Retinal vein occlusion constitutes the second mostcommon retinal vascular disorder coming after diabeticretinopathy. Panretinal photocoagulation has beenwidely used as the treatment of choice. The presumedrole of it is to prevent the development of vitreoushemorrhage and neovascular glaucoma after occurrenceof neovascularization in eyes with retinal ischaemia.
