What does it involve?
Intravitreal injections are used to locally administer medication to treat the secondary complications of diabetic retinopathy.
When is it carried out?
The treatment is mainly indicated for diabetic macular oedema (accumulation of fluid in the macula), in which corticosteroids or anti-angiogenic drugs are administered intraocularly.
Examination of the eye and fundus. In most cases, an OCT test is performed, and, in some cases, a fluorescein angiogram is also indicated.
Before the surgery
Before the injection, the eye and eyelids are disinfected. After the injection, antibiotic eye drops have to be administered for a few days.
The injection itself is a short procedure. It can be carried out in theatre or in the doctor’s surgery, but always under strict asepsis conditions. It is performed under topical anaesthesia (eye drops) and does not generally cause discomfort.
As in all surgical interventions, the greatest risk is eye infection. If the correct prophylactic measures are employed, however, the risk is minimised (much lower than after cataract surgery, for example).
It is a grid of straight horizontal and vertical lines with a central point, used as a tool to detect visual disturbances in patients with scotoma or other anomalies.
It is much more likely for haemorrhages to occur after surgery, especially if a vitrectomy has been performed, in the case of patients with diabetic retinopathy. This is due to the vessel walls being extremely fragile in these patients and more prone to bleeding.
Yes, it is an emergency, but relatively speaking, as it is possible to wait 3 or 4 days. It is necessary to examine the eye, because the symptom could indicate the onset of decompensation, which can cause severe loss of vision. This distortion is sometimes not due to decompensation, but it always needs to be confirmed.
