Glaucoma
Toowoomba-based glaucoma diagnosis and treatment including MIGS
At Toowoomba Ophthalmic Consultants, we use advanced Heidelberg Spectralis OCT technology to detect and manage glaucoma with precision. Dr David Holcombe provides expert care, including minimally invasive glaucoma surgery (MIGS), to help preserve your vision.
What is glaucoma?
Glaucoma refers to a group of eye diseases that damage the optic nerve, the cable that connects your eye to your brain. This damage is often caused by elevated intraocular pressure and, if left untreated, leads to permanent loss of peripheral vision . The condition is particularly dangerous because:
- Peripheral vision loss is not detectable by the patient in early stages
- Vision loss from glaucoma is permanent and irreversible
- You can have glaucoma and be completely unaware you are losing vision
Who is at risk of glaucoma?
Glaucoma can affect anyone, but certain factors increase your risk. The table below outlines who is most at risk.
| Risk Factor | Increased Risk |
|---|---|
| General Australian population (over 40) | 2–3% develop glaucoma |
| First-degree relative with glaucoma | Risk increases to almost 1 in 4 |
| Over 50 years of age | Risk increases with age |
| People of African or Asian descent | More common |
The Heidelberg Spectralis OCT advantage
Our practice was the first in Toowoomba to use the Heidelberg Spectralis OCT for glaucoma assessment. This advanced imaging technology:
- Measures retinal nerve fibre layer thickness with exceptional precision
- Detects glaucomatous changes before they appear on standard visual field tests
- Allows for earlier treatment than would otherwise be possible
- Tracks disease progression over time with high-resolution optic nerve head images
What is the treatment for glaucoma?
While glaucoma cannot be cured, treatment can slow or stop disease progression. Dr Holcombe offers a full range of treatment options, from eye drops to advanced surgical procedures.
1. Eye Drop Medication
Medicated eye drops are the most common first-line treatment and work by either reducing fluid production or increasing fluid drainage from the eye .
2. Selective Laser Trabeculoplasty (SLT)
SLT is a laser procedure that improves fluid drainage from the eye. It can be used as primary treatment or when eye drops are not effective or well-tolerated.
3. Minimally Invasive Glaucoma Surgery (MIGS)
Dr Holcombe performs MIGS procedures: a newer, less invasive surgical option. This involves inserting a microscopic drainage device into the eye's natural drainage pathway during cataract surgery . Benefits include:
- Enhanced fluid drainage from the eye
- Reduced eye pressure
- Many patients can reduce or cease their glaucoma eye drops altogether
4. Traditional Glaucoma Surgery
For more advanced disease, traditional surgery (trabeculectomy or tube shunt implantation) may be recommended.

Frequently Asked Questions
What glaucoma treatment options are available in Toowoomba?
In Toowoomba, glaucoma can be managed with a range of treatments depending on the severity of your condition. Options include medicated eye drops to lower intraocular pressure, selective laser trabeculoplasty (SLT), minimally invasive glaucoma surgery (MIGS), and traditional glaucoma surgery such as trabeculectomy. Dr David Holcombe at Toowoomba Ophthalmic Consultants offers MIGS procedures, often performed at the time of cataract surgery, to help reduce or eliminate the need for glaucoma eye drops.
What is Minimally Invasive Glaucoma Surgery (MIGS), and who is it suitable for?
MIGS refers to a group of newer, less invasive surgical procedures designed to lower eye pressure with a faster recovery and fewer risks than traditional glaucoma surgery. These procedures typically involve the insertion of microscopic drainage devices or stents into the eye's natural drainage pathway. MIGS is often suitable for patients with early to moderate open-angle glaucoma, particularly those who have difficulty using eye drops or are undergoing cataract surgery. Dr Holcombe can advise whether you are a candidate for MIGS.
Can glaucoma be cured with surgery?
Currently, there is no cure for glaucoma, and any vision loss from the disease is permanent. The goal of all glaucoma treatment whether it be eye drops, laser, and surgery is to slow or stop the progression of the disease by lowering intraocular pressure. This reduces the risk of further vision loss. Treatment is aimed at preserving your remaining vision for as long as possible.
How long does recovery take after MIGS glaucoma surgery?
Recovery after MIGS is generally faster and more comfortable than with traditional glaucoma surgery. Most patients experience mild discomfort, redness, or blurry vision for a few days. You will likely be advised to use antibiotic and steroid eye drops for a few weeks to prevent infection and reduce inflammation, and to avoid rubbing your eyes, heavy lifting, or bending over for at least a week. Your specialist will schedule follow-up appointments to monitor your eye pressure and healing.
