectively manage glaucoma.
When should I see an optical professional?
It’s recommended to have regular eye examinations every two years, especially if you’re over 40 or have risk factors for glaucoma. If you experience symptoms like sudden eye pain, blurred vision, or halos around lights, seek immediate medical attention, as these could indicate acute angle-closure glaucoma. Early detection through routine check-ups is key to preserving vision.
