The methodology currently used for interpretation of the cornea and anterior segment tomography for the diagnosis of corneal ectasia. Description of the clinical interpretation of anterior segment tomography (Pentacam – Oculus, Wetzlar, Germany); case report of the ectopia lentis demonstrating the importance o evaluation of the cornea and anterior segment of the keratoconus. We excluded the disease, analyzing the tomographic analysis of rates of ectasia and observe an asymmetry between nasal and temporal sides in assessing the depth map of […]

OBJECTIVE: To evaluate the safety of PRK in patients with atypical corneal topography, but without features of keratoconus in Pentacam. METHODS: Medical records of patients who underwent PRK method that presented atypical corneal topography and Pentacam rates considered normal in the pre operative were analyzed. The sample consisted of nineteen eyes of ten patients. The considered criteria of corneal irregularity were: increased curvature greater than 47D with asymmetry less than 1,5D, 1,5D displacement above the apex and inferior-superior asymmetry greater […]

PURPOSE: The methodology currently used for interpretation of the cornea and anterior segment tomography for the diagnosis of corneal ectasia and its susceptibility. METHODS: Description of the methodology and clinical interpretation of corneal and anterior segment tomography indexes; report of three cases demonstrating the importance of this new diagnostic tool (Pentacam HR®) in ophthalmological practice. CONCLUSION: The use of corneal and anterior segment tomography seems to be an effective method to increase the sensitivity and specificity for the diagnosis and […]

The authors report the case of na eighteen years old patient with a clinical picture of orbital abscess caused by ethmoid sinusitis. The decision for surgical intervention results from correlation between clinical findings and from the image diagnosis.
