Editorial: Update on Glaucoma Diagnosis and Management.

Glaucoma is one of the most dreadful ocular conditions that affects millions of people worldwide and is one of the major causes of irreversible blindness. Although glaucoma is a complex and poorly understood disorder, the primary goal of therapy is lowering Intraocular Pressure (IOP), which is not only one of the most significant risk factors in development of the disease, but also the only modifiable one. Therefore, a precise measurement of IOP is essential for accurate diagnosis and effective monitoring of glaucoma. Goldmann applanation tonometry is the gold standard method for IOP measurement. It has been known that IOP measurement by this method is affected by corneal properties; typically, thick corneas overestimate and thin corneas underestimate the IOP. Therefore, several methods had been introduced to correct IOP based on the central corneal thickness. However, those methods had oversimplified the problem, and ignored important factors such as corneal viscosity and elasticity. New generation of devices such as Ocular Response Analyzer (Reicherts) and CorVis ST (Oculus Inc.) have been devised that can account for corneal biomechanical properties when measuring IOP. It is claimed that these methods are particularly useful for eyes with inherently abnormal and surgically altered corneal biomechanics such as those who have undergone laser vision correction or keratoplasty [1].
