PURPOSE Because several polypeptide growth factors are known to influence capillary endothelial cell mitogenesis, the authors investigated the presence of some of these molecules in choroidal neovascular membranes (CNVMs) removed surgically from human subjects with age-related macular degeneration (ARMD). METHODS The authors performed immunoelectron(More)
PURPOSE To determine whether vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF), which have been implicated in the development of retinal and choroidal neovascularization, are present in the retinas and optic nerves of patients with diabetes before proliferative retinopathy appears. METHODS Light microscopic(More)
The authors describe the unexpected finding of cicatrization of posterior chamber lens haptics to the pars plana. This was found during removal of a secondary, transscleral sewn-in pseudophakos during a retinal reattachment procedure. Ophthalmic history and intraoperative photography revealed pars plana cicatrization of haptics. Despite removal of(More)
Amiodarone has been implicated in the pathogenesis of optic neuropathy in several cases. However, that relationship is unclear, as subjects placed on amiodarone represent a high-risk group for various vasoocclusive accidents. In order to investigate the effect of amiodarone on the optic nerve, we examined histopathologically sections of the retrobulbar(More)
Three patients with myasthenia gravis had transient retraction of the upper eyelids which usually followed prolonged upgaze and which persisted for many seconds. This could result from post-tetanic facilitation, myotonia, or a transient contracture. Retraction of this type is to be distinguished from both the long-standing unilateral retraction associated(More)
