Statistics from Altmetric.com

Several vascular endothelial growth factor inhibitors have recently been studied as treatments for neovascular AMD.1 2 Pegaptanib sodium improved visual acuity in 6% of patients at one year;1 Ranibizumab 0.5 mg improved vision by three lines in 33% of patients at one year.2 Michels et al.3 initially reported the use of intravenous bevacizumab for the treatment of choroidal neovascularization (CNV), and others have found visual improvement and reduction in macular thickness with intravitreal bevacizumab.48 We present the results from 118 cases treated with intravitreal bevacizumab based at a single centre.

Methods

A retrospective review of 115 consecutive patients (118 eyes) based at Southampton Eye Unit, treated with intravitreal bevacizumab for CNV was performed. Lesions of all types irrespective of size or location that were either ineligible for photodynamic therapy (PDT) under the National Health Service (including minimally classic and occult CNV) or those not responding to PDT (classic or predominantly classic CNV with recurrent or persistent CNV activity) were included in the study (table 1). All patients underwent visual acuity testing (best corrected Snellen), slitlamp examination and fundus fluorescein angiography. Central macular thickness (CMT) was assessed using Stratus optical coherence tomography (Carl Zeiss Meditec, USA).
