The use of crude practitioner to population ratios when age-specific ratios are more appropriate can lead to significant errors in estimates of the need for health care manpower. A comparison of these 2 methods is made using age-specific data for Florida as an example. A brief survey of other epidemiological factors affecting clinical manpower projections is given.
It has been postulated that the BP/IOP ratio is more predictive of glaucoma than is tonometry alone. An analysis of clinical data from 128 glaucoma patients and 115 normals yields a sensitivity of 80%. Specificity of 86% and relative risk ratio of 22 for this screening test. Evidence of the existence of a dose-response relationship is also found.
Clinical estimates of ocular blood flow, based on a comparison of systemic blood pressure and intraocular pressure, appear to be better predictors of glaucomatous visual field loss than are tonometric estimates alone. One index of ocular hemodynamic status is the blood pressure/intraocular pressure ratio (BP/IOP). A nomogram is presented to aid in calculating this index.
