| Brief Title ICMJE | Influence of Discordant Intraocular Eye Pressure Readings Taken by Dynamic Contour Tonometry and Goldmann Applanation Tonometry | ||||
| Official Title ICMJE | Not Provided | ||||
| Brief Summary | IOP is measured with two devices (Dynamic Contour Tonometry (DCT) and Goldmann applanation tonometry (GAT)). DCT reading will be compared to a corrected GAT reading by the formula of Elsheikh, Alhasso and Pye.
