抄録

An intravitreal cannula for chronic drug delivery was implanted in the eyes of two rabbits and one monkey. The rabbits were followed up for three years after surgery and the monkey was followed up for two and one-half years. Clinical observations did not reveal any adverse effects from the cannula implantation. Patency of the cannula was demonstrated by using sodium fluorescein. Histopathological studies with light and electron microscopy revealed the scar tissue around the cannula to be minimal and localized to the wound site. The optic nerve and the retina and choroid at the posterior pole did not show any abnormalities. These results suggest that this system can be used for repeated or continuous drug delivery to the vitreous over a long period of time in experimental models.
