Optical coherence tomography (OCT) is a commonly used imaging modality in the evaluation of glaucomatous damage. The commercially available spectral domain (SD)-OCT offers benefits in glaucoma assessment over the earlier generation of time domain-OCT due to increased axial resolution, faster scanning speeds and has been reported to have improved reproducibility but similar diagnostic accuracy. ...

For quite some time, glaucoma has been regarded as more than just intraocular pressure [IOP] elevation. Significant contribution to this conceptual improvement has risen from a better understanding of ocular blood flow, vessel wall integrity and certain advanced ideas in neuroophthalmology, for example neuroprotection. Transforming growth factor-β (TGF-β) molecule, its inhibitors and antagonist...

Patients with glaucoma and glaucoma suspects encompass a large group of individuals—up to 5% of the population over the age of 40 years, and an even higher prevalence in older age groups. With aging of the Canadian population, the number of affected individuals with glaucoma or glaucoma suspects is expected to increase dramatically, placing significant stresses on the resources devoted to eye c...
