This book aims to provide the readers with an up-to-date and evidence-based management approach for primary angle closure glaucoma (PACG), which makes effective and safe use of all the interventions currently available. The book presents to the glaucoma subspecialists and the general ophthalmologists a clear and concise introduction to the latest advances in the management of primary angle closure glaucoma (PACG), from the latest imaging technologies to objectively quantify the drainage angle closure and structural glaucomatous progression, to an up-to-date review of the laser and surgical options for treating PACG. The laser and surgical interventions include laser peripheral iridotomy, laser peripheral iridoplasty, lens extraction alone or in combination with other glaucoma surgery, filtration surgery (including minimally-invasive and non-penetrating variants), goniosynechialysis (GSL), glaucoma drainage device implantation, and cyclodestructive procedures. This informative book, written based on the authors’ vast clinical, teaching, and research experience in this field, will offer the readers in-depth and useful resources on PACG.
