What does it involve?
This technique consists of applying a laser to the damaged areas of the retina to treat or prevent retinal problems.
When is it carried out?
It is performed for many retinal disorders, including the repair of retinal tears to prevent detachment and the treatment of retinal vascular diseases, diabetic retinopathy, vein blockage, aneurysms, etc.
Prior examination
A comprehensive eye examination and, in most cases, a fluorescein angiogram is required. An optical coherence tomography test (OCT) is also often required.
Before the surgery
Applying laser photocoagulation to areas where it is not necessary should be avoided. This could cause burns.
Surgery
The procedure is performed under topical anaesthesia with eye drops; the laser is directly focused on the lesions and guides us to where the photocoagulator will be applied.
Risks
Photocoagulation can prove ineffective or insufficient, or damage important retinal structures, such as blood vessels or the macula area.
