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.
And finally when everything else has failed or the visual potential is so poor, a cyclodestructive procedure
which can be repeated several times for IOP or pain control is recommended .
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
Those refractory to medical therapy may require surgical intervention in the form of cyclodestructive procedures
, retrobulbar injection of absolute alcohol and evisceration or enucleation.
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.
surgical options are goniotomy, trabeculotomy, aqueous shunt procedures or cyclodestructive procedures
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.
Several cyclodestructive procedures
have been proposed during the past 70 years.
Hypotony is a common side effect after cyclodestructive procedures
. Cyclodiode treatment has a lower incidence of hypotony compared to cyclocryotherapy.
Glaucoma drainage implants, nonpenetrating surgery, and cyclodestructive procedures
are other options [3, 4].
