Comparison of endothelial evaluation techniques

Comparative evaluation of the corneal endothelium with the Heyer-Schulte specular photomicroscope, the McIntyre CEB reticle affixed to a slitlamp, and a slitlamp alone found the reticle-slitlamp combination to give results within a 10% average of endothelial cell counts determined with the specular microscope. The reticle also compared favorably in time and cost savings. All three methods of corneal evaluation were effective for observation of polymegathism. Because of its lower magnification, the slitlamp without the reticle was best suited for evaluation of cornea guttata.
