Abstract
A simplified practical technique for biopsy of retina and choroid was developed in dogs. A 270.degree. circular scleral flap of 3 mm diameter is raised. The risk of chorioretinal bleeding and vitreous loss are greatly reduced by i.v. mannitol and controlled hyperventilation, with hyperoxygenation and transient, systemic hypotension under general anesthesia. Reasonable ultrastructural detail was preserved in chorioretinal specimens of 1 mm diameter. Repeat biopsies in the same eye are feasible without significant complications.
