Patients with choroidal neovascularization
CNV due to Age-Related Macular Degenerations and Myopia were included.
Visual Evoked Potential and Elctroretinogram
To evaluate the retinal and optic nerve functions of bevacizumab when injected intravitreal in human eyes using electrophysiological tests; Electroretinogram (ERG) and Visual Evoked Potentials (VEP). Forty five eyes of 45 patients with choroidal neovascular membrane (CNV) who were prepared for intravitreal injections of 1.25mg bevacizumab underwent baseline ERG and VEP in both eyes before, and at 1 and 4 weeks after the intravitreal injections.
