In some cases, cyclodestructive procedures seem to be a valid option to lower the IOP until definite surgery can be performed.
Failures were defined as IOP <6 mm Hg or >18 mm Hg, loss of light perception, loss of vision due to complications, removal of the implant or the need for further surgical intervention for IOP control including cyclodestructive procedures.
Transpupillary argon laser cyclophotocoagulation (TALC) is an alternative cyclodestructive procedure in selected patients with glaucoma.
Patients who had undergone the following procedure such as previous cyclodestructive procedure, scleral buckle procedure, glaucoma drainage device implantation, or silicone oil surgery were excluded from the study.
Those refractory to medical therapy may require surgical intervention in the form of cyclodestructive procedures, retrobulbar injection of absolute alcohol and evisceration or enucleation.
Cyclodestructive procedures may be done in eyes with limited visual potential.
As for cyclodestructive procedures (cyclocryotherapy and cyclophotocoagulation), they are efficient in reducing the IOP but cannot be considered as first line treatments because they exhibit important complications like phthisis bulbi and retinal detachment (both appear in 50% of cases), progressive lens opacification and blindness [1,13, 21, 22].
They focus on the use of these techniques to address intraocular pressure control and detail the history of glaucoma surgery, the evolution of defining MIGS, basic anatomy and wound-healing considerations, and specific devices and approaches, including trabecular meshwork bypass devices, Schlemm's canal devices, suprachoroidal devices, ab interno stenting procedures, ab interno trabeculectomy, endocyclophotocoagulation and other cyclodestructive procedures, and cataract surgery, ending with emerging surgical interventions and non-MIGS procedures.
While descriptions of surgical management in this text are centred on more common types of glaucoma, such as paediatric, angle closure and laser approaches to management, not to mention how to deal with concurrent cataract extraction in glaucoma filtration surgery, the text does not shy away from discussing more modern techniques such as the minute stent procedure, which aims to increase aqueous outflow at Schlemm's canal in order to reduce intraocular pressure, to cyclodestructive approaches which are reserved for patients who are unresponsive to even surgical methods of glaucoma management.
It contains 60 chapters, presented in sections covering introductory topics, laser therapy, trabeculectomy, nonpenetrating glaucoma surgery, management of coexisting cataract and glaucoma, drainage devices, surgery for congenital glaucoma, modulation of wound healing, cyclodestructive procedures, and new procedures.
Patients were excluded if they met the following criteria: (1) previous cyclophotocoagulation or other cyclodestructive surgery, (2) the presence of glaucoma drainage device, (3) ocular infection, (4) other diseases that can affect intraocular pressure (such as choroidal detachment and subluxation of the lens), or (5) pregnancy or serious systemic disease.
