Moreover, administration of these drugs can cause a significant hazard of bleeding, e.g., vitreous and cerebral haemorrhage and other systemic complications. veg increases vascular permeability, leading to macular enema and development of neovascularization. The condition leads to neovascularization in various eye tissues due to the ischemia. The authors claimed that it “is a relatively safe procedure” but their data shows that the extent of complications reported by the authors is so high as to be totally unacceptable 14. Ophthalmology. 2011 Jan. 1181:119-133.e1-2. These limitations include: During the very early stages, in spite of retinal ischemia, retinal capillary non-perfusion may not be seen, because it takes time for the retinal capillaries to obliterate completely.

Other complications of ischemic CRVO are vitreous haemorrhage, macular degeneration, optic atrophy, retinitis proliferans, phthisis bulb or loss of eye. Visual outcome: There are only two series with any appreciable number of cases reported so far. With ciao the retina will be pale and the vessels narrowed.
