WebThe second RPE tear occurred after an average of 7.1 ± 5.2 injections of anti-VEGF owing to constriction of the fibrous vessels induced by anti-VEGF therapy. Although a “double RPE tear” occurred, as in previous studies, the patient’s vision was not significantly affected because the macula was not involved. 80. WebA key role in angiogenesis is played by vascular endothelial growth factor (VEGF). The regulation of blood vessel growth to match the needs of the tissue depends on the control of VEGF production through changes in the stability of its mRNA and in its rate of transcription.
