title: An objective focusing method for fundus photography.
abstract: A method is described which enables the fundus camera to be focused objectively. This method eliminates the focus errors arising from the subjective focusing method currently used and permits the consistent attainment of high resolution fundus photographs.  The objective focusing method has been evaluated on test targets and anesthetized animals and is applicable for use on unanesthetized human subjects.
