Ex-Press mini glaucoma shunt
Ahmed Valve, preparation for surgery
The video demonstrates the way to prepare an Ahmed Glaucoma Valve for surgery. The first step is to prime the valve with balanced saline solution, after that we pre set a 7-0 silk double armed without cutting it, now the implant is ready for surgery
Selective laser trabeculoplasty
Selective Laser Trabeculoplasty (SLT) for glaucoma to lower intraocular pressure. Note the micro bubbles upon lasering the trabecular meshwork.
Ritch Trabeculoplasty Laser Lens.
Power: 1.0 mJ
Spot Size: 400 um
Duration: 3 nanoseconds
Argon laser to cyclodialysis cleft
The patient developed a cyclodialysis cleft after airbag injury that was diagnosed clinically and with UBM. She had a pressure of 0-2 mmHg. After no improvement with Atropine for 2 months, the patient underwent cleft laser.
Trabeculotomy
The surgical treatment of choice for congenital glaucoma is either a trabeculotomy or goniotomy. Both of these procedures surgically open up the immature, non-functioning trabecular meshwork and aim to restore normal outflow of aqueous from the anterior chamber to the Schlemm's canal. If surgery is succesful, intraocular pressure can be adequately controlled without the need for long-term topical medications. Dr Young Kwon is performing this procedure.
Ahmed valve and scleral buckle revision
This patient had narrow / angle closure glaucoma and a corneal graft. She has had 10 previous surgeries. In order to make room for the Ahmed Valve plate, a piece of the scleral buckle is removed.
Transscleral cyclodiode
Transscleral diode cyclophotocoagulation is a procedure for glaucoma that have failed other treatments. In this procedure, the ciliary body of the eye, which creates aqueous fluid, is treated with laser to decrease production of aqueous. This procedure lowers the pressure in the eye. The video explains the steps in this procedure and is produced by ophthalmologists at the University of Iowa.
Insertion of Molteno tube
Patient with decreasing visual field and suboptimal IOP control. This is her second tube placement OS.Procedure performed: Molteno 3 implant inferior 6 o'clock position. Tutoplast patch graft. Tube tied off.
Revision of trabeculectomy
This video illustrates a case of a gentleman with a nasal trabeculectomy now with dysesthesia. A conjunctival flap, bleb revision is shown.
Baerveldt, vitrectomy and corneal transplant
This case shows an opacified cornea secondary to Herpes Keratitis with previous Corneal Transplant. The procedure performed in this video is Baerveldt implant revision, Temporary Keratoprosthesis, Pars Plana Vitrectomy, Corneal Transplant Right eye. Tutoplast patch graft placement.
MMC trabeculectomy and trabeculotomy
This is a case of congenital glaucoma that failed previous treatments and surgeries. In this video, Dr. Kwon demonstrates a combined surgical approach using Mitomycin C trabeculectomy with trabeculotomy.
Endoscopic cyclophotocoagulation
Endoscopic Cyclophotocoagulation (ECP) in eye with post-penetrating keratoplasty glaucoma. The surgery is approached through a limbal incision over the PC-IOL. A haptic pierces the capsule. Also seen are irido-capsular adhesions and a failed trabeculectomy.
Iridotomies using YAG and argon lasers
Video demonstrations of using YAG and Argon lasers to produce a peripheral iridotomy in cases of narrow angle glaucoma.
Yag laser trabeculoplasty
Scott Geller MD of Fort Myers Florida uses A LASAG Yag laser is in thermal mode, 1.5 Joules/pulse to treat the trabecular meshwork between the cornea and iris for glaucoma.
Ahmed valve for neovascular glaucoma
Placement of an Ahmed valve with the drainage tube in the anterior chamber in an eye with unconrolled neovascular glaucoma. This 81 year old man has been managed for 3 months with laser, drops and oral medications for neovascular glaucoma induced by a central retinal vein occlusion. His intraocular pressure is between 30 and 40 despite maximal medical therapy. He also has a history of heart failure. Some of his glaucoma medications cannot be continued without risk of exacerbating his heart disease. His visual acuity is 20/160 in this eye. His other eye is 20/60 because of a macular pucker.
Trabeculectomy with mitomycin C
Trabeculectomy with mitomycin C in a case of juvenile open angle glaucoma. Performed by Dr Graham Lee, Queensland, Australia.
Trabeculectomy
One of the various variations of trabeculectomy surgery for glaucoma demonstrated by Dr.Sarbjit Singh of India.
