Purpose: : To evaluate the reprodutibility of Orbscan measurements in pathological corneas

Methods: : Five measurements of each eye was taken every five minutes and tis results analysed

Results: : Anterior elevation map and posterior elevation showed showed poor reprodutibility in patients with severe corneal pathology. Corneal thickness map and posterior corneal mpas showed good reprodutibility in patients with mild to moderate keratoconus. Patients with severe (advanced) corneal disease showed poor reprodutibiliy on orbscan maps

Conclusions: : Orbscan is a relatively safe and effcient method for evaluating corneal curvature and thickness in inital cases of keratoconus and PMD. However the reprodutibiliy of the exams decrases significantly when severe cases of keratoconus and PMD is analyzed.

Keywords: cornea: clinical science • topography • keratoconus
