Retinal conditions can affect the retina (including the macula) and the vitreous – some of the main conditions are mentioned below.
These will vary depending on the exact condition, for example:

Complete the form below and we will contact you to arrange an appointment. You will need to bring a current referral letter from a GP or optometrist to your consultation. If you are interested in laser eye surgery and require a referral letter, an appointment can be arranged with one of our optometrists to organise this.

The examination usually begins with an ophthalmoscope to look inside the eye and directly visualise the back of the eye. This requires your pupils to be dilated using eye drops. It’s important to note that your eyes will remain dilated for approximately 4 to 6 hours and your vision will be blurry, meaning that you may not be able to drive home – please make other arrangements.
After dilating your pupils, your ophthalmologist may use a special condensing lens and a bright light, usually mounted on their forehead, to evaluate the retina, the optic nerve and tiny blood vessels. A retinal tear or retinal detachment can often be detected during this type of examination.
Other tests may be necessary to assess the severity of your condition, diagnose other retinal conditions and guide treatment.
State-of-the-art equipment is used to produce high-resolution photographs of your retina, optic nerve and blood vessels. The photographs help your ophthalmologist detect changes in these areas, as well as in the macula (in the centre of the retina). Your retinal photographs will be kept in your medical records and used as a comparison if more are taken at a later stage.
A fluorescein angiogram uses a fluorescent dye to show any blockages or leaks in the tiny blood vessels supplying the retina. The dye is usually injected into a vein in your arm and flows through the blood system to the vessels at the back of the eye. Your ophthalmologist can detect any blockages or leaks and will use a special camera to take photographs. Your vision will be blurred for up to 12 hours after the test.
OCT is a non-invasive test that captures detailed images of the retina. This scan allows your doctor to identify areas of retinal thinning, thickening or swelling caused by fluid build-up and leaking blood vessels. The OCT scans your eyes without making direct contact. The procedure takes less than 10 minutes.
This is a simple test you can do at home to alert you to any vision changes that may indicate the presence of macular degeneration or epiretinal membrane. The Amsler Grid contains a series of horizontal and vertical lines with a dot in the middle. If the lines appear wavy or lines are missing, have your eyes checked immediately.
The two most common diseases treated with laser are retinal tears (to seal the retinal layers together) and diabetic retinopathy (to stop leakage from small blood vessels that cause swelling or stop new blood vessels from growing).
Laser treatment aims to lower the risk of further vision loss – it is unlikely that lost vision will be recovered.
A vitrectomy involves removing the vitreous gel (the clear, jelly-like fluid inside your eye) using keyhole surgery so that stitches are not needed. It is performed in the day surgery – the procedure itself usually takes around 30 to 45 minutes.
Once the vitreous is removed, it is replaced with a bubble of gas or sterile saline. Silicone oil may be used if the retina has been detached for a long time or retinal scarring is present.
Laser or freezing treatment is used to seal the retinal tears.
Because gas and oil bubbles float upwards, you will need to keep your head in a certain position for a number of day after the surgery to place the bubble in the correct position, while the retina is healing. The silicone may remain in the eye for months, or it can be removed after the retina has healed.
A protective eye patch is necessary for about 24 hours afterwards, followed by eye drops and ointment. Generally, patients can resume their regular activities after a day or so, although this can vary from person to person. A vitrectomy may be needed to treat:
These injections are also called intravitreal injections. They are administered in the clinic or day surgery. The eye is numbed with a local anaesthetic to stop any pain. Ongoing treatment is often necessary for many of the disorders.
