Pan-retinal photocoagulation (PRP)
Pan-retinal photocoagulation is a form of treatment is for the eye. It is used to treat conditions where the retina is severely damaged with significant ischaemia. in response, the retain may secrete some material that can lead to the development of abnormal new blood vessels. These abnormal vessels are fragile and can bleed easily.
The laser aims to treat these areas of retinal damage. This would help to stop the proliferation of new blood vessels and to prevent further damage. This laser modality is used in conditions like:
- Proliferative diabetic retinopathy
- Ischemic retinal vein occlusion
- Neovascular glaucoma
Focal is used to selectively target areas of the damaged retina or leaking blood vessels. Few laser shots are applied over the damaged retina. This laser treatment is commonly used for the treatment of diabetic macular oedema.
Sector laser treatment
Some retinal diseases can affect only a sector of the retina. The damaged retinal sector may release some materials that can lead to the proliferation of new blood vessels. These new blood vessels are fragile and can easily bleed into the gel of the eye (vitreous). The laser is applied to the damaged retina to prevent further complications.
Laser for retinal holes or tears (Retinopexy)
The laser is used to seal retinal holes or tears. This is called retinopexy. The laser is applied all around the hole or tear to seal it. This would help to prevent the hole or tear to progress to a retinal detachment.
Mr Ellabban will assess you and discuss with you which type of laser treatment is indicated in your case, details of laser treatment, risks and benefits, and advise you about the procedure.
