in contrast to the already-established methods of measuring ocular perfusion -- ophthalmodynamometry and ophthalmodynamography after hager -- the advantages of oodg are that it not only enables the systolic retinal pressure to be differentiated from the systolic ciliary or diastolic ocular perfusion pressure , but also permits the results of the investigation to be illustrated graphically , so that objective evaluation is possible .
