When Should You See a Retina Specialist?
Some retinal conditions progress slowly, while others can threaten vision quickly. Knowing which symptoms need urgent attention—and which risk factors justify routine review—can help you seek the right care at the right time.
The short answer
You should see a retina specialist when you develop symptoms suggesting a problem at the back of the eye, when an optometrist or doctor identifies a retinal abnormality, or when an existing condition such as diabetes or macular degeneration needs specialist monitoring or treatment.
Sudden flashes, a rapid increase in floaters, a curtain or shadow, or sudden vision loss require prompt professional assessment.
Symptoms that should not wait
Contact an eye-care professional promptly if you notice:
- A sudden shower of new floaters
- New flashes of light, especially in one eye
- A dark curtain, veil or shadow across your vision
- Sudden loss of peripheral or central vision
- New distortion where straight lines appear bent or wavy
- Sudden blurred vision following an eye injury
These symptoms do not always mean a retinal emergency, but a retinal tear or detachment needs to be excluded. If urgent eye care is unavailable, attend your nearest emergency department.
Reasons for a non-emergency retinal consultation
Persistent distortion or central blur
Changes in the macula can affect reading, recognising faces and fine detail. OCT imaging may help identify swelling, an epiretinal membrane, a macular hole or macular degeneration.
Diabetes-related eye changes
Diabetic retinopathy can develop before vision changes are obvious. A retina specialist may be involved when screening shows bleeding, abnormal vessels or diabetic macular oedema.
Retinal vascular disease
A retinal vein occlusion can cause sudden or gradual blur and retinal swelling. Specialist imaging helps determine the area affected and whether treatment is appropriate.
Vitreous or surgical conditions
Vitreous haemorrhage, macular hole, epiretinal membrane and retinal detachment may require monitoring, laser, injections or vitreoretinal surgery.
Who may need regular retinal monitoring?
Your recommended examination schedule depends on your individual findings. More regular review may be advised if you have:
- Diabetes or previously diagnosed diabetic retinopathy
- Age-related macular degeneration
- High myopia or peripheral retinal degeneration
- A previous retinal tear or detachment
- Retinal surgery or treatment in either eye
- A family or personal history of certain inherited retinal diseases
- Medication or systemic disease that can affect the retina
Routine monitoring is different from urgent assessment. If new warning symptoms develop between scheduled visits, contact your eye-care provider rather than waiting for the next appointment.
Do you need a referral?
You can contact an ophthalmology clinic to discuss an appointment. In Australia, a current referral from a GP, optometrist or another specialist is generally needed to claim an applicable Medicare rebate. Your referrer can also provide useful information about the reason for review and any earlier examination findings.
What happens after you are referred?
A retinal assessment usually starts with a discussion of your symptoms, medical history and medications. Vision and eye pressure are checked, and pupil-dilating drops may be used to examine the peripheral retina. Depending on the problem, your specialist may recommend OCT, retinal photography, fluorescein angiography or ocular ultrasound.
Once the findings are reviewed, your specialist will explain whether you need observation, further testing, injections, laser treatment or surgery. If you want a detailed walkthrough, read our guide to what happens at a retina specialist appointment.

Frequently asked questions
Can retinal disease develop without symptoms?
Yes. Early diabetic retinopathy and some peripheral retinal changes may cause few noticeable symptoms. This is why examination intervals should be based on your risk factors and clinical findings.
Are all new floaters dangerous?
No, but a sudden onset or rapid increase—particularly with flashing lights, a shadow or reduced vision—requires prompt assessment to exclude a retinal tear.
Should people with high myopia have retinal checks?
High myopia is associated with an increased risk of certain retinal changes. Your optometrist or ophthalmologist can recommend an examination schedule based on your prescription and retinal findings.
Can I drive after a dilated retinal examination?
Dilating drops can temporarily blur near vision and increase light sensitivity. Bring sunglasses and consider arranging transport, particularly if you have not been dilated before.
