e-Poster Rio de Janeiro Corneal Tomography and Biomechanics Study Group e-Poster Rio de Janeiro Corneal Tomography and Biomechanics Study Group Pentacam HR and ORA was performed in cases with: Corneal Thickness Profiles and ORA parameters will be correlated. Specular microscopy was performed in all cases to document endothelial counts and presence or not of corneal guttae. Methods Thin cornea - normal biomechanics“Normal” Thick Cornea with Ocular Hypertension Thicker cornea with Fuchs dystrophyEndotheliitis Keratoconus with FuchsEarly Edematous Thick Cornea with Glaucoma
