I read with interest the case series in the November 2006 issue of the Archives in which Warden et al1 describe 3 patients who developed choroidal neovascularization (CNV) following uncomplicated pars plana vitrectomy with membrane peel.
Although it is suggested that CNV developed following membrane peel presumably owing to disruption of the Bruch membrane, Warden and colleagues fail to provide preoperative imaging (fluorescein angiography or optical coherence tomography) findings to support their hypothesis. The documentation provided does not strongly support surgical causation; rather, the membranes were either preexistent and/or due to comorbid disease.
