Eye Conditions & Treatments
Macular Degeneration
Age-related macular degeneration (AMD) is one of the leading causes of vision loss, affecting the central part of vision needed for reading, driving, and recognizing faces. It comes in two forms: dry AMD, which progresses gradually, and wet AMD, which can cause sudden vision loss due to abnormal blood vessel growth.
The good news? Early detection and treatment can help slow or even improve vision! Anti-VEGF injections are highly effective in controlling wet AMD, while lifestyle changes and recommended eye supplements can help with dry AMD.
Anti-VEGF Treatment
Understanding the Role of VEGF in Retinal Disease
Vascular Endothelial Growth Factor (VEGF) is a naturally occurring protein in the body that promotes the growth of new blood vessels. While this is important for healing and development, excessive VEGF in the eye can cause serious problems. In retinal diseases such as wet age-related macular degeneration (AMD), diabetic retinopathy, and retinal vein occlusions, VEGF becomes overactive, leading to the growth of abnormal, leaky blood vessels in the retina. These vessels can bleed or leak fluid into the macula—the part of the retina responsible for sharp, central vision—causing distortion, swelling, and vision loss.
This is where Anti-VEGF injections come in. These medications work by blocking VEGF, stopping the growth of harmful blood vessels and reducing fluid leakage.
The treatment is delivered through a small injection into the eye, performed under local anaesthetic in a sterile clinical setting. It is a quick, well-tolerated procedure with minimal discomfort and no need for hospital admission.
In New Zealand, commonly used Anti-VEGF medications include:
- Avastin (Bevacizumab) – An effective, widely used, and cost-efficient option.
- Zaltrap (Aflibercept 25mg/ml) – Occasionally used off-label for retinal conditions.
- Eylea (Aflibercept 40mg/ml) – Specifically designed for retinal diseases, often with longer-lasting effects.
- Vabysmo (Faricimab) – A next-generation injection that blocks both VEGF and Ang-2, potentially reducing treatment frequency.
Anti-VEGF therapy has transformed the treatment landscape for retinal disease. Many patients experience significant improvement or stabilisation of vision, often avoiding the severe vision loss that was once considered inevitable. With regular monitoring and ongoing care, these injections offer a powerful and proven way to protect and restore sight.
If you’ve been diagnosed with a retinal condition, early treatment is key. Speak with your eye specialist to explore the most suitable Anti-VEGF option for your needs and safeguard your vision for the future.
Frequently Asked Questions
At our clinic, we are committed to providing exceptional care and personalised service. Below are answers to some of the most common questions we receive. If you have further enquiries, we warmly invite you to get in touch.
General Eye Health
How often should I have my eyes checked?
We recommend a comprehensive eye examination every one to two years, even if you are not experiencing any vision problems. Patients with diabetes, those over 60, or those with known eye conditions may require more frequent monitoring to maintain optimal eye health.
What are common signs I should see an eye specialist?
Symptoms such as blurred vision, flashes of light, new floaters, eye pain, sudden loss of vision, or difficulty seeing at night may indicate a serious condition. Early assessment by an ophthalmologist can make a significant difference in treatment outcomes.
Can eye diseases be prevented?
While not all eye diseases are preventable, many risks can be reduced with regular check-ups, management of systemic conditions such as diabetes and hypertension, UV eye protection, and maintaining a healthy lifestyle. Early detection remains key to preserving vision.
What is the difference between an optometrist and an ophthalmologist?
Optometrists are trained to assess vision, prescribe corrective lenses, and manage certain eye conditions. Ophthalmologists are medical doctors with advanced training who diagnose and treat all eye diseases and perform surgical procedures when required.
Do I need a referral to see an ophthalmologist?
While a referral from your optometrist or general practitioner can be helpful, it is not always necessary. You are welcome to contact our clinic directly to arrange an appointment.
Eye Surgery
Is cataract surgery painful?
Cataract surgery is generally painless. It is performed under local anaesthetic, ensuring you are comfortable throughout the procedure. Most patients experience a smooth and rapid recovery, with significant improvements in vision within a few days.
How long does cataract or vitrectomy surgery take?
Cataract surgery typically takes around 20 to 30 minutes. Vitrectomy surgery may take longer, depending on the complexity of the case, usually between 45 minutes and two hours. Both procedures are commonly performed as day surgeries, allowing you to return home the same day.
How long does it take to recover from vitrectomy surgery?
Recovery varies according to the underlying condition and surgical approach. Generally, patients notice gradual vision improvement over several weeks. Our team will provide detailed post-operative instructions to support your healing and optimise your outcome.
Will I need to wear glasses after cataract surgery?
Many patients enjoy significantly improved vision after cataract surgery, although some may still require glasses for activities such as reading. Advanced intraocular lens options are available to further reduce dependence on glasses, and we will tailor recommendations to suit your lifestyle and needs.
