Damage to the optic nerve causes gradual vision loss. This may occur due to a group of eye diseases called glaucoma. Open-angle glaucoma, closed-angle glaucoma and normal-tension glaucoma are some types of glaucoma. Testing for glaucoma comprises of an eye examination with measurements of the intraocular pressure, an anterior chamber angle examination, and optic nerve evaluation. Scanning laser polarimetry, optical coherence tomography and scanning laser ophthalmoscopy help in assessing the retinal nerve fiber. Vision loss due to glaucoma is permanent. If the disease is detected early, it may be possible to slow or even stop the progression of the disease with the aid of laser treatment, medication or surgery. These treatments seek to lower eye pressure. This book is a valuable compilation of topics, ranging from the basic to the most complex advancements in the diagnosis and management of glaucoma. From theories to research to practical applications, case studies related to all contemporary topics of relevance to this condition have been included herein. It will help new researchers by foregrounding their knowledge in glaucoma.
