What is refractory glaucoma?
Refractory glaucoma is defined as uncontrolled intraocular pressure with evidence of optic nerve and/or visual field deterioration despite maximally tolerated anti-glaucoma medications (topical and/or systemic), previously failed non-seton surgical treatment, or a combination of surgery and medicines or a high risk of …
What is ECP for glaucoma?
ECP is a procedure in which a laser is used to alter part of the ciliary body, which lies behind part of the iris (the colored part of the eye). How does ECP work? The eye is constantly producing fluid through the ciliary body. When this fluid cannot leave the eye, the pressure goes up and glaucoma can result.
What is Transscleral Cyclophotocoagulation?
Transscleral cyclophotocoagulation (TSCPC) using the G-Probe glaucoma device is a long-term, effective intraocular pressure lowering procedure for many types of glaucoma patients. Patients with refractory glaucoma and those with good visual acuity can benefit from TSCPC using the G-Probe.
What is a Xen implant?
The XEN® Gel Stent is a small surgical implant designed for use in minimally invasive glaucoma surgery. The procedure helps drain fluid and reduce intraocular pressure (IOP) in open angle glaucoma patients, thus preserving vision. It is also referred to as aqueous shunt surgery.
What is a Trabectome surgery?
Trabectome surgery is a minimally-invasive glaucoma surgery that has been available since 2005 to lower eye pressure. It is usually effective, has a good safety profile and is usually combined with cataract removal to lower eye pressure.
What is Hypotony?
Hypotony is usually defined as an intraocular pressure (IOP) of 5 mm Hg or less. Low IOP can adversely impact the eye in many ways, including corneal decompensation, accelerated cataract formation, maculopathy, and discomfort. Clinically significant changes occur more frequently as the IOP approaches 0 mm Hg.
How do you perform Cyclophotocoagulation?
The Procedure During a transscleral cyclophotocoagulation treatment, a laser probe is placed on the white wall of the eye, just outside the circle formed by the iris and the cornea, and 15 to 30 laser treatment spots are administered.
What happens after Xen gel stent surgery?
The first few days after surgery, vision may be blurry and even worse than it was before surgery. This will improve over several weeks, although it can sometimes take longer. The eye that was not operated on will not be affected, and may be depended on for vision during the recovery period (if it has vision).
What are the risks of cyclophotocoagulation for glaucoma?
Common risks of cyclophotocoagulation include inflammation, which can cause the front of the eye to show signs of inflammation, or less commonly, the retina to swell ( macular edema ). Other more common risks include bleeding, especially in patients with a form of glaucoma called neovascular glaucoma.
What is cyclophotocoagulation and how does it work?
In summary, cyclophotocoagulation is a laser procedure that helps lower the eye pressure by targeting the part of the eye that produces fluid (ciliary processes). It can be very effective at lowering eye pressure, and the newer techniques are less invasive than traditional cyclophotocoagulation.
What is the difference between Endocyclophotocoagulation and laser eye surgery?
Finally, endocyclophotocoagulation also utilizes an 810 nm laser probe, but instead of applying the treatment on the outside surface of the eye, this surgery requires an incision into the eye, and the laser probe has a camera that allows the surgeon to directly visualize the ciliary processes.
What are the side effects of glaucoma treatment?
Less common side effects include vision loss, hypotony (described above), and a condition called sympathetic ophthalmia. In sympathetic ophthalmia, which is very rare, the untreated eye can begin “sympathizing” with the treated eye and become inflamed.
