Vitrectomy for CME in retinal vein occlusions — A new indication?
Cystoid macular edema (CME) is the most common cause of visual impairment in vein occlusions. So far the “good clinical praxis in branch vein occlusions (BRVO)” and CME was a grid laser therapy [16, 18]. Vision improvement after grid laser occurs in 65% of the patients. If we look closer to what appears to be a remarkable advantage we find that the average vision improvement was just 1.3 lines, that 40% of the patients lost reading vision and patients with lower vision were less likely to achieve a good vision after grid laser. Furthermore, in patients with CME and capillary non perfusion laser failed to show any effect and in central retinal vein occlusions (CRVO) grid laser therapy also could not improve the visual prognosis.
