Because the retina is tucked away behind the eye, it is often forgotten until something goes wrong. Retinal diseases are one of the leading causes of blindness in adults and should not be taken lightly.
What can we treat?
- Wet Age-Related Macular Degeneration (AMD)
- Central and Branch retinal vein occlusion
- Retinal tears and holes
- Retinal detachment
- Diabetic Retinopathy
- Diabetic macular oedema
- Central Serous Retinopathy
- Cystoid Macular Oedema
- Macular Hole and Macular Pucker
- Epi-retinal membrane
- Complex ocular trauma
- Vitreous haemorrhage and opacity
- Retinal vascular disease
- Inherited retinal diseases
- Retinopathy of Prematurity
Fluorescein angiography is a diagnostic procedure where a dye is used to highlight the blood vessels in the back of the eye. The fluorescent dye is safely injected into the bloodstream so doctors can photograph the retinal blood vessels.
Doctors often use these tests to confirm a diagnosis, to monitor the vessels in the eye or to determine an appropriate treatment.
Retinal laser treatments
The retinal laser is a pure, high-intensity beam of light energy. Doctors use these lasers to precisely focus onto the retina and selectively treating a designated area. Because the laser is very precise the surrounding retinal tissue remain untouched throughout the procedure. The retinal laser is used to create microscopic spots to adhere the retinal layers or stop vessel leakage or growth.
Retina laser procedures are usually painless and performed in the clinic. Common retinal laser treatments include:
Pan-retinal photocoagulation for diabetic retinopathy. The laser seals and stops leakage from newly formed small blood vessels, or to stop new blood vessels from forming.
Laser for retinal tears to reattach the tear to the retina and prevent retinal detachment, which is serious and can lead to permanent vision loss if left untreated.
Photodynamic therapy (PDT) is a treatment that uses a photosensitizing agent in combination with a special light. When photosensitizers are exposed to the special light, they produce a form of oxygen that kills nearby cells.
A vitrectomy is a procedure to remove the vitreous gel from the inside of the eye. This is only necessary when the surgeon is required to carry out a procedure that cannot be performed with the fluid in its place.
The vitreous is a transparent and colourless substance which fills about two-thirds of the eye, between the lens and the retina.
Intravitreal steroid injections
Corticosteroid medication used to treat a number of retinal conditions by intravitreal injection. Treatment by intravitreal injection limits any side effects to the eye and body as compared to oral consumption of the medication.
Corticosteroids reduce inflammation, which is common in some retinal disorders. Diabetic retinopathy, central retinal vein occlusion and post-operative macular oedema are sometimes treated with corticosteroids.
Intravitreal anti-VEGF injections
Anti-VEGF treatments have been used to treat a number of eye conditions which cause new blood vessel growth or swelling under the macula area of your retina. These conditions include Wet Age-Related Macula Degeneration, Diabetic Macular Oedema and Retinal Vein Occlusion.
Ozurdex is a steroidal implant injected into the back of the eye. This injection is used to treat adult patients with vision loss due to diabetic macular oedema or swelling of the macula following a retinal vein occlusion.
Vitreolysis treatment for floaters
Until recently, there was no safe and easy way to treat floaters in the eye. A surgical procedure known as vitrectomy was the only option of treating floaters in the eye. Traditionally, this procedure is reserved for patients with retinal detachment and serious eye infections. It involved replacing the eye’s natural fluid with a sterile clear fluid getting rid of the eye floaters altogether. But the risks usually outweigh the benefits and for these reasons, most eye doctors will not recommend vitrectomy to treat eye floaters.
Since the introduction of the vitreolysis procedure, the removal of floaters in the eye has become relatively quick and safe to perform. This non-invasive procedure uses laser pulses to evaporate the floaters in the eye. The vaporised floater is turned into gas which gets absorbed in the eye.
This pain-free procedure can be performed in the clinic and under local anaesthetic eye drops. The procedure takes between 30 to 60 minutes and occasionally, more than one visit is required.
